[0068] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION

[0069] For the purpose of making the objects, technical solutions and advantages of the present application clearer, further detailed description will be made to the embodiments of the present application in conjunction with the drawings.

[0070] The following detailed description of the embodiments of the present application is not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0071] In the description of the present application, it should be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance. The above terms can be understood by those of ordinary skill in the art in the light of the specific context in which they are used. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The term "and / or", which describes the association relationship between the associated objects, means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0072] 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 the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0073] The present application proposes a dishwasher 1 which can effectively remove food residues on the surface of tableware (bowls, plates, etc.), disinfect and sterilize the tableware during the cleaning process, and dry the tableware after the cleaning and disinfection are completed. Among them, disinfection and sterilization can add cleaning liquid to the water for cleaning tableware, and control the internal environment (including the water temperature of the cleaning liquid) of the dishwasher 1 to be around 70℃-85℃. At this temperature, the activity of common pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus will be inhibited or even killed, thereby ensuring the hygiene of the tableware. The drying method of the dishwasher 1 can be heat exchange drying, hot air drying, etc., which can effectively prevent the tableware from breeding bacteria and producing odor due to moisture.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] On the other hand, the independent upper washing cavity 1531 and lower washing cavity 1532 make the cleaning process clearer. During the washing process, the two washing cavities can work in parallel, shortening the overall washing time. Moreover, when one washing cavity fails or needs maintenance, the other washing cavity can still be used normally, without affecting the user's daily dish cleaning needs.

[0079] In the embodiment, specifically please combine Figures 1 to 8 As shown in the drawings, the inner container 15 includes an upper inner container 151 and a lower inner container 152, wherein the upper inner container 151 includes an upper main body 1511 having an upper inner container top wall 15111, an upper inner container back wall 15112, and two upper inner container side walls 15113, which are oppositely arranged and vertically connected to the upper inner container top wall 15111, forming a U-shaped workpiece. As shown in the drawings, Figure 1 and Figure 2 The upper inner container top wall 15111 is preferably integrally formed with the two upper inner container side walls 15113, and the upper inner container back wall 15112 is preferably integrally formed with the upper inner container top wall 15111 and fixedly connected to the upper inner container side wall 15113.

[0080] In this way, the connection points between the workpieces can be reduced, the continuity is better, and the overall structural strength of the upper inner container 151 is higher. During long-term use of the dishwasher 1, it can better withstand the internal water pressure and external forces such as possible collisions, reducing the risk of damage such as cracking and deformation. It also helps to ensure the sealing of the upper inner container 151 and effectively prevent the risk of water leakage from the joint, thereby improving the reliability and service life of the inner container 15 and the dishwasher 1, reducing the failure and maintenance costs caused by water leakage. At the same time, the use of an integral molding process can also simplify the production process, improve production efficiency and processing precision, and reduce labor and material costs during production. In addition, the integrally formed upper inner container 151 has a smoother surface, reducing the joint gap, and food residues are less likely to accumulate in the gap when cleaning the upper inner container 151, not only reducing the cleaning difficulty, but also preventing the risk of bacteria and mold breeding in the gap, thereby ensuring the dishwasher 1 and ensuring that the cleaned dishes are more hygienic.

[0081] 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.

[0082] 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 2 As 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.

[0083] 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.

[0084] In addition to the following manner, the lower inner container back wall 15212 can be integrally formed with one of the lower inner container side walls 15213, and fixedly connected with the lower inner container top wall 15211 and the lower inner container bottom wall 15214, which can ensure the overall structural strength and stability of the lower inner container 152, and has production process and cost advantages. It should be noted here that the lower inner container top wall 15211, the lower inner container bottom wall 15214 and the two lower inner container side walls 15213 are fixedly connected with the lower inner container back wall 15212. The fixed connection here should be understood as that the lower inner container back wall 15212, the lower inner container top wall 15211, the lower inner container bottom wall 15214 and the two lower inner container side walls 15213 are separately formed workpieces, which is beneficial to fine processing and quality control of each separate workpiece, and makes the production process and assembly process more flexible. In the assembly process, the lower inner container back wall 15212, the lower inner container top wall 15211, the lower inner container bottom wall 15214 and the two lower inner container side walls 15213 are first engaged and spliced, and then welded or riveted, and sealed by gluing. In actual production process, considering factors such as production difficulty, production demand and production cost, the splicing and assembly and the integral forming are combined for production and manufacturing.

[0085] In summary, the U-shaped upper inner container 151 is stacked and installed on the top of the mouth-shaped lower inner container 152, so that the upper inner container 151 and the lower inner container 152 can be independently processed during production, and only need to be assembled later to form the upper washing cavity 1531 and the lower washing cavity 1532 to meet the different use requirements of users. This stacking and installation method is relatively simple, which can well avoid complex internal structure assembly, reduce assembly steps and difficulty, and improve production convenience and efficiency, thereby solving the problem of complex overall structure of the existing upper and lower cavity type dishwasher 1 which leads to complicated assembly, and the simple overall structure is also beneficial to reducing the manufacturing cost.

[0086] As shown in Figure 2 , one of the two upper inner container side walls 15113 is defined as an upper left side wall, and the other is an upper right side wall. One of the two lower inner container side walls 15213 is defined as a lower left side wall, and the other is a lower right side wall. The upper left side wall and the lower left side wall are coplanarly arranged, and the upper right side wall and the lower right side wall are coplanarly arranged. The coplanar arrangement here means that they are in the same plane, specifically, in the up-down direction, the upper left side wall and the lower left side wall are in the same plane, and the upper right side wall and the lower right side wall are in the same plane.

[0087] In this way, the upper inner container 151 and the lower inner container 152 can better support each other at the connecting portion 1683, thereby enhancing the stability and firmness of the structure of the inner container 15 of the dishwasher 1 and reducing the possibility of deformation or damage caused by vibration during washing. At the same time, during assembly, the alignment and connection of the upper inner container 151 and the lower inner container 152 are facilitated, thereby reducing the difficulty and precision requirements of assembly and improving the assembly efficiency. In addition, the side lines of the dishwasher 1 are smoother and neater, thereby improving the overall aesthetics and meeting the aesthetic needs of users for product appearance design.

[0088] Of course, as shown in Figure 1 and Figure 2 , the upper inner container back wall 15112 and the lower inner container back wall 15212 are preferably coplanar, which further ensures the structural strength, stability and sealing performance of the dishwasher 1, facilitates positioning and docking during assembly, and further improves the efficiency during assembly. In addition, it also provides more regular space for the layout of other components inside the dishwasher 1, such as heating devices and drainage pipes, which is conducive to optimizing the internal structure design and making the installation and arrangement of components more reasonable, thereby improving the overall performance and reliability of the dishwasher 1.

[0089] Preferably, as shown in Figure 12 , the upper inner container back wall 15112 and / or the upper inner container side wall 15113 is bent upward to form an upper bent edge 15116, which abuts against the lower inner container top wall 15211. Specifically, the upper bent edge 15116 is parallel to the lower inner container top wall 15211, such that the upper bent edge 15116 is completely attached to the lower inner container top wall 15211 and is welded or glued to the lower inner container top wall 15211. In this way, the contact area / stress area between the upper inner container 151 and the lower inner container top wall 15211 is increased, so that the pressure can be more evenly distributed to the lower inner container top wall 15211 through the upper bent edge 15116, thereby absorbing and dispersing the vibration energy generated during cleaning of tableware to some extent, relieving the stress caused by vibration and improving the stability of the dishwasher 1. At the same time, the upper bent edge 15116 can also serve as a reinforcing structure for the edge of the upper inner container 151. When the dishwasher 1 is subjected to external force (such as collision, torsion caused by placement on uneven surface, etc.), the upper bent edge 15116 can increase the overall rigidity of the upper inner container 151 to resist deformation caused by external force. The upper bent edge 15116 transmits the external force to the entire structure of the lower inner container 152 through the connection with the lower inner container top wall 15211, and utilizes the structural strength of the lower inner container 152 to jointly resist the external force, thereby protecting the structural integrity of the upper inner container 151 and the entire dishwasher 1.

[0090] In addition, the upper bending edge 15116 is connected with the lower inner container top wall 15211 and is sealed by glue or welding, which can effectively fill the gap between the upper inner container 151 and the lower inner container 152, form a good sealing structure, and effectively prevent the risk of leakage between the upper inner container 151 and the lower inner container 152.

[0091] Further, please refer to Figure 12 The length a of the upper bending edge 15116 extending towards the upper washing cavity 1531 is greater than or equal to 3mm, so as to ensure that the upper bending edge 15116 and the lower inner container top wall 15211 have sufficient connection area, no matter whether welding or gluing is used, the larger connection area means that it can withstand greater tension and shear force, so that the connection between the upper inner container 151 and the lower inner container 152 is more stable, and at the same time, the external force can be more evenly dispersed to a larger area. In this way, the dishwasher 1 can better resist various external forces during operation, reducing the possibility of loosening or damage of the connection part 1683 due to vibration, collision, etc. In addition, it can also better ensure the sealing between the upper inner container 151 and the lower inner container 152, that is, when the upper bending edge 15116 extends for a long time, it can better adapt to the gap changes between the upper inner container 151 and the lower inner container 152 due to manufacturing precision, material deformation, etc., so that the glue or welding can more effectively fill the gap to ensure the sealing effect.

[0092] However, if the length a of the upper bending edge 15116 extending is less than 3mm, since the connection area between the upper bending edge 15116 and the lower inner container top wall 15211 is too small, it cannot ensure the structural stability and sealing effect as described above, and at the same time, since the extension length of the upper bending edge 15116 is too short, it may not be smooth during bending due to insufficient operation space, affecting the appearance and dimensional accuracy of the product.

