[0029] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0030] The following description of the drawings relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following example embodiments do not represent all the embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" means two or more. "And / or", the association between the associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A, the existence of A and B, and the existence of B. The character " / " generally represents the "or" relationship between the associated objects before and after.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled 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 related listed items.

[0033] With the continuous progress of society, people have higher and higher requirements for the intelligence of kitchen appliances. Dishwashers are favored by people because they can reduce the labor burden of people in modern life due to their good cleaning effect, multiple disinfection functions, and time and labor saving.

[0034] The present application provides a dishwasher that can effectively remove food residues on the surface of tableware (bowls, plates, etc.), disinfect and sterilize tableware during the cleaning process, and dry tableware after cleaning and disinfection. Among them, disinfection and sterilization can add cleaning liquid to the water used to clean tableware, and control the internal environment of the dishwasher (including the water temperature of the cleaning liquid) 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 tableware. The drying method of the dishwasher can be heat exchange drying, hot air drying, etc., which can effectively prevent bacteria from growing and odors from being produced due to moisture on the tableware.

[0035] In related technologies, the dishwasher is only configured with one washing cavity, and the space of the washing cavity is fixed. Therefore, it is not flexible to adjust according to the actual number of tableware of the user. For example, when the user needs to clean a small amount of tableware, part of the space cannot be utilized, and the water in the cleaning process will still be sprayed in the blank area where no tableware is placed, which not only causes space waste, but also cannot fully exert the efficiency of the dishwasher.

[0036] In addition, when the washing cavity is divided into two, three or more sub-cavities to meet the user's washing requirements in multiple scenes, each sub-cavity needs to be equipped with a separate water system to better control the water of each sub-cavity. At this time, multiple water systems are carried on the dishwasher, which will cause the dishwasher to occupy a large space and have a bulky structure, and cannot meet the different use requirements of the user.

[0037] To solve the above problems, please refer to Figures 1 to 3 The dishwasher 1 provided in the present application includes a shell, an inner container 10, a partition 20, and an upper cavity water system 30.

[0038] The inner container 10 is arranged in the outer shell and has a washing inner cavity, so that tableware can be stored in the washing inner cavity and cleaned, sterilized and dried. The partition 20 is assembled in the washing inner cavity to divide the washing inner cavity into an upper washing cavity 110 and a lower washing cavity 121. On the one hand, by arranging the relatively independent upper washing cavity 110 and the lower washing cavity 121, the cleaning demand of different amounts of tableware can be better met. When the user has a large amount of tableware to be cleaned, the upper washing cavity 110 and the lower washing cavity 121 can be used at the same time, the total washing space is increased, the space utilization is improved, and the user's diversified use demand is met.

[0039] It should be noted that the space size of the upper washing cavity 110 can be different from that of the lower washing cavity 121. For example, the space size of the upper washing cavity 110 is smaller than that of the lower washing cavity 121, so that the type of tableware placed in the upper washing cavity 110 is different from that of the lower washing cavity 121, so that the tableware can be placed more compactly. Alternatively, the space size of the upper washing cavity 110 can also be the same as that of the lower washing cavity 121. When the amount of tableware is small, the user can only use one of the washing cavities. Therefore, the space waste of a single large-capacity washing cavity when cleaning a small amount of tableware is avoided. In this way, the space utilization of the dishwasher 1 is more reasonable, meets the user's use demand in different tableware quantity scenarios, and fully utilizes the performance of the dishwasher 1.

[0040] On the other hand, the independent upper washing cavity 110 and the lower washing cavity 121 make the cleaning process more clear. 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 tableware cleaning demand.

[0041] In the embodiment, the inner container 10 comprises an upper shell assembly 11 and a lower shell assembly 12. The upper shell assembly 11 can have an upper top wall, an upper back wall, and upper side walls, the number of which is configured to be two, and the two upper side walls are oppositely arranged and are both connected perpendicularly to the upper top wall to form a U-shaped workpiece, and the upper top wall can be integrally formed with the two upper side walls, and the upper back wall can be integrally formed with the upper top wall and fixedly connected with the upper side walls. In this way, the connection points between the workpieces can be reduced, the continuity is better, the overall structural strength of the upper shell assembly 11 is higher, and the inner container 10 can better withstand the internal water pressure and external forces such as possible collisions during long-term use of the dishwasher 1, thereby reducing the risk of damage such as cracking and deformation, and also helping to ensure the sealing of the upper shell assembly 11 and effectively prevent the risk of water leakage from the spliced joint, thereby improving the reliability and service life of the inner container 10 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 simplify the production process, improve production efficiency and processing accuracy, and reduce the cost of manpower and material resources during production. In addition, the surface of the integrally formed upper shell assembly 11 is smoother, reducing the splicing gap, and food residues are less likely to accumulate in the gap during cleaning of the inner container 10, not only reducing the cleaning difficulty, but also preventing the risk of bacterial and mold breeding in the gap, thereby ensuring the dishwasher 1 and ensuring that the cleaned tableware is more hygienic.

