[0009] In some embodiments, the upper surface of the partition member is provided with a drainage opening in communication with the internal waterway, and the drainage opening is arranged at the lowest part of the upper surface of the partition member.

[0010] In some embodiments, the upper surface of the partition member gradually decreases from the side far away from the drainage opening to the side close to the drainage opening.

[0011] In some embodiments, the upper surface of the partition member is further concavely formed with a water passing groove, and the drainage opening is arranged at the groove bottom of the water passing groove.

[0012] In some embodiments, the distance between the drain and the back wall of the upper washing cavity is less than the distance between the drain and the front wall of the upper washing cavity.

[0013] In some embodiments, the thickness of the partition member gradually decreases from front to back along the cabinet.

[0014] In some embodiments, the dishwasher further comprises a filter member embedded in the drain and located in the internal waterway.

[0015] In some embodiments, the waterway system comprises a first drain pipe arranged in the lower washing cavity and attached to the lower surface of the partition member and the cavity wall of the lower washing cavity, the first drain pipe being in communication with the drain through the internal waterway.

[0016] In some embodiments, the dishwasher further comprises a first water inlet pipe and a first spray member, the internal waterway being in communication with the waterway system through the first water inlet pipe.

[0017] The first spray member is connected to the upper surface of the partition member and in communication with the internal waterway to spray and rinse the upper washing cavity.

[0018] In some embodiments, the first spray member comprises a spray cover plate mounted on the upper surface of the partition member, the spray cover plate being provided with a plurality of spray holes in communication with the internal waterway.

[0019] In some embodiments, the first spray member further comprises a spray arm movably connected to the upper surface of the partition member, the spray arm being provided with spray holes in communication with the internal waterway, the spray arm being arranged in a staggered manner with the spray holes.

[0020] In some embodiments, the spray arm is located in the middle of the upper surface of the partition member, and a plurality of the spray holes are located between the spray arm and the boundary of the partition member.

[0021] In some embodiments, a plurality of the spray holes are located on the same side of the spray arm and arranged from front to back along the cabinet.

[0022] In some embodiments, the spray holes comprise first sub-holes and second sub-holes, a plurality of the first sub-holes being located on one side of the spray arm and arranged from front to back along the cabinet, and a plurality of the second sub-holes being located on the opposite side of the spray arm and arranged from front to back along the cabinet.

[0023] In some embodiments, the cavity wall of the cabinet is provided with a groove, and the partition member is embedded in the groove, and the partition member is bonded or screw-connected with the inner wall of the cabinet.

[0024] In some embodiments, the cabinet further comprises a support member connected to the cavity wall of the cabinet, and the partition member is bonded or screw-connected with the support member.

[0025] In some embodiments, the volume of the upper washing cavity and the lower washing cavity is not equal.

[0026] In some embodiments, the front side of the cabinet is provided with a first drop opening communicating with the upper washing cavity and a second drop opening communicating with the lower washing cavity.

[0027] The dishwasher further comprises:

[0028] a first door body movably connected with the cabinet for closing or opening the first drop opening; and

[0029] a second door body movably connected with the cabinet for closing or opening the second drop opening.

[0030] The dishwasher based on the embodiments of the present application realizes effective layering of the inner cavity of the cabinet by arranging the partition member, and forms the upper washing cavity and the lower washing cavity which are independent of each other. This design makes the cleaning of tableware in the upper washing cavity completely isolated from the cleaning in the lower washing cavity, avoiding the mutual influence of the water flow. At the same time, since the volume of the upper washing cavity and the lower washing cavity is not equal, the use of which washing cavity to clean can be flexibly selected according to the actual number of tableware. The smaller upper washing cavity is suitable for cleaning a smaller amount or smaller tableware, while the larger lower washing cavity is more suitable for accommodating a large amount or large tableware. This design not only ensures the cleaning effect, but also significantly saves water resources and energy consumption, because the entire washing system does not need to be started when cleaning a small batch of tableware, thereby reducing unnecessary energy consumption. At the same time, this also shortens the cleaning cycle, further improving the overall cleaning efficiency and energy utilization rate of the dishwasher.