[0093] It should be noted that the specific embodiments are described in combination with Figures 1 to 11As shown, the dishwasher 1 further comprises a water cup 17 having a collection groove 171 capable of communicating with the upper washing cavity 1531, the water cup 17 is assembled to the lower inner container top wall 15211, and the collection groove 171 is used to collect the sewage produced by the upper washing cavity 1531 and output outside the upper washing cavity 1531, that is, the sewage after washing the tableware can be collected into the collection groove 171. Further, the groove bottom of the collection groove 171 is provided with a drainage port, and the sewage collected in the collection groove 171 will be discharged outside the upper washing cavity 1531 through the drainage port. Preferably, the collection groove 171 can also be assembled with a filter element 101 (such as a filter screen, a filter cover, etc.), on the one hand, during the washing process, food residues, grease, debris and other impurities will fall off the tableware into the washing water. The filter element 101 can effectively intercept these impurities to prevent them from clogging the drain pipe connected with the drainage port or entering other components of the dishwasher 1. On the other hand, the filter element 101 can separate the impurities generated during the washing process from the washing water in time, so that the washing water used in circulation can be kept relatively clean. Clean washing water can better play the role of detergent, improve the washing effect, avoid impurities from re-attaching to the tableware, and ensure that the tableware can be thoroughly washed.

[0094] Further, the lower inner container top wall 15211 is provided with a drain groove 164, and the collection groove 171 is located at the inner bottom of the drain groove 164, and the drain groove 164 is used to guide the sewage to the collection groove 171, so that the sewage can flow to the collection groove 171 more quickly and smoothly, and prevent the sewage from flowing randomly, accumulating, and backflowing. It can be understood that the inner bottom surface of the drain groove 164 can be an arc curved surface, or the inner bottom surface is composed of a plurality of inclined planes, and the collection groove 171 is located at the lowest position of the drain groove 164, thereby greatly improving the drainage efficiency, reducing the residence time of the sewage in the upper washing cavity 1531, and reducing the risk of secondary pollution of the tableware.

[0095] In order to realize independent cleaning of the tableware in the upper washing cavity 1531 and the lower washing cavity 1532, please refer to the description of the upper washing cavity 1531 and the lower washing cavity 1532. Figures 1 to 11As shown, the upper washing cavity 1531 and the lower washing cavity 1532 are both provided with the spraying device 102. The spraying device 102 installed in the upper washing cavity 1531 is defined as the first spraying member, and the spraying device 102 installed in the lower washing cavity 1532 is defined as the second spraying member, and the first spraying member and the second spraying member are connected in parallel. Since the first spraying member and the second spraying member can wash independently without interference, this provides users with personalized washing options. Users can set different washing programs according to the dirtiness of the tableware. For example, the upper washing cavity 1531 where the greasy tableware is located can select a strong cleaning mode, and the lower washing cavity 1532 where the relatively clean cups are located can select a fast cleaning mode, thereby improving the washing efficiency and pertinence. Or it also allows users to operate different washing cavities at different times. It should be noted that the first spraying member and the second spraying member belong to mature prior art in the art, and their specific structure and connection relationship are not described here. In addition, the number of the first spraying member and the second spraying member is not limited by the present application, and can be set and adjusted according to design requirements and structural design.

[0096] In addition to the above, the washing inner cavity 153 is divided into relatively independent upper washing cavity 1531 and lower washing cavity 1532 by the lower inner container top wall 15211 of the lower inner container 152, the inventor also provides another preferred embodiment, please combine Figure 3 and Figure 4 As shown, the dishwasher 1 further comprises a partition piece 16, and the above-mentioned lower inner container top wall 15211 is formed as the partition piece 16, that is, the lower inner container top wall 15211 is formed as a separately formed workpiece, and the partition piece 16 is provided with a first insertion slot 13 opening upward and a second insertion slot 14 opening downward, and the first insertion slot 13 and the second insertion slot 14 are both preferably arranged at the edge position of the partition piece 16.

[0097] As can be understood, as Figure 10 shown, the above-mentioned water cup 17 is assembled on the partition piece 16. Not only is it convenient for the installation of the water cup 17, but it is also beneficial for the subsequent inspection, replacement and maintenance of the water cup 17, reducing the difficulty and time cost of maintenance. At the same time, it is also beneficial for cleaning the water cup 17 and maintaining the overall hygiene of the dishwasher 1.

[0098] Further, as Figure 3As shown, the upper inner container 151 and the lower inner container 152 are respectively arranged on the upper and lower sides of the partition 16, and the upper inner container 151 is provided with the first plug-in part 11, and the lower inner container 152 is provided with the second plug-in part 12. The first plug-in part 11 is preferably arranged on the upper inner container back wall 15112 and / or the upper inner container side wall 15113, and the second plug-in part 12 is preferably arranged on the lower inner container back wall 15212 and / or the lower inner container side wall 15213. Then, during assembly, the first plug-in part 11 is plugged into the first slot 13, and the upper inner container 151 is formed with the partition 16 into the upper washing cavity 1531, and the second plug-in part 12 is plugged into the second slot 14, and the lower inner container 152 is formed with the partition 16 into the lower washing cavity 1532. The upper washing cavity 1531 and the lower washing cavity 1532 are relatively independent.

[0099] Thus, the following unexpected technical effects can be achieved:

[0100] 1. The upper inner container 151 and the lower inner container 152 are respectively plugged into the partition 16, which simplifies the assembly process, reduces the assembly difficulty and the requirement for worker skills. Compared with complex welding, riveting and other connection methods, the assembly speed can be improved, and the assembly time and labor cost can be reduced. During the assembly process or the replacement process in the later maintenance, the upper inner container 151 or the lower inner container 152 can be separated from the partition 16 more conveniently, which reduces the disassembly and assembly difficulty and the maintenance difficulty, thereby reducing the assembly cost and the maintenance cost.

[0101] 2. The plug-in assembly method helps to improve the assembly precision. The first slot 13 and the second slot 14 can be used as positioning structures to guide the accurate installation of the upper inner container 151 and the lower inner container 152 to the two sides of the partition 16, so as to ensure the position precision and structural stability of the upper washing cavity 1531 and the lower washing cavity 1532. Such accurate assembly method can reduce quality problems caused by improper assembly, such as poor sealing of the washing cavity, deviation of the water spraying angle of the spraying device 102, etc., thereby improving the quality stability of the product.

[0102] As a preferred mode of the embodiment, the specific structure of the first plug-in part 11 and the second plug-in part 12 can be determined according to the specific structure of the first slot 13 and the second slot 14. Figure 14 As shown, the first plug-in part 11 comprises a first extension body 111 and a first bending part 112 bent and formed at the end of the first extension body 111, and the first extension body 111 is fixedly connected to the upper inner container back wall 15112 and / or the upper inner container side wall 15113 of the upper inner container 151, which is preferably achieved by an integral molding process. The first extension body 111 and the first bending part 112 cooperate to form a U-shaped structure. The first extension body 111 and the first bending part 112 respectively abut against two opposite slot walls of the first slot 13, so that the first plug-in part 11 can be tightly fitted with the first slot 13.

[0103] Thus, the stability of the connection between the upper inner container 151 and the partition 16 is greatly enhanced, the insertion is firm, and the upper inner container 151 is prevented from being displaced during long-term use of the dishwasher 1. Meanwhile, the first extension 111 and the first bent portion 112 are in close contact with the inner groove walls of the first insertion slot 13, which effectively fills the gap between the insertion slot and the insertion portion, prevents the washing water from leaking out of the upper washing cavity 1531, and prevents foreign matter such as food residue from entering the gap between the insertion slot and the insertion portion, thereby achieving good sealing effect. In addition, the first extension 111 and the first bent portion 112 of the first insertion portion 11 are formed by bending, and the stamping and bending operation can be performed by using a mold on the production line, which facilitates processing and manufacturing and improves production efficiency.

[0104] Preferably, the second insertion portion 12 includes a second extension 121 and a second bent portion 122 bent on an end of the second extension 121, and the second extension 121 is fixedly connected to the lower inner container back wall 15212 and / or the lower inner container side wall 15213 of the lower inner container 152, preferably by an integral molding process. The second extension 121 and the second bent portion 122 cooperate to form a U-shaped structure. The second extension 121 and the second bent portion 122 are in abutment with two opposite inner groove walls of the second insertion slot 14, so that the second insertion portion 12 can be tightly fitted with the second insertion slot 14.

[0105] Thus, the stability of the connection between the upper inner container 151 and the partition 16 is greatly enhanced, the insertion is firm, and the upper inner container 151 is prevented from being displaced during long-term use of the dishwasher 1. Meanwhile, the first extension 111 and the first bent portion 112 are in close contact with the inner groove walls of the first insertion slot 13, which effectively fills the gap between the insertion slot and the insertion portion, prevents the washing water from leaking out of the upper washing cavity 1531, and prevents foreign matter such as food residue from entering the gap between the insertion slot and the insertion portion, thereby achieving good sealing effect. In addition, the first extension 111 and the first bent portion 112 of the first insertion portion 11 are formed by bending, and the stamping and bending operation can be performed by using a mold on the production line, which facilitates processing and manufacturing and improves production efficiency.

[0106] Further, the specific embodiments are described below Figure 4As shown, in the first slot 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 height of the abutting assembly between the first bending portion 112 of the first plug-in portion 11 and the first slot 13 is greater than or equal to 4 mm. At this time, the stress area between the first bending portion 112 and the first slot 13 is larger, 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 force or pushing force may be generated on the upper inner container 151, or during the washing process, due to the reaction force of water spraying and the action force caused by the shaking of tableware, a longer abutting height / larger stress area can provide greater friction and support, making the connection between the upper inner container 151 and the partition 16 more stable, reducing the risk of connection loosening due to external forces. And in the process of long-term use, enough abutting height can ensure that even in the case of a certain degree of fatigue of the first plug-in portion 11, the connection between the upper inner container 151 and the partition 16 is still reliable, maintaining the normal structure and function of the upper washing cavity 1531.