[0042] In addition to the above-mentioned manner, the upper back wall can be integrally formed with one of the upper side walls and fixedly connected with the upper top wall, which can also ensure the overall structural strength and stability of the upper shell assembly 11 and has production process and cost advantages. It should be noted here that the upper top wall is fixedly connected with the two upper side walls. The fixed connection here should be understood as that the upper back wall, the upper top wall, and the two upper side walls are all separately formed workpieces, which is conducive to fine processing and quality control of each separate workpiece, and also makes the production process and assembly process more flexible. In the assembly process, the upper back wall, the upper top wall, and the two upper side walls are first engaged and spliced adjacent to each other and then welded or riveted, and are subjected to glue sealing treatment. In actual production process, considering factors such as production difficulty, production demand, and production cost, the splicing assembly and integral molding are combined for production and manufacturing.

[0043] Correspondingly, the lower shell assembly 12 can also include a lower bottom wall, a lower top wall, two lower side walls and a lower back wall. The two lower side walls are oppositely arranged and vertically connected to the lower top wall. The lower top wall is oppositely arranged with the lower bottom wall. The lower top wall is integrally formed with the two lower side walls, and the two upper side walls are connected to the lower bottom wall to form a mouth-shaped workpiece. The lower back wall is integrally formed with the upper top wall and is fixedly connected to the lower bottom wall and the two lower side walls. Alternatively, the lower back wall can be integrally formed with one of the two lower side walls and is fixedly connected to the lower top wall and the lower bottom wall. The overall structural strength and stability of the lower shell assembly 12 can be ensured. In the assembly process, the lower back wall, the lower top wall, the lower bottom wall and the two lower side walls are first engaged and then welded, riveted or sealed by glue. The present application does not limit this.

[0044] In summary, the U-shaped upper shell assembly 11 is stacked and mounted on the top of the mouth-shaped lower shell assembly 12. The upper shell assembly 11 and the lower shell assembly 12 can be independently machined during production. Subsequently, only the upper shell assembly 11 and the lower shell assembly 12 need to be assembled to form the upper washing cavity 110 and the lower washing cavity 121 to meet the different use requirements of users. This stacking and mounting 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 split-cavity dishwasher 1, which leads to complicated assembly. The simple overall structure also helps to reduce the cost of production.

[0045] It should be noted that when the dishwasher 1 is provided with a door body facing the user's standing direction, the front-to-back direction of the dishwasher 1 inner container 10 described in the present application is the user's facing direction, and the left and right sides of the dishwasher 1 inner container 10 are the user's left and right sides. One of the two upper side walls defined above is defined as an upper left side wall, and the other is an upper right side wall. One of the two lower side walls defined above is defined as a lower left side wall, and the other is a lower right side wall. The upper left side wall is coplanar with the lower left side wall, and the upper right side wall is coplanar with the lower right side wall. 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.

[0046] In this way, the upper shell assembly 11 and the lower shell assembly 12 can better support each other at the connection part, enhancing the stability and firmness of the entire dishwasher 1 inner container 10 structure and reducing the possibility of deformation or damage caused by vibration during washing. At the same time, during assembly, it is beneficial to the alignment and connection of the upper shell assembly 11 and the lower shell assembly 12, reducing the difficulty and precision requirements of assembly and improving the assembly efficiency. It also makes the side lines of the dishwasher 1 more smooth and neat, improving the overall aesthetics and meeting the aesthetic needs of users for product appearance design.