[0031] In addition, the partition member not only plays a blocking role, but also has an internal waterway built-in, which is connected with the waterway system of the dishwasher and is specially used for the drainage of the upper washing cavity. Such a layout greatly improves the drainage efficiency, so that the cleaning water in the upper washing cavity can fall on the partition member under the action of gravity, and then be discharged through the internal waterway, so as to quickly discharge the cleaned water, reduce the retention and waste of water resources, and further shorten the cleaning cycle, so that the overall cleaning efficiency of the dishwasher is significantly improved.

[0048] 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 related listed items.

[0049] The dishwasher is an equipment for automatically cleaning dishes, chopsticks, plates, dishes, knives and forks. The full-automatic dishwasher on the market can be divided into household and commercial types. The household full-automatic dishwasher is only suitable for home use, mainly including cabinet type, table type, sink integrated type and integrated type.

[0050] In the related art, the existing dishwasher has certain limitations in dealing with different cleaning needs. Specifically, the existing dishwasher often adopts a unified cleaning strategy and consumes the same amount of water and electricity. This approach is particularly unreasonable when the dishwasher is used to clean a small amount of tableware or tableware with light oil stains, as it not only leads to waste of water resources and electricity, but also makes the cleaning process seem lengthy.

[0051] To solve the above problems, please refer to Figures 1-2 The dishwasher 100 according to the present application includes a cabinet 10, a waterway system 20, and a partition member 30.

[0052] The waterway system 20 is arranged in the cabinet 10. The bottom of the cabinet 10 can be provided with a mounting cavity 13. The waterway system 20 includes a water inlet valve 23, a breather 24, a water softener 25, a water cup 26, a washing pump 27, and a drainage pump 28 mounted in the mounting cavity 13. The water inlet valve 23, the breather 24, the water softener 25, and the water cup 26 are sequentially connected. The washing pump 27 and the drainage pump 28 are both connected with the water cup 26.

[0053] The water inlet valve 23 serves as the inlet of the water source and is responsible for controlling the entry of the water flow. The breather 24 plays multiple roles, not only effectively discharging the hot air generated inside the dishwasher 100 to prevent heat accumulation and ensure the stability and safety of the washing process, but also has the functions of water inlet diversion and storage to ensure smooth distribution of the water flow. The water softener 25 is responsible for softening the water source entering the dishwasher 100, reducing the generation of scale, improving the washing effect, and protecting the internal components of the dishwasher 100. The water cup 26, as an important node in the waterway system 20, connects the water inlet valve 23, the breather 24, the water softener 25, and the subsequent washing pump 27 and drainage pump 28, and plays a role in transferring and storing water. The washing pump 27 delivers the water in the water cup 26 to the spraying system of the dishwasher 100 through pressurization to achieve powerful cleaning of the tableware. The drainage pump 28 is responsible for efficiently discharging the sewage generated after washing from the inside of the water cup 26. It has various types, including impeller pumps, diaphragm pumps, and vacuum pumps, each with its unique advantages and application scenarios, such as the high efficiency and large flow of impeller pumps, the self-priming ability and ability to handle impure liquids of diaphragm pumps, and the ability of vacuum pumps to create a negative pressure environment for efficient drainage in specific environments.

[0054] The separation member 30 is sealingly connected with the cavity wall of the cabinet 10 to separate the inner cavity of the cabinet 10 into the upper washing cavity 11 and the lower washing cavity 12. The separation member 30 can be plate-shaped or other shapes that can effectively separate the space. The sealing connection not only ensures that the water flow, detergent and dirt in the washing process do not penetrate between the upper washing cavity 11 and the lower washing cavity 12, thereby ensuring the efficiency and hygiene standard of washing, but also effectively separates the space through the close fit of the separation member 30 and the cavity wall of the cabinet 10.