[0107] In addition, a larger abutting height helps to form a more reliable seal. When the dishwasher 1 is working, the washing cavity will be filled with high-pressure water and detergent mixture, and these liquids need to be confined in the washing cavity. When the abutting height of the first bending portion 112 is sufficient, it can be more closely attached to the inner wall of the first slot 13, effectively preventing liquid from leaking from the connection between the upper inner container 151 and the partition 16. It can also reduce the possibility of foreign matter (such as food residue) entering the joint gap to some extent. If the gap is too large or the abutting height is insufficient, foreign matter may be washed into the gap during the washing process, affecting the sealing effect and possibly causing blockage or corrosion. An abutting height greater than or equal to 4 mm can form a relatively deep sealing structure, reducing this risk.

[0108] Of course, during assembly, when the first bending length Lt1 is greater than or equal to 4 mm, the first bending length Lt1 is longer and can serve as a good positioning guide structure, facilitating positioning and calibration during assembly, that is, during insertion, more accurate position adjustment can be made according to the contact with the inner wall of the first slot 13, which helps to improve the accuracy and efficiency of assembly.

[0109] On the contrary, when the first bending length Lt1 is less than 4 mm, the height of the abutting assembly between the first bending part 112 and the first slot 13 will also be less than 4 mm, and the stress area is small. When facing external forces during the operation of the dishwasher 1, the connection structure may become unstable and cannot provide sufficient friction and support. It is also not conducive to forming a good seal. During the washing process, especially under high water pressure, liquid is more likely to leak from the connection gap. Once leakage occurs, not only will it affect the washing effect of the dishwasher 1, but it may also cause damage to other electrical components of the dishwasher 1, causing safety hazards.

[0110] Preferably, in the second slot depth direction T2 of the second slot 14, the second bending length Lt2 of the second bending part 122 is greater than or equal to 4 mm, that is, the second bending part 122 is located inside the second slot 14, and the height of the abutting assembly between the second bending part 122 of the second plug-in part 12 and the second slot 14 is greater than or equal to 4 mm. At this time, the stress area between the second bending part 122 and the second slot 14 is larger, and during the operation of the dishwasher 1, it can better resist various external forces and reduce the risk of connection loosening caused by external forces. And in the process of long-term use, enough abutting height can ensure that even if the second plug-in part 12 appears a certain degree of fatigue, the connection between the lower inner container 152 and the partition 16 is still reliable, maintaining the normal structure and function of the lower washing cavity 1532.

[0111] In addition, a larger abutting height helps to form a more reliable seal. When the dishwasher 1 is working, the washing cavity will be filled with high-pressure water and detergent mixture, and these liquids need to be confined in the washing cavity. When the abutting height of the second bending part 122 is sufficient, it can be more closely fitted to the inner wall of the second slot 14, effectively preventing liquid from leaking from the connection between the lower inner container 152 and the partition 16. It can also reduce the possibility of foreign matter entering the connection gap to some extent. If the gap is too large or the abutting height is insufficient, foreign matter may be washed into the gap during the washing process, affecting the sealing effect and possibly causing blockage or corrosion. An abutting height greater than or equal to 4 mm can form a relatively deep sealing structure, reducing this risk.

[0112] Of course, during assembly, when the second bending length Lt2 is greater than or equal to 4 mm, the second bending length Lt2 is longer and can serve as a good positioning guide structure, facilitating positioning and calibration during assembly. That is, during insertion, more accurate position adjustment can be made according to the contact with the inner wall of the second slot 14, which helps to improve the accuracy and efficiency of assembly.

[0113] On the contrary, when the second bending length Lt2 is less than 4 mm, the height of the abutting assembly between the second bending part 122 and the second slot 14 will also be less than 4 mm, and the stress area is small. When facing external force during the operation of the dishwasher 1, the connection structure may become unstable and cannot provide sufficient friction and support. It is also not conducive to forming a good seal. During the washing process, especially under high water pressure, liquid is more likely to leak from the connection gap. Once the leakage occurs, not only will it affect the washing effect of the dishwasher 1, but it may also cause damage to other electrical components of the dishwasher 1, causing safety hazards.

[0114] In other embodiments, the first plug-in part 11 includes a first extension body 111 and a first bending part bent and formed at the end of the first extension body 111, and the first bending part is bent and protrudes towards the inner slot wall of the first slot 13. The number of first bending parts here is set and adjusted according to the structure design or design requirements, and the first extension body 111 and the first bending part abut the slot wall of the first slot 13, respectively, which can achieve the purpose of stable assembly and good sealing performance. Similarly, the second plug-in part 12 includes a second extension body 121 and a second bending part bent and formed at the end of the second extension body 121, and the second bending part is bent and protrudes towards the inner slot wall of the second slot 14. The number of second bending parts here is set and adjusted according to the structure design or design requirements, and the second extension body 121 and the second bending part abut the inner slot wall of the second slot 14, respectively, which can achieve the purpose of stable assembly and good sealing performance.

[0115] It should be noted that the bending part and the bending part provided above are used in combination, for example, the first bending part 112 bent and formed at the end of the first extension body 111 in the first plug-in part 11, and the second bending part bent and formed at the end of the second extension body 121 in the second plug-in part 12. For another example, the first bending part bent and formed at the end of the first extension body 111 in the first plug-in part 11 is a first bending part, and the second plug-in part 12 bent and formed at the end of the second extension body 121 is a second bending part. For another example, the first bending part bent and formed at the end of the first extension body 111 in the first plug-in part 11 is a first bending part, and the second plug-in part 12 bent and formed at the end of the second extension body 121 is a second bending part. For another example, the first bending part bent and formed at the end of the first extension body 111 in the first plug-in part 11 is a first bending part, and the first bending part is bent and arranged between the first extension body 111 and the first bending part 112. Alternatively, the first plug-in part 11 and the second plug-in part 12 are both shaped as a U-shaped bending part. Of course, the first plug-in part 11 and the second plug-in part 12 are both shaped as a bending part.

[0116] As a preferred way of the present embodiment, please refer to Figure 13As shown, the partition 16 comprises a first inner side wall 1611 and a first outer side wall 1612, wherein the first inner side wall 1611 is located on the side close to the upper washing cavity 1531, and the first outer side wall 1612 is located on the side away from the upper washing cavity 1531 and is arranged opposite to the first inner side wall 1611 to form the first insertion slot 13, and the height dimension of the first inner side wall 1611 is smaller than that of the first outer side wall 1612, that is, a height difference is formed between the first inner side wall 1611 and the first outer side wall 1612.

[0117] In this way, the higher first outer side wall 1612 can form a relatively higher blocking structure on the side away from the upper washing cavity 1531. When the dishwasher 1 is working, even if a small amount of washing water seeps from the connection between the first insertion part 11 and the first insertion slot 13, it will be blocked by the higher first outer side wall 1612 and is not easy to flow out of the washing cavity directly, but a relatively static water sealing area is formed in the first insertion slot 13, which further prevents water from continuing to seep outwards, achieving the purpose of sealing and preventing water leakage. At the same time, the height dimension of the first inner side wall 1611 is relatively small and close to the side of the upper washing cavity 1531, so that the water flow is more likely to flow back to the upper washing cavity 1531 along the connection between the first insertion part 11 and the first insertion slot 13 under the action of gravity and the internal pressure of the washing cavity, rather than accumulating at the connection to cause leakage.

[0118] Further, as shown in Figure 15 The first extension body 111 abuts against the first inner side wall 1611, and the first bending part 112 abuts against the first outer side wall 1612. At this time, the first extension body 111 abutting against the first inner side wall 1611 will form the first sealing line, which can preliminarily block the water from flowing into the first insertion slot 13 from the gap between the first insertion part 11 and the first outer side wall 1612. The first bending part 112 abutting against the first outer side wall 1612 is equivalent to the second sealing line. Even if a small amount of water breaks through the first sealing line, it will be blocked by the second sealing line. In combination with the height difference formed between the first inner side wall 1611 and the first outer side wall 1612, three sealing lines will be formed, which can effectively reduce the risk of water seeping outwards.

[0119] As a preferred mode of the present embodiment, specifically, as shown in Figure 14 and Figure 15 The partition 16 comprises a second inner side wall 1621 and a second outer side wall 1622, wherein the second inner side wall 1621 is located on the side close to the lower washing cavity 1532, and the second outer side wall 1622 is located on the side away from the lower washing cavity 1532 and is arranged opposite to the second inner side wall 1621 to form the second insertion slot 14, and the height dimension of the second inner side wall 1621 is greater than that of the second outer side wall 1622.

[0120] In this way, the higher second inner side wall 1621 can form a relatively high barrier on the side close to the lower washing cavity 1532. When the water in the washing cavity has a tendency to leak out due to various reasons (such as water flow impact during washing, water splashing caused by improper placement of tableware, etc.), it will first encounter the blocking of the second inner side wall 1621. The water flow needs to overcome a certain height difference to cross the second inner side wall 1621, which increases the difficulty of water leakage and plays a blocking role. When a small amount of water seeps into the gap between the second inner side wall 1621 and the second insertion part 12, under the action of gravity, water will more easily accumulate between the second inner side wall 1621 and the second insertion part 12 to form a certain water seal effect. This part of the accumulated water can further prevent subsequent water leakage that may occur, because water will naturally fill the gaps and channels that may exist under the action of gravity, forming a water barrier to prevent water in the washing cavity from continuing to leak out. Therefore, the height dimension of the second inner side wall 1621 is greater than the height dimension of the second outer side wall 1622, which can effectively prevent the risk of leakage at the position connecting the lower inner container 152 and the partition 16.

[0121] Further, as shown in FIG. 12, Figure 13 The second extension body 121 abuts against the second inner side wall 1621, and the second bending part 122 abuts against the second outer side wall 1622. In this way, the second extension body 121 abuts against the second inner side wall 1621 with a larger area, which not only better ensures that the position connecting the lower inner container 152 and the partition 16 will not have the risk of leakage. At the same time, it also enables the lower inner container 152 and the partition 16 to be more uniformly stressed, reducing the risk of structural damage or deformation due to local stress concentration, thereby improving the stability and reliability of the entire structure.