[0047] In addition to the separation of the washing inner cavity into the upper washing cavity 110 and the lower washing cavity 121 by the upper top wall of the upper shell assembly 11 or the lower top wall of the lower shell assembly 12, in an embodiment of the present application, the partition 20 is inserted into the upper shell assembly 11 and cooperates with the upper shell assembly 11 to define the upper washing cavity 110, and the partition 20 is inserted into the lower shell assembly 12 and cooperates with the lower shell assembly 12 to define the lower washing cavity 121. At this time, the upper surface of the partition 20 forms the wall surface of the upper bottom wall of the upper shell assembly 11, and the lower surface of the partition 20 forms the lower top wall of the lower shell assembly 12. The upper shell assembly 11 and the lower shell assembly 12 are respectively inserted into the partition 20 to divide the washing inner cavity into the upper washing cavity 110 and the lower washing cavity 121. This arrangement simplifies the assembly process, reduces the difficulty of assembly and the requirement for worker skills, improves the assembly speed, and reduces the assembly time and labor cost. In the assembly process or the replacement process in the later maintenance, the upper shell assembly 11 or the lower shell assembly 12 can be more conveniently separated from the partition 20, which reduces the disassembly and repair difficulty, thereby reducing the assembly cost and repair cost.

[0048] In an embodiment of the present application, please refer to Figures 1 to 5 The dishwasher 1 further comprises a lower cavity waterway system 40 and a base connected to the bottom of the outer shell and located below the bottom disc 50 of the inner container 10. The lower cavity waterway system 40 is suitable for supplying and draining water to the lower washing cavity 121, and the upper and lower cavity independent waterway systems can realize independent washing of the upper and lower cavities. Users can open only the upper cavity or the lower cavity for washing according to needs during the washing process, which can save water resources and energy, and also can flexibly select according to different numbers and types of tableware. Of course, the two washing cavities can also work in parallel to shorten the overall washing time. Moreover, when one washing cavity fails or needs maintenance, the other washing cavity can still be used normally, which will not affect the daily tableware cleaning needs of users.

[0049] The lower cavity waterway system 40 is located between the base and the bottom disc 50. The space between the base and the bottom disc 50 is usually compact. Placing the lower cavity waterway system 40 in this space can make full use of the space, avoid occupying other areas, effectively utilize the space at the bottom of the dishwasher 1, improve the space utilization rate, and shorten the length of the pipeline for supplying and draining water to the lower cavity, improve the water supply efficiency, and reduce energy loss, realize efficient water supply and drainage, and facilitate maintenance and repair of the lower cavity waterway system 40.

[0050] The upper cavity waterway system 30 is suitable for supplying and draining water to the upper washing cavity 110. The upper cavity waterway system 30 is arranged on one side of the left and right sides of the inner container 10 between the outer shell and the inner container 10, that is, the upper cavity waterway system 30 can be arranged on the left side or the right side of the inner container 10. The technical scheme of the present application arranges the upper cavity waterway system 30 on one side of the left and right sides of the inner container 10, fully utilizes the space between the outer shell and the inner container 10, avoids occupying additional space due to the dispersion of components of the upper cavity waterway system 30, reduces the interference between the pipelines and the components, and improves the stability of the system operation. This design makes the overall structure of the dishwasher 1 more compact, helps to reduce the size of the equipment, meets the size requirements of modern kitchens for household appliances, and meets the diversified washing needs of users. The upper cavity waterway system 30 is arranged on one side of the left and right sides of the inner container 10, which is convenient for separate disassembly and maintenance. If a component fails, it can be quickly located and replaced without the need to disassemble the entire waterway system.

[0051] The upper cavity waterway system 30 is arranged between the portion of the inner container 10 corresponding to the lower washing cavity 121 and the outer shell. Compared with placing the upper cavity waterway system 30 and the lower cavity waterway system 40 together between the base and the bottom disc 50, this arrangement makes the upper cavity waterway system 30 closer to the upper washing cavity 110, shortens the length of the water supply and drainage pipeline, reduces the water flow resistance, and can pump in or drain water faster, shortens the washing and drainage time, improves the water supply and drainage efficiency, and can also quickly drain sewage through gravity, avoid sewage retention, reduce the possibility of secondary pollution, and thus improve the washing efficiency, thereby better meeting the diversified washing needs of users.