[0055] It should be noted that the implementation of such sealing connection is various and flexible. On the one hand, the separation member 30 can be directly attached to the cavity wall of the cabinet 10, and through accurate size design and manufacturing process, the close contact between the two is ensured, thereby achieving the sealing effect. On the other hand, in order to further enhance the sealing performance, the separation member 30 and the cavity wall of the cabinet 10 can also be connected by means of sealant. The addition of sealant not only effectively fills the small gaps between the separation member 30 and the cavity wall of the cabinet 10, preventing water, detergent and dirt from penetrating during the washing process, but also enhances the stability and durability of the connection, ensuring that the separation member 30 does not loosen or fall off during long-term use.

[0056] The volumes of the upper washing cavity 11 and the lower washing cavity 12 are not equal. Specifically, the volume of the upper washing cavity 11 can be smaller than that of the lower washing cavity 12, for example, the volume ratio of the upper washing cavity 11 to the lower washing cavity 12 can be, for example, 4:6 or 3:7. In actual use, the smaller volume upper washing cavity 11 can be used to wash utensils such as small trays, chopsticks, knives and forks, cups, bowls, etc., while the larger volume lower washing cavity 12 can be used to wash bowls and pots with larger diameters, etc. In addition, the upper washing cavity 11 carries less utensils, reducing the weight of the upper part of the dishwasher 100 and preventing the risk of tipping due to excessive weight. It should be noted that in other embodiments of the dishwasher 100, the volume of the upper washing cavity 11 can be greater than that of the lower washing cavity 12 to facilitate the placement and removal of utensils.

[0057] In one embodiment, the cavity wall of the cabinet 10 is provided with a groove (not shown), which not only optimizes the internal space layout, but also provides precise positioning and support for the installation of the separation member 30. The separation member 30 is embedded in the groove, and the separation member 30 is adhesively or screw-connected with the inner wall of the cabinet 10. This connection method not only effectively prevents the penetration of water flow, detergent and dirt during washing, but also ensures the stability and durability of the separation member 30 during long-term use.

[0058] In another embodiment, the cabinet 10 further comprises support members (not shown) connected to the cavity wall of the cabinet 10, which are firmly connected to the cavity wall of the cabinet 10 to provide additional support and fixing points for the partition member 30. The partition member 30 is bonded or screwed to the support members. This design not only increases the flexibility of the installation of the partition member 30, but also makes the connection between the partition member 30 and the cabinet 10 more firm and reliable, further improving the overall performance and service life of the dishwasher 100.

[0059] The partition member 30 is provided with an internal waterway (not shown) that communicates with the waterway system 20 to be used for draining the upper washing cavity 11. The internal waterway can be flexibly extended in the horizontal or vertical direction inside the partition member 30 according to actual needs to adapt to the drainage requirements of different washing cavities.

[0060] The dishwasher 100 according to the embodiments of the present application realizes effective layering of the cavity of the cabinet 10 by providing the partition member 30, forming the upper washing cavity 11 and the lower washing cavity 12 that are independent of each other. This design allows the cleaning of tableware in the upper washing cavity 11 to be completely isolated from the cleaning in the lower washing cavity 12, avoiding the mutual influence of the cleaning water flow. At the same time, since the volumes of the upper washing cavity 11 and the lower washing cavity 12 are not equal, the actual number of tableware can be used to flexibly select which washing cavity to use for cleaning. The smaller upper washing cavity 11 is suitable for cleaning a smaller amount or smaller tableware, while the larger lower washing cavity 12 is more suitable for accommodating a large amount or larger tableware. This design not only ensures the cleaning effect, but also significantly saves water resources and energy consumption, because the entire washing system does not need to be started when cleaning a small batch of tableware, thereby reducing unnecessary energy consumption. At the same time, this also shortens the cleaning cycle, further improving the overall cleaning efficiency and energy utilization rate of the dishwasher 100.

[0061] In addition, the partition member 30 not only plays a blocking role, but also has an internal waterway built therein that communicates with the waterway system 20 of the dishwasher 100 and is specially used for the drainage of the upper washing cavity 11. Such a layout greatly improves the drainage efficiency, so that the cleaning water of the upper washing cavity 11 can fall onto the partition member 30 under the action of gravity, and then be drained through the internal waterway to quickly drain the cleaned water, reduce the retention and waste of water resources, and further shorten the cleaning cycle, so that the overall cleaning efficiency of the dishwasher 100 is significantly improved.