[0122] It should be noted that the height difference between the first inner side wall 1611 and the first outer side wall 1612 is a first height difference ΔHx1, and the first height difference ΔHx1≥3mm. The height difference between the second inner side wall 1621 and the second outer side wall 1622 is a second height difference ΔHx2, and the second height difference ΔHx2≥0.

[0123] In which, the height dimension of the first inner side wall 1611 is defined as a first inner height Hn1, and the first inner height Hn1≥5mm, which can effectively ensure that the first insertion slot 13 and the first insertion part 11 are reliably assembled, preventing the upper washing cavity 1531 from being assembled out of position and deformed. The height dimension of the second inner side wall 1621 is defined as a second inner height Hn2, and the second inner height Hn2≥5mm, which not only can effectively ensure that the second insertion slot 14 and the second insertion part 12 are reliably assembled, preventing the lower washing cavity 1532 from being assembled out of position and deformed. At the same time, it also plays an effective water leakage prevention role to some extent.

[0124] Preferably, please combine the specific Figures 3 to 5 As shown, the first inner side wall 1611 is provided with a flow guide slope 1633 on the side close to the upper washing cavity 1531, and the flow guide slope 1633 is inclined to the first inner side wall 1611. Specifically, the flow guide slope 1633 is arranged to be inclined downward along the direction close to the center of the upper inner container 151. The flow guide slope 1633 here is preferably a plane, that is, the flow guide slope 1633 is in a chamfer structure. Of course, the flow guide slope 1633 can also be selected to be an arc surface arranged protruding, that is, the flow guide slope 1633 is in a rounded chamfer structure. Alternatively, the flow guide slope 1633 can also be selected to be an arc surface arranged concave.

[0125] In this way, under the action of the flow guide slope 1633, the water flow flows along the inclined direction of the flow guide slope 1633, avoiding irregular splashing or directly vertically downward flow, which helps to more concentratedly guide the water flow to a specific position. At the same time, during the operation of the dishwasher 1, a large amount of water vapor will be generated inside, and the inclined flow guide slope 1633 can make the condensed water vapor be more quickly concentrated and guided to a specific position on the partition 16, avoiding irregular condensation of water vapor on the first inner side wall 1611 to form water droplets, and also accelerating the drainage speed, which not only reduces the problem of moisture inside the dishwasher 1 caused by water vapor condensation, but also helps to shorten the duration of the humid environment inside the upper washing cavity 1531 and maintain a dry environment inside the upper washing cavity 1531, reducing the problems of component corrosion and mold caused by moisture, and also reducing the water accumulation time in the washing cavity, which is beneficial to improve the overall working efficiency of the dishwasher 1, especially in the drainage stage, the drainage operation can be completed faster, saving time for subsequent rinsing, drying and other processes, and improving the reliability and stability of the dishwasher 1.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] It should be noted that, please refer to Figure 15The interval between the two adjacent reinforcing walls 1631 is the distribution interval L. It can be understood that the interval between the center lines of the two reinforcing walls 1631 is the distribution interval L, and the distribution interval L is greater than or equal to 10 mm. According to the above-mentioned insertion principle between the first insertion part 11 and the first insertion slot 13, the distribution interval L greater than or equal to 10 mm will effectively provide assembly limiting and increase assembly reliability. When the distribution interval L is less than 10 mm, the interval between the two adjacent reinforcing walls 1631 is small, and the requirement for machining precision during mold processing is significantly increased. The tool path planning, cutting parameter selection, etc. become more difficult, and more precise machining equipment and more advanced machining processes are required. In addition, the performance requirements for the strength, hardness and wear resistance of the mold material are also higher, thereby leading to the complication of the mold and increasing the production cost of the partition piece 16.

[0130] In addition to the above-mentioned manner that the upper liner 151 and the lower liner 152 are respectively provided with the first insertion part 11 and the second insertion part 12, and the partition piece 16 is provided with the first insertion slot 13 for inserting the first insertion part 11 and the second insertion slot 14 for inserting the second insertion part 12, the inventor also provides another preferred embodiment, which is specifically described in combination with Figure 5 and Figure 6 As shown in the figures, the upper and lower sides of the partition piece 16 are respectively provided with the first insertion part 11 and the second insertion part 12, and the first insertion part 11 and the second insertion part 12 are preferably arranged at the edge position of the partition piece 16. The upper liner 151 is provided with a downwardly opening first insertion slot 13, the first insertion part 11 is inserted into the first insertion slot 13, the lower liner 152 is provided with an upwardly opening second insertion slot 14, and the second insertion part 12 is inserted into the second insertion slot 14. During assembly, the upper liner 151 and the lower liner 152 are arranged at the upper and lower sides of the partition piece 16, respectively, and the upper liner 151 and the partition piece 16 are configured to form an upper washing cavity 1531, and the lower liner 152 and the partition piece 16 are configured to form a lower washing cavity 1532. The upper washing cavity 1531 and the lower washing cavity 1532 are relatively independent.

[0131] By such an arrangement, the following unexpected technical effects can be achieved:

[0132] 1. The upper liner 151 and the lower liner 152 are respectively inserted and assembled with the partition piece 16, which simplifies the assembly process, reduces the assembly difficulty and the requirement for worker skills. Compared with the complex welding, riveting and other connection methods, the assembly speed can be improved, and the assembly time and labor cost can be reduced. During the assembly process or the replacement process in the later maintenance, the upper liner 151 or the lower liner 152 can be separated from the partition piece 16 more conveniently, thereby reducing the disassembly and assembly difficulty and the maintenance difficulty, and reducing the assembly cost and the maintenance cost.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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:

[0138] 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.

[0139] 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.

[0140] For further details, please refer to [link / reference]. Figure 17The distance between the end of the upper bent side wall 15115 close to the partition 16 and the end of the upper bent top wall 15114 away from the partition 16 along the first slot depth direction T1 of the first slot 13 is the upper assembly height h1. The first plug-in part 11 protrudes in a direction perpendicular to the partition 16 by a first height H1, and the upper assembly height h1 is greater than the first height H1.

[0141] In this way, the upper assembly height h1 is large, and a relatively tortuous path is formed at the plug-in fit between the first plug-in part 11 and the first slot 13. This tortuous path can increase the resistance of water during flow, so that it is more difficult for water in the washing cavity to leak out of this fit gap. Even if a small amount of water penetrates into the fit gap, it needs to pass through a longer path to reach the outside, greatly reducing the possibility of water leakage. At the same time, it can effectively prevent water from moving between different washing cavities, improving the sealing and stability of the structure. In addition, the larger upper assembly height h1 provides more operating space for the insertion of the first plug-in part 11 into the first slot 13. Assembly personnel can more easily align the first plug-in part 11 with the first slot 13, and even if there is a certain deviation during assembly, there is enough space for fine adjustment, so that the first plug-in part 11 can be accurately inserted into the appropriate position, reducing the assembly difficulty and improving the positioning efficiency and assembly efficiency.

[0142] Preferably, the first height H1 is greater than or equal to 3 mm. This not only makes the contact area between the first plug-in part 11 and the first slot 13 sufficient. During assembly, a larger contact area means that the friction increases, which helps the first plug-in part 11 to be inserted more stably into the first slot 13 and not easy to loosen. This makes the connection between the upper inner container 151 and the partition 16 more tight and reliable, ensuring the stability and assembly reliability of the entire dishwasher 1 structure, so as to better resist the influence of factors such as vibration and water flow impact during the operation of the dishwasher 1, reducing or even avoiding the risk of displacement or falling between components due to loose connection, and providing a more explicit guide and positioning function for assembly, more effectively correcting possible minor deviations, ensuring the relative position of the upper inner container 151 and the partition 16 is accurate, thereby improving the precision and quality of assembly.

[0143] At the same time, when the first height H1 is greater than or equal to 3 mm, a long enough path is formed at the fit between the first plug-in part 11 and the first slot 13. Water needs to overcome a longer distance and greater resistance to leak out of the upper washing cavity 1531, increasing the difficulty of water leakage, effectively preventing water from escaping or leaking to the outside of the dishwasher 1, ensuring the waterproof performance of the dishwasher 1, protecting the electrical elements inside the dishwasher 1, and prolonging the service life of the dishwasher 1.

[0144] In addition, the first height H1≥3mm provides sufficient operation space for sheet metal bending. During the bending process, the larger height can make the sheet metal more easily bent into the required shape, more conducive to the sheet metal forming of the inner liner 151, reduces the risk of material cracking or deformation due to too small bending radius, and is conducive to ensuring the accuracy and quality of the bending, so that the shape and size of the first plug-in part 11 are more in line with the design requirements, and the product qualification rate and production efficiency are improved.

[0145] When the first height H1<3, the contact area between the first plug-in part 11 and the first slot 13 is insufficient, making the connection between the two unstable, and easily loosening during the operation of the dishwasher 1 due to vibration or external force, greatly reducing the assembly reliability. At the same time, the guiding and positioning effect during assembly is weakened, and deviation and misplacement are easily caused. In addition, the waterproof performance is reduced, and water is more likely to leak out from the fit between the first plug-in part 11 and the first slot 13, greatly increasing the possibility of water leakage outside the dishwasher 1.

[0146] As a preferred mode of the present embodiment, please refer to Figure 16 and Figure 17 As shown, the lower inner liner 152 further comprises a lower limiting piece 1522, wherein the lower main body 1521 is bent and formed with a lower bent bottom wall 15215 on one side of the lower washing cavity 1532, and the end of the lower bent bottom wall 15215 is bent and formed with a lower bent side wall 15216 on one side of the partition 16, that is, the end of the lower inner liner side wall 15213 and / or the lower inner liner back wall 15212 close to the partition 16 is bent and formed with the lower bent bottom wall 15215 and the lower bent side wall 15216, and the upper bent side wall 15115 is preferably arranged in a direction perpendicular to the partition 16, and the lower limiting piece 1522 is connected to the lower main body 1521 to cooperate with the lower bent bottom wall 15215 and the lower bent side wall 15216 to form the second slot 14. Here, the cooperation should be understood as that after the lower limiting piece 1522 is attached to the lower main body 1521, at least one of the following processes is used to install and fix it: buckle connection, welding connection, riveting connection, and adhesive connection.