[0052] In some embodiments, the inner container 10 includes a body and a receiving portion 14 connected to the body. The body includes an upper shell assembly 11 and a lower shell assembly 12. The receiving portion 14 forms part of the cavity wall surface of the lower washing cavity 121 and extends below the partition 20. The receiving portion 14, the lower wall surface of the partition 20, and the outer shell collectively define a mounting space 101. The upper cavity waterway system 30 includes an upper cavity water cup 35 connected to the partition 20. The upper cavity water cup 35 is arranged in the mounting space 101. The upper cavity waterway system 30 further includes an upper cavity washing pump 31 and an upper cavity drainage pump 32 connected to the upper cavity water cup 35, respectively. The upper cavity washing pump 31 and the upper cavity drainage pump 32 are both located in the mounting space 101, and are arranged along the front-rear direction. This arrangement can isolate the vibrations generated during the operation of the upper cavity washing pump 31 and the upper cavity drainage pump 32, reduce the influence of vibrations on other components, and reduce noise and wear.

[0053] Specifically, the accommodation portion 14 can be recessed downward from the lower side wall of the lower shell assembly 12 to the direction of the lower washing cavity 121. Of course, the accommodation portion 14 can also be a separate workpiece and be fixedly connected to the lower shell assembly 12 by screwing, welding or gluing, etc. The lower side wall of the lower shell assembly 12 has a notch at a position corresponding to the accommodation portion 14, so that the accommodation portion 14, the lower wall surface of the partition 20 and the outer shell jointly define the mounting space 101, and the upper cavity waterway system 30 is accommodated in the mounting space 101.

[0054] The partition 20 is also provided with a slot 21 opening upward. The upper cavity water cup 35 communicates with the upper washing cavity 110 through the slot 21. The slot 21 is used to output the sewage produced by the upper washing cavity 110 to the outside of the upper washing cavity 110. That is, the sewage after washing tableware can be collected in the upper cavity water cup 35 through the slot 21 and discharged. It can be understood that the slot 21 can also be equipped with a filter (such as a filter screen, a filter cover, etc.). On the one hand, food residues, oil, debris and other impurities will fall off the tableware during the washing process. The filter can effectively intercept these impurities to prevent them from clogging the pipeline or entering other parts of the dishwasher 1 when the sewage is discharged. On the other hand, the filter 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 the reattachment of impurities on tableware, and ensure that tableware can be thoroughly washed.

[0055] In some embodiments, the side wall of the upper shell assembly 11 is provided with a first plug-in portion, and the partition 20 is provided with a first plug-in slot in which the first plug-in portion is inserted. The first plug-in slot opens upward to cooperate with the first plug-in portion. The first plug-in slot includes a first inner side wall and a first outer side wall. The first inner side wall is located on the side close to the upper shell assembly 11, and the first outer side wall is located on the side away from the upper shell assembly 11 and is arranged opposite to the first inner side wall.

[0056] Correspondingly, the partition 20 is also provided with a second plug-in slot opening downward, and the lower shell assembly 12 is provided with a second plug-in portion. The first plug-in portion can be arranged on the upper back wall or the upper side wall, and the second plug-in portion can be arranged on the lower back wall or the lower side wall. When assembled, the first plug-in portion is inserted into the first plug-in slot, and the upper shell assembly 11 and the partition 20 are arranged to form the upper washing cavity 110. The second plug-in portion is inserted into the second plug-in slot, and the lower shell assembly 12 and the partition 20 are arranged to form the lower washing cavity 121. Thus, the upper washing cavity 110 and the lower washing cavity 121 are relatively independent, which can better meet the cleaning needs of different amounts of tableware and be suitable for different washing scenarios to meet the different use needs of users.

[0057] The plug-in assembly mode described above also helps to improve the assembly precision. The first slot and the second slot can be used as positioning structures to guide the upper shell assembly 11 and the lower shell assembly 12 to be accurately mounted to the two sides of the partition 20, thereby ensuring the position precision and structural stability of the upper washing cavity 110 and the lower washing cavity 121. Such an accurate assembly mode 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, and the like, thereby improving the quality stability of the product.

[0058] In some embodiments, the height dimension of the first inner side wall is smaller than the height dimension of the first outer side wall, that is, a height difference is formed between the first inner side wall and the first outer side wall. In this way, the higher first outer side wall can form a relatively high blocking structure on the side away from the upper washing cavity 110. When the dishwasher 1 is working, even if a small amount of washing water seeps from the connection between the first plug-in part and the first slot, it will be blocked by the higher first outer side wall and is not easy to flow out of the washing cavity directly, but will form a relatively static water seal area in the first slot, further preventing 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 is relatively small and close to the side of the upper washing cavity 110, so that the water flow is more likely to flow back into the upper washing cavity 110 along the connection between the first plug-in part and the first slot under the action of gravity and the internal pressure of the washing cavity, rather than accumulating at the connection to cause leakage.