[0062] Reference Figures 1-3In some structural forms, the upper surface of the partition member 30 is provided with a water outlet 31 communicating with the internal water channel, and the water outlet 31 is arranged at the lowest point of the upper surface of the partition member 30. In this way, the water outlet 31 is positioned at the lowest point of the upper surface of the partition member 30. This arrangement ensures that the water accumulated in the upper washing cavity 11 can flow smoothly into the water outlet 31 and be effectively drained along the internal water channel, thereby maintaining the cleanliness and dryness of the upper washing cavity 11.

[0063] Further, the upper surface of the partition member 30 gradually decreases from the side away from the water outlet 31 to the side close to the water outlet 31. When the dishwasher 100 is in operation, a certain amount of water and dirt will accumulate in the upper washing cavity 11. In such a situation, the inclined design of the upper surface of the partition member 30 plays a key role. It guides the water and dirt in the upper washing cavity 11 along this gradually decreasing slope, naturally flowing towards the water outlet 31. This process not only reduces the possibility of water flow obstruction, but also significantly improves the speed and efficiency of drainage. In addition, this inclined design has additional advantages. Since water and dirt can be smoothly drained, there is almost no water accumulation in the upper washing cavity 11, which helps to maintain the cleanliness and hygiene of the upper washing cavity 11. In the long run, this will have a positive impact on the overall performance and life of the dishwasher 100, and also provide users with a more quality and efficient washing experience.

[0064] Referring to Figure 3 Optionally, the upper surface of the partition member 30 is further recessed to form a water passing groove 32, and the water outlet 31 is arranged at the groove bottom of the water passing groove 32. The groove bottom of the water passing groove 32 is the position of the water outlet 31. Such a layout allows water and dirt accumulated on the upper surface of the partition member 30 during the washing process to flow directly into the water passing groove 32, and then be smoothly drained through the water outlet 31. This process not only reduces the residence time of water flow on the surface of the partition member 30, but also reduces the risk of water accumulation, thereby maintaining the cleanliness and dryness of the upper washing cavity 11. In addition, the design of the water passing groove 32 also takes into account the dynamic characteristics of water flow. When the water flow enters the water passing groove 32, its flow path is effectively guided and optimized. This not only improves the speed and efficiency of drainage, but also reduces the scouring and abrasion of water flow on the surface of the partition member 30, thereby prolonging the service life of the dishwasher 100.

[0065] In an embodiment, the distance between the drain 31 and the rear wall of the upper washing cavity 11 is less than the distance between the drain 31 and the front wall of the upper washing cavity 11. It can be understood that during the washing process, water and dirt will often accumulate in the upper washing cavity 11 and move under the action of various forces. By arranging the drain 31 closer to the rear wall, the accumulated water and dirt can be more effectively guided to the drain 31, thereby accelerating the drainage speed and reducing the water accumulation. In addition, this design also takes into account the overall layout and usage habits of the upper washing cavity 11. The rear wall is usually hidden and not easily observed and contacted by the user, so arranging the drain 31 here will not interfere with the normal use of the user and will not affect the aesthetics of the upper washing cavity 11.

[0066] Further, the thickness of the partition member 30 gradually decreases from front to back along the cabinet 10. Since the front of both the upper and lower washing cavities is provided with a feeding opening for the user to feed the tableware, the thickness of the front of the partition member 30 is specially designed to be small. This design decision not only conforms to the principle of ergonomics, but also greatly improves the user's experience. The smaller thickness of the partition member 30 makes the feeding opening more spacious, and the user can more easily feed and take out the tableware without worrying about the inconvenience caused by the narrow space.