[0147] In this way, compared with the structure of the integrally formed lower inner liner 152, the lower inner liner 152 is divided into the lower main body 1521 and the lower limiting piece 1522 for separate manufacturing, and then assembled, which can reduce the manufacturing difficulty of the lower inner liner 152, improve the production efficiency, and reduce the production cost.

[0148] It should be noted that the lower bent bottom wall 15215 is inclined to the lower limiting piece 1522 and extends towards one side of the partition 16, so that the lower bent bottom wall 15215 is arranged at an angle with the lower limiting piece 1522. The end of the second plug-in part 12 away from the partition 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 arranged 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 piece 1522. Here, the adaptation should be understood as that the two angles are equal or within the assembly tolerance range.

[0149] In this way, the second plug-in part 12 is more accurate in cooperation with the lower inner container 152 during assembly, ensuring the relative position between the lower inner container 152 and the partition 16 is accurate, thereby ensuring the dimensional accuracy and shape accuracy of the lower washing cavity 1532, which is beneficial to improve the assembly quality of the internal structure of the whole dishwasher 1. At the same time, it can also effectively reduce the difficulty of positioning and improve the positioning efficiency. In addition, the close cooperation between the lower positioning part and the lower bent bottom wall 15215 also increases the contact area and friction force between the lower inner container 152 and the partition 16, making the connection between the two more stable and improving the connection strength, which helps to improve the strength and reliability of the whole structure and reduce the risk of component damage due to excessive local stress.

[0150] Of course, specific please combine Figure 16 and Figure 17 It is shown that the lower bent bottom wall 15215 can also be perpendicular to the lower limiting piece 1522, which can also ensure the assembly accuracy and structural stability between the lower inner container 152 and the partition 16. At the same time, the processing and forming are also more simple, which reduces the processing difficulty, thereby being beneficial to reduce the production cost.

[0151] Further, please refer to Figure 17 , along the second slot depth direction T2 of the second slot 14, the distance between the end of the lower bent side wall 15216 close to the partition 16 and the end of the lower bent bottom wall 15215 away from the partition 16 is the lower assembly height h2. Along the direction perpendicular to the partition 16, the height of the second plug-in part 12 protruding is the second height H2, and the lower assembly height h2 is greater than or equal to the second height H2.

[0152] In this way, a relatively tortuous and long path is formed at the joint between the second plug-in part 12 and the second plug-in groove 14. In the operation of the dishwasher 1, if water in the lower washing cavity 15 leaks, it needs to flow along this long path. The water is affected by friction and other resistance in the process of flowing. The longer the path, the greater the resistance, and the more difficult the water leakage. Therefore, the possibility of water leakage from the joint between the second plug-in groove 14 and the second plug-in part 12 to the outside of the dishwasher 1 is greatly reduced, and the water leakage phenomenon is effectively prevented.

[0153] Preferably, the second height H2 is greater than or equal to 3 mm. This not only makes the joint between the second plug-in part 12 and the second plug-in groove 14 form a long enough path. Water needs to overcome a longer distance and greater resistance to leak out of the lower washing cavity 15, increasing the difficulty of water leakage, effectively preventing water from leaking 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 prolonging the service life of the dishwasher 1. At the same time, it also provides enough operation space for sheet metal bending. In the bending process, the larger height can make the sheet metal more easily bent into the required shape, which is more conducive to the sheet metal forming of the lower inner container 152, reduces the risk of material cracking or deformation caused by too small bending radius, and is conducive to ensuring the accuracy and quality of bending. The shape and size of the second plug-in part 12 are more in line with the design requirements, improving the product qualification rate and production efficiency.

[0154] If the second height H2 is less than 3 mm, the contact area between the second plug-in part 12 and the second plug-in groove 14 is insufficient, making the connection between the two unstable and easily loosening due to vibration or external force during the operation of the dishwasher 1. This greatly reduces the assembly reliability of the dishwasher 1. At the same time, it also reduces the waterproof performance, and water can easily leak out from the joint between the second plug-in part 12 and the second plug-in groove 14, greatly increasing the possibility of water leakage outside the dishwasher 1.

[0155] Preferably, as shown in Figs. 16 and Figure 17 Preferably, the first slot width dimension B1 of the first plug-in groove 13 is greater than or equal to the first thickness dimension K1 of the first plug-in part 11 in the first slot width direction Tu of the first plug-in groove 13, and the second slot width dimension B2 of the second plug-in groove 14 is greater than or equal to the second thickness dimension K2 of the second plug-in part 12 in the second slot width direction Tl of the second plug-in groove 14.

[0156] In this way, the larger slot width provides a certain space for the insertion part in the slot, so that fine adjustment can be made during assembly, ensuring that the relative positions between the upper inner container 151, the lower inner container 152 and the partition 16 are accurate. This facilitates the insertion of the first insertion part 11 and the second insertion part 12 into the corresponding slots during assembly, reduces the difficulty of insertion due to dimensional tolerance or slight deviation during assembly, reduces the requirement for the operation accuracy of the assembly workers, and improves the assembly efficiency. At the same time, the requirement for manufacturing accuracy can also be appropriately reduced, the waste rate during manufacturing can be reduced, the production efficiency can be improved, and the production cost can be reduced.

[0157] It should be noted that the first thickness dimension K1 is greater than or equal to 2 mm, and the second thickness dimension K2 is greater than or equal to 2 mm, which can effectively ensure that the first insertion part 11 and the second insertion part 12 have sufficient strength and can withstand various external forces during assembly and use, avoid deformation or damage due to excessive thinness, and ensure that the dishwasher 1 can resist water impact and vibration during use, thereby ensuring the stability and reliability of the dishwasher 1.

[0158] When the first thickness dimension K1 and the second thickness dimension K2 are both less than 2 mm, the structural strength of the first insertion part 11 and the second insertion part 12 will be significantly reduced. During assembly, the thinner insertion part may be deformed, such as bending or breaking, due to the need for external force when inserting into the slot, which may prevent normal assembly. During use of the dishwasher 1, the thinner insertion part is more likely to deform or even be damaged due to water impact, vibration and internal pressure changes, thereby damaging the connection structure between the upper inner container 151, the lower inner container 152 and the partition 16, greatly reducing the stability and sealing performance of the dishwasher 1, and affecting the normal use of the dishwasher 1. At the same time, due to the limited deformation capacity of the thinner first insertion part 11 and the second insertion part 12 when subjected to external forces, cracking and wrinkling are more likely to occur during bending, stamping and other forming processes, thereby increasing the difficulty of forming and the waste rate.

[0159] Further, please refer to 16 and Figure 17As shown, the partition 16 is provided with an embedding slot 165, the slot opening of the embedding slot 165 is downwardly arranged on the side of the lower washing cavity 1532, and the embedding slot 165 is located on the side of the second plug-in part 12 away from the lower limiting part 1522, and the lower bending side wall 15216 can be arranged to extend towards the inside of the embedding slot 165. In this way, the embedding slot 165 and the lower bending side wall 15216 also form a zigzag path by plug-in cooperation, when water tries to leak from the lower washing cavity 1532, it needs to pass a longer distance and more obstacles, further increasing the difficulty of water leakage, effectively preventing the washing liquid from leaking from the connecting part 1683 of the lower inner container 152 and the partition 16 to other parts of the dishwasher 1, and improving the waterproof performance of the dishwasher 1.

[0160] In addition to the above-mentioned way that the upper inner container 151 and the lower inner container 152 are plug-in connected with the partition 16, the inventors also provide another preferred embodiment, please combine with Figure 7 and Figure 8 As shown, the upper inner container side wall 15113 and the lower inner container side wall 15213 are integrally formed into an inner container side wall, which is a separately formed workpiece, i.e., the upper left side wall and the lower left side wall are integrally formed, and the upper right side wall and the lower right side wall are integrally formed. The upper inner container back wall 15112 and the lower inner container back wall 15212 are integrally formed into an inner container back wall, which is a separately formed workpiece. Further, the above-mentioned partition 16 includes a folding part 167, which is sealingly connected with the cavity inner wall of the washing inner cavity 153, i.e., the inner container side wall and the inner container back wall are sealingly connected with the folding part 167, then after assembly, the partition 16 is assembled in the washing inner cavity 153 to separate the washing inner cavity 153 into an upper washing cavity 1531 and a lower washing cavity 1532, the upper washing cavity 1531 and the lower washing cavity 1532 are relatively independent.

[0161] In this way, the following unexpected technical effects will be achieved:

[0162] 1. Compared with the separately formed upper and lower inner containers 152 parts, the integrally formed design can further reduce the connection points and gaps, reduce the probability of weak structure points, thereby better withstand the internal pressure, water flow impact and external collision forces and other forces during the operation of the dishwasher 1, and better maintain the shape during the operation, reduce the deformation caused by vibration or other external forces, improve the overall strength, durability and structural stability of the inner container 15.

[0163] 2. In terms of assembly, it can further simplify the assembly steps, reduce the assembly difficulty, improve the assembly accuracy and efficiency, and reduce the quality problems caused by inaccurate butt joint of parts during assembly. It can also ensure that the partition piece 16 accurately separates the washing inner cavity 153 into relatively independent upper and lower washing cavities 1531 and 1532, avoiding the problems of communication between the two washing cavities or poor sealing caused by assembly errors.

[0164] 3. The integrally formed inner container 15 reduces internal gaps and corners, making it easier to clean the inside of the dishwasher 1. After daily use, users can more conveniently clean the dirt and residues in the upper and lower washing cavities 1531 and 1532, reducing the cleaning difficulty and time cost. In addition, when maintenance is needed, the number of parts is reduced, making it easier for maintenance personnel to locate and handle problems, improving maintenance efficiency.