[0059] In some embodiments, a flow guide slope is further provided on the partition 20. The flow guide slope is formed on the upper wall surface of the partition 20 and is inclined towards the slot 21, that is, the flow guide slope is inclined to the first inner side wall. Specifically, the flow guide slope is inclined downward along the direction close to the center of the upper shell assembly 11. The flow guide slope here can be a plane, that is, the flow guide slope has a chamfer structure. Of course, the flow guide slope can also be an arc surface provided in a convex manner, that is, the flow guide slope has a rounded corner structure; or the flow guide slope can also be an arc surface provided in a concave manner. In this way, under the action of the flow guide slope, the water flow flows along the inclined direction of the flow guide slope, avoiding irregular splashing or directly vertical downward flow, which helps to more concentratedly guide the water flow to a specific position.

[0060] Meanwhile, during the operation of the dishwasher 1, a large amount of water vapor is generated in the interior, and the inclined flow guide slope can enable the condensed water vapor to be more quickly concentrated and guided to the slot 21 on the partition 20, so as to better converge the water flow, avoid irregular condensation of the water vapor on the first inner side wall to form water droplets, and accelerate the drainage speed. This not only reduces the problem of moisture in the interior of the dishwasher 1 caused by condensation of the water vapor, but also helps to shorten the duration of the moist environment in the interior of the upper washing cavity 110, maintain a dry environment in the interior of the upper washing cavity 110, reduce the problems of corrosion and mildew of components caused by moisture, and reduce the water accumulation time in the upper washing cavity 110, which is beneficial to improving the overall working efficiency of the dishwasher 1, especially enabling the drainage operation to be more quickly completed during the drainage stage, saving time for subsequent rinsing, drying and other processes, and improving the reliability and stability of the dishwasher 1.

[0061] In some embodiments, referring to Figure 1 , and Figure 4 , the upper cavity waterway system 30 further comprises an upper cavity drain pipe 36, which is in communication with the outlet side of the upper cavity drain pump 32 and is used for draining washing water in the upper washing cavity 110 to the outside. The upper cavity drain pipe 36 comprises a first drain section 361, an elbow section 362 and a second drain section 363 which are sequentially communicated. The first drain section 361 is connected with the outlet side of the upper cavity drain pump 32, and the highest position of the center line of the elbow section 362 is higher than the upper surface of the cavity bottom wall of the upper washing cavity 110 formed by the partition 20. This can prevent backflow of water flow during drainage, prevent water from leaking out of the upper cavity drain pipe 36 during washing, and ensure smooth drainage.

[0062] As shown in Figure 5 , there is a height difference H between the highest position of the center line of the elbow section 362 and the upper surface of the partition 20, and the height difference H is greater than or equal to 5 mm. In actual operation, there is inevitably some washing water remaining in the upper washing cavity 110, which cannot be immediately drained out of the upper washing cavity 110 through the upper cavity water cup 35. Therefore, in actual use, there is a height difference H between the highest position of the center line of the elbow section 362 and the actual highest water level in the upper washing cavity 110, and the height difference H is greater than or equal to 5 mm. The height difference H can be 5 mm, 6 mm or 7.5 mm, etc. The present application does not limit this. It can be understood that the height difference H should not be too large, otherwise the height of the elbow section 362 will be too high, which will cause the drainage pressure difference to be too large, increase the difficulty of drainage, and make the structure of the upper cavity drain pipe 36 redundant.

[0063] In some embodiments, the upper washing cavity 110 is provided with an upper cavity spraying device 60, the upper cavity spraying device 60 is arranged on the partition 20 and communicates with the upper cavity waterway system 30, the lower washing cavity 121 is provided with a lower cavity spraying device 70, the lower cavity spraying device 70 is arranged on the bottom disc 50 and communicates with the lower cavity waterway system 40; or, only the upper cavity spraying device 60 or only the lower cavity spraying device 70 can be provided, and the cavity without the spraying device can be used for sterilization and drying alone, so as to realize the simplification of the structure of the dishwasher 1 and ensure the diversity of the functions of the dishwasher 1, thereby meeting the diversified use experience of the user.