[0067] Referring to Figure 3 In an embodiment, the dishwasher 100 further comprises a filter member 50 embedded in the drain 31 and located in the internal waterway. The main function of the filter member 50 is to filter and intercept food residues, oil and other dirt generated during the washing process to prevent them from entering the drainage system with the water flow, thereby keeping the interior of the dishwasher 100 clean and the waterway unobstructed. By embedding the filter member 50 in the drain 31 and deep into the internal waterway, it is ensured that all the water flowing through it is effectively filtered, greatly reducing the risk of failure caused by dirt clogging the drain 31 or the waterway. In addition, the embedded design of the filter member 50 also brings another benefit: it simplifies the cleaning and maintenance work of the user. The user can easily remove the filter for cleaning or replacement without disassembling complex components, thereby prolonging the service life of the dishwasher 100 and improving the overall satisfaction of the user.

[0068] In combination with reference to FIG. Figure 1 , Figure 2 and Figure 4In an embodiment, the waterway system 20 includes a first drain pipe 21 arranged in the lower washing cavity 12 and attached to the lower surface of the partition member 30 and the cavity wall surface of the lower washing cavity 12, and the first drain pipe 21 is in communication with the drain port 31 through the internal waterway. Such a layout not only optimizes the space utilization and drainage efficiency, but also takes into account the convenience of maintenance. Since the position of the first drain pipe 21 is relatively fixed and easy to access, when maintenance or inspection is needed, the technician can more easily access the first drain pipe 21 without the need for complex disassembly or movement of other components. Such a design makes the maintenance work more efficient, reduces the downtime caused by maintenance, and thus ensures the stability and reliability of the entire waterway system 20.

[0069] With reference to Figures 2-4 In some structural forms, the dishwasher 100 further includes a first water inlet pipe 22 and a first spraying member 40, and the internal waterway is in communication with the waterway system 20 through the first water inlet pipe 22. The first spraying member 40 is connected to the upper surface of the partition member 30 and is in communication with the internal waterway to spray and rinse the upper washing cavity 11. Among them, the first water inlet pipe 22 serves as a bridge connecting the washing pump 27 of the waterway system 20 and the internal waterway of the partition member 30, ensuring that the cleaning water can smoothly pass through the internal waterway of the partition member 30, thereby flowing to the first spraying member 40 to provide the necessary water resources for the washing process. At the same time, the first spraying member 40 is installed on the upper surface of the partition member 30 and is closely connected to the internal waterway, forming an efficient water flow circulation system. This design enables the first spraying member 40 to spray and rinse from above the upper washing cavity 11, using water flow to clean the tableware in all directions, thereby greatly improving the washing effect and efficiency. Through such structural configuration, the dishwasher 100 not only realizes deep cleaning of tableware, but also ensures the stability and reliability of the washing process. It should be noted that the number of first water inlet pipes 22 can be two, and the two first water inlet pipes 22 are respectively in communication with the internal waterway of the partition member 30 to improve the cleaning efficiency.

[0070] With reference to Figures 5-7Further, the first spraying member 40 comprises a spraying cover plate 41 installed on the upper surface of the partition member 30, and the spraying cover plate 41 is provided with a plurality of spray holes 411 in communication with the internal water channel. In order to further optimize the washing performance, the first spraying member 40 is designed to include the spraying cover plate 41 as a component. The spraying cover plate 41 is stably installed on the upper surface of the partition member 30, and such an arrangement not only ensures its stability, but also facilitates uniform and comprehensive spraying of the tableware in the upper washing cavity 11. The spraying cover plate 41 is carefully provided with a plurality of spray holes 411, which are not only moderately in number and uniformly distributed, but also closely connected with the internal water channel to form a complete water flow circulation system. When the dishwasher 100 is started, the cleaning water is transported to the spraying cover plate 41 through the internal water channel and sprayed out of the spray holes 411 at high speed to form a powerful water flow impact force for deep cleaning of the surface of the tableware. Such a design not only improves the washing efficiency, but also ensures the uniformity and thoroughness of the washing process, providing users with a more excellent washing experience.