[0165] It should be noted that the above sealing connection should be understood as the welding connection and / or adhesive connection of the folded part 167 with the inner wall of the washing inner cavity 153. For example, the assembler first accurately places the partition piece 16 in the washing inner cavity 153 at the appropriate position, so that the folded part 167 tightly fits the inner wall. Then, using a laser welding device, the contact edge of the folded part 167 and the inner wall is welded, generating high temperature to fuse the folded part 167 and the inner wall together. In this way, the welding process is fast and accurate, the weld is uniform and beautiful, and the welding strength is high, which can withstand the internal pressure and water flow impact during the operation of the dishwasher 1.

[0166] For example, the assembler first cleans the surface of the folded part 167 and the surface of the inner wall to remove impurities such as oil and dust, to ensure that the sealant can better adhere. Then, use a glue gun to evenly apply the sealant to the contact surface of the folded part 167 and the inner wall. After the application is completed, quickly install the partition piece 16 into the washing inner cavity 153, so that the folded part 167 tightly fits the inner wall, and extrudes the excess sealant. During the curing process of the sealant, an elastic sealing layer is formed to fill the small gap between the folded part 167 and the inner wall. In this way, it can adapt to the slight deformation caused by temperature changes and vibrations during the operation of the dishwasher 1, maintaining good sealing performance. Moreover, this adhesive connection method is relatively simple to operate and has low cost, and it is also convenient to maintain if needed. If the partition piece 16 needs to be replaced or repaired later, the solidified sealant only needs to be removed, without damaging the inner container 15.

[0167] Preferably, in combination with Figure 7 , Figure 8 and Figure 11As shown, the partition 16 comprises a water guide slope 1681 located on the side of the folded portion 167 away from the inner wall of the cavity, and the water guide slope 1681 extends downwardly in a direction away from the inner wall of the cavity and toward the lower washing cavity 1532.

[0168] Under the action of the water guide slope 1681, during the operation of the dishwasher 1, the impurities such as food residues, oil stains, and dirty water generated in the upper washing cavity 1531 can flow and collect smoothly and quickly toward the inner side of the partition 16, which facilitates centralized discharge, shortens the drainage time, improves the overall working efficiency of the dishwasher 1, reduces the erosion of the impurities to the inner container 15 and other components (such as the spraying device 102), prolongs the service life of the dishwasher 1, avoids the accumulation of impurities in the upper washing cavity 1531, thereby reducing the secondary pollution of the sewage to the tableware and improving the washing effect.

[0169] As a preferred mode of the present embodiment, please refer to Figure 18 and Figure 19 As shown, the partition 16 further comprises a connecting portion 1683 connected between the water guide slope 1681 and the folded portion 167, and the connection is preferably that the connecting portion 1683, the water guide slope 1681, and the folded portion 167 are integrally formed, wherein the connecting portion 1683 is preferably arranged perpendicular to the inner wall of the washing cavity 153, that is, the connecting portion 1683 is arranged parallel to the horizontal plane, and the folded portion 167 extends perpendicular to the connecting portion 1683 to ensure that the folded portion 167 better abuts and fits the inner wall of the cavity. Further, the inner container 15 is protrusively formed with a limiting protruding rib 154 inside the washing cavity 153, and the inner container side wall and the inner container back wall are preferably both provided with the limiting protruding rib 154, and the connecting portion 1683 abuts the limiting protruding rib 154. The cross-sectional shape of the limiting protruding rib 154 can be rectangular, trapezoidal, semicircular, etc., and the cross-sectional shape and size of the limiting protruding rib 154 are not limited here.

[0170] Thus arranged, the following technical effects will be achieved:

[0171] Firstly, the limiting protruding rib 154 is equivalent to adding a reinforcing rib to the surface of the inner container 15, which can improve the rigidity of the inner container 15. The increase in rigidity makes the inner container 15 not easy to bend or deform when subjected to external force, thereby maintaining its original shape and dimensional accuracy. At the same time, the limiting protruding rib 154 also has a damping effect, which can absorb and consume the vibration energy generated during the operation of the dishwasher 1, which is beneficial to improve the anti-vibration performance of the inner container 15, prolong the service life of the inner container 15, and reduce the noise caused by vibration.

[0172] Secondly, during assembly, the worker only needs to align the connecting portion 1683 with the limiting protrusions 154 and abut the connecting portion 1683 of the partition 16 against the bottom of the limiting protrusions 154 to realize the installation and positioning of the partition 16, which greatly improves the positioning efficiency and assembly efficiency, reduces the assembly time and labor cost. At the same time, it can also improve the assembly accuracy of the partition 16, thereby ensuring the relative position accuracy and dimensional accuracy of the upper and lower washing cavities 1531 and 1532.

[0173] Thirdly, when using adhesive connection, the sealing glue can be attached and filled between the limiting protrusions 154 and the connecting portion 1683, thereby increasing the contact area of the adhesive connection between the connecting portion 1683 and the inner wall of the washing cavity 153, thereby improving the strength and stability of the adhesive connection. At the same time, the limiting protrusions 154 can support and fix the connecting portion 1683 to some extent, preventing the connecting portion 1683 from shifting during the curing process of the glue, and ensuring the quality of the adhesive connection. At the same time, the close fit of the limiting protrusions 154 and the connecting portion 1683 can ensure that the relative position of the two does not change during welding, which makes the welding points more accurate and uniform, improving the quality and strength of the welding. During welding, the limiting protrusions 154 can also play a certain role in heat dissipation, which helps to control the temperature of the welding area and reduce the generation of welding deformation and cracks. In addition, stable cooperation can also make the welding process more smooth, improve the welding efficiency and reduce the welding cost. Whether it is adhesive connection or welding connection, the cooperation of the limiting protrusions 154 and the connecting portion 1683 helps to improve the sealing between the partition 16 and the inner wall, effectively preventing water from leaking.

[0174] It should be pointed out that, for details, please refer to Figure 18The angle between the water guide slope 1681 and the connecting portion 1683 is α, and α is not less than 5° and not more than 75°. In this way, the water guide slope 1681 can provide a suitable drainage angle for the sewage in the upper washing cavity 1531. The impurities can stably flow downward under the action of gravity, not only ensuring that the sewage containing residues can be smoothly discharged, reducing the residence time of impurities in the upper washing cavity 1531, improving the drainage efficiency, and reducing the possibility of secondary pollution of the sewage to the tableware. When α < 5°, α is too small, so that the water guide slope 1681 is too flat. When the impurities flow on the water guide slope 1681, the component of gravity along the direction of the water guide slope 1681 is small, and the driving force of the water flow is insufficient, which leads to a significant reduction in the discharge speed. This can make the impurities stay in the upper washing cavity 1531 for too long, and even cause residues in the impurities to easily accumulate on the water guide slope 1681, thereby increasing the risk of secondary pollution of the sewage to the tableware and reducing the washing effect of the dishwasher 1. When α > 75°, α is too large, so that the water guide slope 1681 is too steep. The sewage will flow down at a relatively fast speed under the action of gravity, which not only easily causes splashing. The splashing sewage can splash to other parts of the upper washing cavity 1531, thereby polluting the inside of the dishwasher 1. At the same time, when the high-speed flowing water flow collides with the inner wall of the water guide slope 1681 and the lower washing cavity 1532, a relatively large noise will be generated. This not only affects the user's experience when using the dishwasher 1, but also may, to some extent, reflect the unstable state of the water flow, which adversely affects the overall performance of the dishwasher 1.

[0175] It should also be noted that the specific content is described in detail in Figure 18 The distance between the side of the water guide slope 1681 connected by the connecting portion 1683 and the side of the folded portion 167 is the platform width Bp, and the platform width Bp is not less than 3 mm and not more than 15 mm. If the platform width Bp < 3 mm, the connecting portion 1683 is too narrow, and the space available for forming a weld is small, and a weld with sufficient size and strength cannot be formed. The weld is too narrow and shallow, which can cause insufficient bonding force between the connecting portion 1683 and other components, and greatly limit the space for welding operation, making it difficult for the welding tool to accurately position the part to be welded. The welding gun or welding rod may not be able to stably aim at the connection between the connecting portion 1683, the water guide slope 1681 and the folded portion 167, which can easily cause welding position deviation, thereby easily leading to the problem of substandard welding quality. At the same time, it also greatly increases the difficulty of forming the connecting portion 1683.

[0176] If the platform width Bp is greater than 15 mm, the connecting portion 1683 is too wide, which makes the water flow area too large when the water flows from the connecting portion 1683 to the water guide slope 1681, the flow velocity is dispersed, the kinetic energy of the water flow is weakened, and at the same time, the flow path of the water flow on the connecting portion 1683 is lengthened, which increases the travel time of the water flow and reduces the timeliness of drainage, which is not conducive to the rapid flow of sewage carrying residues to the water guide slope 1681, and may cause part of the sewage and residues to be retained on the connecting portion 1683, affecting the drainage effect.

[0177] The platform width Bp is not less than 3 mm and not greater than 15 mm, which not only helps to ensure the structural strength and stability of the connecting portion 1683 to better withstand the water flow impact and vibration and other external forces during the operation of the dishwasher 1, reduce the risk of loosening, breaking and deformation, and facilitate the welding connection between the connecting portion 1683 and other components. At the same time, it can also ensure smooth water flow and prevent the risk of water flow congestion when flowing from the connecting portion 1683 to the water guide slope 1681, improve the drainage efficiency, thereby helping to keep the platform surface dry, reduce the possibility of bacterial growth, and maintain the cleanliness of the inside of the dishwasher 1.

[0178] In addition, referring to Figure 18 The protrusion height Hb of the limiting protrusion 154 is not less than 1 mm and not greater than 15 mm, which not only provides a clear limiting effect for the partition 16 and ensures the strength of the limiting protrusion 154, so that the limiting protrusion 154 can maintain its structural integrity when subjected to external forces and is not prone to breaking or deforming. If the protrusion height Hb is greater than 15 mm, the limiting protrusion 154 is too high, which may cause stress concentration problems, reduce the overall strength of the main structure, and occupy a lot of vertical space in the upper washing cavity 1531, interfering or hindering the placement of tableware into the upper washing cavity 1531, affecting the washing experience and washing effect. If the protrusion height Hb is less than 1 mm, the limiting protrusion 154 is too small, which is not conducive to the molding of the limiting protrusion 154 by the process.