[0071] It should be noted that the stable connection between the spraying cover plate 41 and the partition member 30 can be fixed in a detachable manner such as screw fixing and buckle connection. The screw fixing method fixes the spraying cover plate 41 on the partition member 30 by pre-providing suitable threaded holes on the upper surface of the partition member 30, and then aligning the position of the spraying cover plate 41 and using screws to fasten it on the partition member 30. This fixing method has the advantages of simple structure and firm connection, and can ensure that the spraying cover plate 41 does not shift or loosen during the washing process, thereby ensuring the stability of the water flow and the accuracy of the spraying. The buckle connection method matches the buckle part on the spraying cover plate 41 with the buckle groove on the partition member 30 by using the elastic deformation principle of the buckle structure, and the tight connection of the two can be achieved by simple pressing or rotating action. This fixing method is not only simple to operate, but also does not require the use of additional fasteners, reducing the installation cost. At the same time, the buckle connection also has a certain self-locking property, which can prevent the spraying cover plate 41 from accidentally falling off during the washing process to a certain extent.

[0072] For reference Figure 8 Further, the first spraying member 40 further comprises a spraying arm 42 movably connected to the upper surface of the partition member 30, and the spraying arm 42 is provided with a spraying hole 421 in communication with the internal water channel, and the spraying arm 42 is arranged in a staggered manner with the spray hole 411.

[0073] The spray arm 42 is designed to be movably connected to the upper surface of the partition member 30, which allows it to rotate or swing to a certain extent during the washing process, ensuring that the water flow can more comprehensively cover the corners of the upper washing cavity 11. The spray arm 42 is also provided with spray holes 421 that communicate with the internal waterway, which are staggered with the spray holes 411 on the spray cover plate 41 to avoid repeated and blind areas of water jet. When the cleaning water is transported to the spray arm 42 through the internal waterway, it will be sprayed out at a certain angle and speed from the spray holes 421, forming a powerful water flow impact force to deeply clean the tableware. Due to the mobility of the spray arm 42, the water flow can constantly change direction and angle with the rotation or swing of the spray arm, thereby achieving all-around flushing and washing of the surface of the tableware. Such a design not only improves the washing efficiency, but also ensures the uniformity and thoroughness of washing. Through the synergistic effect of the spray cover plate 41 and the spray arm 42, the dishwasher 100 can achieve three-dimensional cleaning of the tableware, whether it is the surface of the tableware or the hard-to-reach gaps can be fully flushed and washed. Such an advanced design brings users a more excellent washing effect and use experience.

[0074] Further, the spray arm 42 is located in the middle of the upper surface of the partition member 30, and the plurality of spray holes 411 are located between the boundary of the spray arm 42 and the partition member 30. Specifically, the spray arm 42 is cleverly placed in the middle of the upper surface of the partition member 30, which ensures that it can uniformly distribute water flow in multiple directions within the washing cavity. Whether the tableware is located in the center or the edge, it can be fully cleaned within the spray range of the spray arm 42. At the same time, the plurality of spray holes 411 are carefully arranged between the boundary of the spray arm 42 and the partition member 30. These spray holes 411 not only have a moderate number, but also are uniformly distributed, and they communicate with the internal waterway. When the dishwasher 100 is started, the cleaning water will be sprayed out at a certain speed and angle through these spray holes 411, forming a powerful water flow impact force. Since the spray holes 411 are located at the boundary of the spray arm 42 and the partition member 30, such a layout enables the water flow to more smoothly cover every corner of the washing cavity, avoiding blind areas and repeated areas of water jet. Such a design not only improves the washing efficiency, but also ensures the uniformity and thoroughness of washing. Through the rotation of the spray arm 42 and the precise layout of the spray holes 411, the dishwasher 100 can achieve comprehensive flushing and washing of the tableware, to have a more excellent cleaning effect and use experience.