[0179] As can be understood, referring to Figure 11 The partition 16 further includes a layer bearing portion 1682, and the layer bearing portion 1682 is connected to the water guide slope 1681. The connection is preferably integrally formed to better prevent leakage at the connection between the layer bearing portion 1682 and the water guide slope 1681, and to enhance the stability of the partition 16 as a whole, and the layer bearing portion 1682 and the water guide slope 1681 surround the above-mentioned drainage groove 164.

[0180] It should be noted that, referring to Figure 18As shown, the groove depth dimension Hd of the drain groove 164 is not less than 3 mm and not greater than 20 mm. This can ensure that the drain groove 164 has sufficient space to accommodate water flow, so that the water flow can form a certain depth in the groove and flow stably and orderly in a relatively stable space, avoiding the problem of water flow overflowing the drain groove 164 and being easily disturbed by external factors (air resistance, etc.) due to the groove depth dimension Hd being too shallow (groove depth dimension Hd < 3 mm), affecting the smoothness of drainage. At the same time, it also helps the water flow to flow smoothly under the action of gravity and carries away smaller residues and dirt, reducing the risk of clogging of the drain groove 164. If the groove depth dimension Hd is too shallow (groove depth dimension Hd < 3 mm), the scouring force of the water flow is insufficient, and residues and dirt are easily accumulated at the bottom of the drain groove 164, causing poor drainage or even clogging, effectively reducing the residence time of the water flow in the drain groove 164 and improving the drainage efficiency.

[0181] In addition, the groove depth dimension Hd of the drain groove 164 is not less than 3 mm and not greater than 20 mm, which is also beneficial for processing and forming, and ensures that the overall structure of the drain groove 164 has sufficient structural strength and stability. Because the groove depth dimension Hd of the drain groove 164 affects its overall structural strength. If the groove depth dimension Hd is too large (groove depth dimension Hd > 20 mm), not only is it not conducive to forming, but also makes the structure of other components (such as the water cup 17) at the drain groove 164 too weak, and is prone to deformation, cracking, etc. when subjected to external force or water pressure.

[0182] In addition to the above-mentioned way of providing the folding portion 167 on the partition piece 16 and sealingly connecting the folding portion 167 to the cavity wall of the washing inner cavity 153, the inventors also provide another preferred embodiment, which will be described in detail in combination with Figures 20 to 24 As shown, the above-mentioned partition piece 16 includes a partition plate 160 and a mounting bracket 169, specifically, the inner cavity wall and the back wall of the inner cavity are sealingly connected 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 cavity wall of the washing inner cavity 153 by the mounting bracket 169, so as to divide the washing inner cavity 153 into an upper washing cavity 1531 and a lower washing cavity 1532 arranged in sequence from top to bottom. The upper washing cavity 1531 and the lower washing cavity 1532 are relatively independent.

[0183] In this way, the partition plate 160 and the mounting bracket 169 can be produced as independent workpieces in the factory, and the precision is easier to control. During installation, only the partition plate 160 and the mounting bracket 169 need to be assembled, and then the mounting bracket 169 is accurately installed on the inner cavity wall of the washing inner cavity 153. This not only ensures the accuracy and stability of the partition of the washing cavity, improves the washing effect, but also simplifies the structure of the partition plate 160 and facilitates the assembly, thereby effectively improving the flexibility and applicability of the dishwasher 1, and reducing the production cost of the dishwasher 1.

[0184] Further, in order to ensure the sealing between the partition 16 and the inner container 15, as shown in Figures 20 to 24 , the edge part of the mounting bracket 169 and the inner cavity wall of the washing inner cavity 153 are configured as a partition sealing groove 181, and the partition sealing groove 181 extends along the circumferential direction of the mounting bracket 169. The dishwasher 1 further comprises a partition sealing member 193 embedded in the partition sealing groove 181. The partition sealing member 193 can be made of rubber or silicone. In this way, the sealing problem between the partition 16 and the inner container 15 is effectively solved, and the problem of water leakage between the upper washing cavity 1531 and the lower washing cavity 1532 is prevented, thereby improving the washing effect. In addition, the mounting bracket 169 and the inner container 15 cooperate to form the partition sealing groove 181, which has a simple structure, and the assembly of the partition sealing member 193, the partition 16 and the inner container 15 is more compact, effectively utilizing the limited space of the washing inner cavity 153, and facilitating the reasonable layout of other components in the limited washing inner cavity 153, thereby improving the overall performance of the dishwasher 1.

[0185] Preferably, as shown in Figure 24 , the mounting bracket 169 comprises a fixed part 1691, a spacing part 1692 and a supporting part 1693. The fixed part 1691 is arranged spaced apart from the inner cavity wall of the washing inner cavity 153, and extends towards the upper washing cavity 1531 side and parallel to the inner cavity wall. The spacing part 1692 extends towards the lower washing cavity 1532 side and parallel to the inner cavity wall, so that the contact area between the spacing part 1692 and the inner cavity wall is larger. The spacing part 1692 can be closely fitted on the inner cavity wall, and the spacing part 1692 is fixedly connected to the inner container 15. Here, the fixed connection can be understood as the spacing part 1692 being welded and / or glued to the inner cavity wall, and can also be bolted to the inner cavity wall. Further, the fixed part 1691 and the spacing part 1692 are fixedly connected to the supporting part 1693. Here, the fixed connection is preferably integrally formed, and the fixed part 1691, the supporting part 1693 and the inner cavity wall of the washing inner cavity 153 cooperate to form the partition sealing groove 181.

[0186] Thus, the connection between the mounting bracket 169 and the wall of the washing inner cavity 153 can be made more stable by the fixing portion 1691, which provides a solid support foundation for the entire partition 16, effectively resists external forces from the lower washing cavity 1532, such as water flow impact, gravity of washing items, etc., prevents the partition plate 160 from shaking, shifting or deforming, and ensures that the upper washing cavity 1531 and the lower washing cavity 1532 always maintain a stable partitioning state. At the same time, since the spacing portion 1692 closely fits the inner wall of the cavity, it can fill the gaps that may exist and work together with the partitioning sealing groove 181 formed by the fixing portion 1691, the support portion 1693, and the partitioning sealing member 193 to provide multiple sealing protection, reduce the risk of water leakage, maintain the independence of each washing cavity, and improve the washing effect.

[0187] Further, please refer to Figure 24 , the end of the spacing portion 1692 away from the support portion 1693 is bent to form a folded edge 1694, and the folded edge 1694 and the spacing portion 1692 form an assembly groove 1695, which is a U-shaped groove structure. The above-mentioned partition plate 160 comprises a carrier body 1601 and a sliding plug body 1602, wherein the carrier body 1601 and the fixing portion 1691 are configured as the above-mentioned drainage groove 164, the sliding plug body 1602 is inserted into the assembly groove 1695, and the carrier body 1601 is fixedly connected to the sliding plug body 1602. Here, the fixed connection preferably adopts a bending one-piece molding process, which ensures the strength and stability of the overall structure of the partition plate 160, and is beneficial to enhancing the impact resistance of the partition plate 160 during the washing process. It can be understood that the water cup 17 is installed and fixed on the carrier body 1601.

[0188] Thus, the following unexpected technical effects can be achieved:

[0189] Firstly, the sliding plug body 1602 of the partition plate 160 is inserted into the assembly groove 1695 formed by the folded edge 1694 of the spacing portion 1692, making the installation of the partition plate 160 simple and direct, without the need for complex tools or additional connecting members, simplifying the assembly process, greatly improving the assembly efficiency, and reducing the assembly difficulty. If the partition plate 160 needs to be repaired, replaced, or disassembled and cleaned, the sliding plug body 1602 can be easily pulled out of the assembly groove 1695, and the corresponding operation can be easily performed, realizing the assembly convenience and flexibility of the partition plate 160.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] It should also be noted that, for details please refer to [link / reference]. Figure 24The distance between the end of the fixing portion 1691 away from the supporting portion 1693 and the supporting portion 1693 in the direction perpendicular to the supporting portion 1693 and towards the side of the washing cavity 1531 is the length dimension L1 of the fixing portion 1691, and the length dimension L1 is not less than 5 mm and not greater than 25 mm. In this way, the structural strength of the fixing portion 1691 can be better ensured, and the fixing portion 1691, the supporting portion 1693 and the wall of the washing inner cavity 153 can be combined to form a stable separation sealing groove 181, so that the separation sealing member 193 can be better embedded and have good sealing effect.

[0194] If the length dimension L1 is less than 5 mm, the fixing portion 1691 is too short and has insufficient strength, and cannot form an effective separation sealing groove 181 with the supporting portion 1693 and the wall of the washing inner cavity 153, the sealing performance is reduced, water leakage phenomenon is easy to occur, and the washing effect is reduced. Moreover, it is not conducive to bending the fixing portion 1691, and the production difficulty of bending is increased. If the length dimension L1 is greater than 25 mm, the fixing portion 1691 is too long, the structure becomes complex, the material cost and weight are increased. At the same time, too much space of the washing inner cavity 153 is occupied, the installation and layout of other components are affected, the reasonable placement of washing articles is not conducive, and the utilization rate of the washing space may be reduced. Moreover, the fixing portion 1691 is more prone to bending deformation under stress, and the structural stability is further affected.

[0195] Preferably, as shown in Figure 23 and Figure 24 , the inner container 15 is protruded towards the inside of the washing inner cavity 153 and is formed with the above-mentioned limiting protruding ribs 154, at this time, the limiting protruding ribs 154 are located above the separation sealing groove 181, and when the separation sealing member 193 is assembled and embedded into the separation sealing groove 181, the separation sealing member 193 partially protrudes out of the separation sealing groove 181 and abuts against the limiting protruding ribs 154. In this way, when the separation sealing member 193 partially protrudes out of the separation sealing groove 181 and abuts against the limiting protruding ribs 154, an additional sealing line is formed. During the washing process, even if a small amount of water penetrates near the separation sealing groove 181, it will be blocked by the limiting protruding ribs 154 and the protruding part of the separation sealing member 193, and cannot continue to leak between the upper washing cavity 1531 and the lower washing cavity 1532, further enhancing the sealing performance of the dishwasher 1, effectively avoiding water leakage phenomenon, and ensuring the washing effect. At the same time, the limiting protruding ribs 154 can be used as a positioning mark during assembly. When the separation sealing member 193 is assembled and embedded into the separation sealing groove 181, when the separation sealing member 193 abuts against the limiting protruding ribs 154, it can be determined that the separation sealing member 193 has been installed in place, which is convenient for operation and improves the assembly efficiency.

[0196] It should be noted that, for details, please refer to Figure 24The above-mentioned partition seal 193 comprises a seal body 1931, and a rubber strip height he of the seal body 1931 is greater than a length dimension L1, and the rubber strip height he is not less than 6 mm and not greater than 30 mm, and the rubber strip height he is a length dimension of the seal body 1931 in a direction perpendicular to the support portion 1693. In this way, the partition seal 193 can be ensured to protrude into the partition seal groove 181 and form a closer abutment with the limiting protruding rib 154, effectively blocking water leakage, and at the same time, better adapt to various situations during operation of the dishwasher 1. When the dishwasher 1 vibrates or is impacted by external force, the partition seal 193 can be buffered by elastic deformation of the partition seal 193 itself to maintain the sealing effect and ensure the stability of the partition seal 193, thereby ensuring normal operation of the dishwasher 1.

[0197] If the rubber strip height he < 6 mm, the seal body 1931 is too short, and it is difficult to form an effective abutment with the limiting protruding rib 154, the sealing effect is greatly reduced, and water leakage is likely to occur during the washing process, affecting the normal use of the equipment, and may also cause damage to other parts inside the equipment. Moreover, the shorter seal body 1931 lacks sufficient buffering capacity when subjected to external force, and cannot effectively maintain the stability of the partition structure. If the rubber strip height he > 30 mm, the seal body 1931 is too high, which will cause material waste and increase the cost. The excessively high seal body 1931 is prone to excessive deformation when subjected to extrusion, and may even bend, break, or the like, resulting in sealing failure.

[0198] It should be noted that the specific content is described in detail in the Figure 24 The above-mentioned partition seal 193 further comprises a rubber strip drainage portion 1932, which is inclinedly extended from an end portion of the seal body 1931 to the limiting protruding rib 154. Specifically, the rubber strip drainage portion 1932 is located at the end portion of the seal body 1931 protruding into the partition seal groove 181, and the rubber strip drainage portion 1932 is inclinedly extended from a side close to the fixed portion 1691 to the bottom of the limiting protruding rib 154, and the rubber strip drainage portion 1932 is fixedly connected with the seal body 1931, and the fixed connection here is preferably an integral molding process.

[0199] On the one hand, the rubber strip drainage portion 1932 is tightly fitted with the limiting protruding rib 154, so as to realize the purpose of abutting the partition seal 193 with the limiting protruding rib 154 to form a sealing line. On the other hand, the rubber strip drainage portion 1932 can also guide the water flow along the inclined surface thereof to the drainage groove 164, so as to avoid water accumulation near the partition seal 193, and further enhance the waterproof effect, thereby being beneficial to improving the washing effect.

[0200] It should be noted that the specific content is described in detail in the Figure 24The angle between the rubber strip drainage portion 1932 and the horizontal plane is ε, and ε is not less than 5° and not greater than 75°. In this way, the rubber strip drainage portion 1932 can have sufficient inclination to guide the water flow and smoothly drain the residue, while ensuring that the rubber strip drainage portion 1932 is not too steep to prevent the water flow from impacting the internal structure of the dishwasher 1, and facilitating manufacturing and installation to ensure the fitting accuracy between the rubber strip drainage portion 1932 and the limiting protrusion 154. If ε < 5°, the slope of the rubber strip drainage portion 1932 is insufficient, the water flow cannot be smoothly drained, and the rubber strip drainage portion 1932 is prone to accumulate water, resulting in a decrease in sealing performance. If ε > 75°, the slope of the rubber strip drainage portion 1932 is too large, resulting in a too fast water flow, which can impact the internal structure of the dishwasher 1 and increase the difficulty of manufacturing and installation.

[0201] It should also be noted that specific reference can be made to Figure 24 The distance between the fixed portion 1691 and the cavity inner wall of the washing cavity 153 is the groove width Bt of the separation sealing groove 181, and the groove width Bt is not less than 3 mm and not greater than 20 mm. In this way, not only is it convenient to bend and form the structure of the three portions of the fixed portion 1691, the supporting portion 1693 and the spacing portion 1692, but also sufficient space can be ensured for the installation of the separation sealing member 193, ensuring the integrity and normal operation of the separation sealing member 193, avoiding the problems of difficult installation or deformation of the separation sealing member 193 due to too narrow space or looseness due to too wide space, affecting the sealing effect. When the groove width Bt < 3 mm, the separation sealing groove 181 is too narrow, and the separation sealing member 193 is difficult to install in place, even if it is forced to install, it is easy to be deformed due to extrusion, and cannot play a normal sealing role, greatly increasing the risk of water leakage. At the same time, it also increases the process difficulty of forming the supporting portion 1693. When the groove width Bt > 20 mm, the separation sealing groove 181 is too wide, and the separation sealing member 193 cannot tightly fill the groove, and the separation sealing member 193 is prone to shift in the separation sealing groove 181 during the operation of the dishwasher 1, resulting in failure of the separation sealing member 193.

[0202] Further, along the direction of the groove width, the rubber strip width be of the sealing member body 1931 is greater than the groove width Bt, and the wider sealing member body 1931 can better fill the separation sealing groove 181, so that the separation sealing member 193 and the separation sealing groove 181 form an interference fit. During the washing process, even if affected by external forces such as water flow impact and dishwasher 1 vibration, the separation sealing member 193 can always be tightly attached to the groove wall of the separation sealing groove 181, effectively blocking water leakage, ensuring the sealing between the upper washing chamber 1531 and the lower washing chamber 1532, and protecting the washing effect. At the same time, in the actual production process, there may be certain manufacturing errors in each part of the dishwasher 1, and the groove width Bt of the separation sealing groove 181 is also difficult to be completely consistent. The rubber strip width be is greater than the groove width Bt, which can effectively compensate for these errors. Even if the groove width is slightly larger than the standard size, the wider rubber strip can still achieve good sealing, improving the universality and stability of the product.

[0203] It should be added that the rubber strip width be is not less than 4 mm and not greater than 25 mm. In this way, the separation sealing member 193 can effectively fill the separation sealing groove 181, and excessive extrusion deformation of the separation sealing member 193 can be avoided, the sealing effect can be ensured, and water flow leakage can be blocked. At the same time, excessive waste of separation sealing member 193 material is also avoided. When the rubber strip width be < 4 mm, the sealing member body 1931 is too narrow, and when facing the narrowest 3 mm groove width Bt, it may not be able to completely fill the separation sealing groove 181, the sealing effect is greatly reduced, and water leakage is likely to occur during the washing process, affecting the normal use of the dishwasher 1 and reducing the performance of the dishwasher 1. When the rubber strip width be > 25 mm, the sealing member body 1931 is too wide, and it may be difficult to smoothly put into the widest 20 mm separation sealing groove 181 during installation. Forced installation will cause excessive extrusion deformation of the separation sealing member 193, affecting the sealing performance. Moreover, the excessively wide separation sealing member 193 will increase the material cost, and may also damage the fixing part 1691 and the inner cavity wall of the washing inner cavity 153 due to uneven stress, reducing the stability and service life of the dishwasher 1.

[0204] In addition, please refer to Figure 24 , the separation sealing member 193 further comprises a rubber strip extension 1933, which is arranged extending from and inclined to the center line of the sealing member body 1931, and the rubber strip extension 1933 is preferably arranged upwardly inclined, wherein the rubber strip extension 1933 is preferably configured as a plurality, and the plurality of rubber strip extensions 1933 are evenly arranged and distributed on the sealing member body 1931 along the center line of the sealing member body 1931. The rubber strip extension 1933 abuts the inner groove wall of the separation sealing groove 181, and the rubber strip extension 1933 is fixedly connected with the sealing member body 1931, and the fixed connection here is preferably integrally formed.

[0205] In this way, the upwardly inclined extension 1933 of the rubber strip can naturally guide the installation of the partition seal 193. When the partition seal 193 is placed in the partition seal groove 181, the extension 1933 of the rubber strip first contacts the groove wall of the partition seal groove 181, and the inclined shape guides the partition seal 193 to slide into the groove accurately. At the same time, the extension 1933 of the rubber strip has a certain elasticity, and can be self-adapted and adjusted by deformation during installation, even if there is a slight deviation in the size of the partition seal groove 181. When the extension 1933 of the rubber strip is pressed by the groove wall of the partition seal groove 181, it can be slightly bent or contracted, so that the partition seal 193 can be installed in place smoothly, and the difficulty and time of alignment during installation are greatly reduced, and the installation efficiency is improved.

[0206] It should be noted that the included angle between the extension 1933 of the rubber strip and the center line of the main body 1931 of the seal is θ, and θ is not less than 90° and not greater than 150°. In this way, the extension 1933 of the rubber strip can be effectively ensured to be in a relatively relaxed state during installation of the partition seal 193, fully play its guiding and self-adapted adjusting role, and form good contact with the inner groove wall of the partition seal groove 181, effectively guide the partition seal 193 to be installed in place, and maintain stable sealing performance during operation of the dishwasher 1. When θ < 90°, the extension 1933 of the rubber strip 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 extension 1933 of the rubber strip is too inclined, and is likely to be excessively bent in the groove during installation, or even broken, affecting installation and use, and the extension 1933 of the rubber strip may also be unevenly stressed, reducing the stability and service life of the partition seal 193.