[0075] Further, the plurality of spray holes 411 are located on the same side of the spray arm 42 and arranged along the front-to-rear direction of the cabinet 10. It is to be noted that the following description of the direction is defined with respect to the position of the dishwasher 100 relative to the user, i.e. the side of the dishwasher 100 facing the user is the front side, and the side of the dishwasher 100 facing away from the user is the rear side. Such a layout design means that when the dishwasher 100 is started, the cleaning water will be sprayed out from each of the spray holes 411 along the side of the spray arm 42 from front to rear. Such a water flow path not only ensures that the dishes in the front of the washing cavity can be fully cleaned, but also ensures that the dishes in the rear will not be cleaned thoroughly due to insufficient water flow. Since the spray holes 411 are arranged along the direction of the cabinet 10, the water flow can more evenly cover multiple areas in the washing cavity, avoiding washing blind spots and improving the uniformity and thoroughness of washing. In addition, such a layout of the spray holes 411 also helps to enhance the scouring force of the water flow. When the water flow is sprayed out from the plurality of spray holes 411 at the same time, they will form a dynamic water flow field in the washing cavity, which can scour and wash the surface of the dishes in all directions, thereby more effectively removing stains and residues. In general, the ingenious layout of the spray holes 411 on the spray arm 42 not only improves the washing efficiency, but also ensures the uniformity and thoroughness of washing, bringing users a more excellent cleaning effect and use experience.

[0076] By way of reference Figure 9 Optionally, the spray holes 411 include first sub-holes 4111 and second sub-holes 4112, the plurality of first sub-holes 4111 are located on one side of the spray arm 42 and arranged along the front-to-rear direction of the cabinet 10, and the plurality of second sub-holes 4112 are located on the opposite side of the spray arm 42 and arranged along the front-to-rear direction of the cabinet 10. The plurality of first sub-holes 4111 are carefully arranged on one side of the spray arm 42, which are arranged along the front-to-rear direction of the cabinet 10, forming a continuous water flow path. Similarly, the plurality of second sub-holes 4112 are also ingeniously arranged on the opposite side of the spray arm 42, and are also arranged along the front-to-rear direction of the cabinet 10, forming a symmetrical layout with the first sub-holes 4111. Such a design ensures that whether it is the dishes in the front or the dishes in the rear of the washing cavity, they can be fully scoured and washed by the water flow from both sides, thereby improving the uniformity and thoroughness of washing.

[0077] In addition, this symmetrical layout of the first sub-holes 4111 and the second sub-holes 4112 also helps to enhance the scouring power and coverage of the water flow. When the dishwasher 100 is started, cleaning water will be sprayed out from both the first sub-holes 4111 and the second sub-holes 4112 simultaneously, forming two interlaced water flow paths. These two water flow paths collide and interweave with each other inside the washing cavity, forming a dynamic and complex water flow field. This water flow field can provide more comprehensive and in-depth scouring and washing to the surface of the tableware, thereby more effectively removing stains and residues. In general, the spray hole 411 is designed to contain two types of first sub-holes 4111 and second sub-holes 4112, and these two types of sub-holes are respectively located on opposite sides of the spray arm 42 and arranged along the direction of the cabinet 10. Such innovative design not only improves the washing efficiency, but also ensures the uniformity and thoroughness of washing, thereby improving the cleaning effect and user experience.

[0078] With reference to Figure 2 In the overall design of the dishwasher 100, in addition to the components mentioned earlier, it also additionally contains a second water inlet pipe 29b, a second water outlet pipe 29a, and a second spray member 60. The addition of these components further enriches the functions and performance of the dishwasher 100. At the same time, the waterway system 20 has also been correspondingly expanded, adding the key component of the water distribution valve 29.

[0079] Specifically, the second water inlet pipe 29b serves as another water source input channel and works in parallel with the first water inlet pipe 22 to jointly provide cleaning water for the dishwasher 100. Both of these two water inlet pipes are connected to the washing pump 27 through the water distribution valve 29, which plays a role in distributing and adjusting the water flow, ensuring that the water flow of the two water inlet pipes can be distributed to the washing pump 27 as needed, and then delivered to each spray member. The second water outlet pipe 29a is responsible for draining the wastewater in the second washing cavity, and it is connected to the water cup 26, forming a complete wastewater recovery and treatment system. When the washing process is completed, the wastewater in the second washing cavity will flow into the water cup 26 through the second water outlet pipe 29a, waiting for further discharge or treatment. The second spray member 60, as another important washing component, is designed in the second washing cavity and connected to the second water inlet pipe 29b. In this way, when the second water inlet pipe 29b receives cleaning water, these waters will be sprayed out through the second spray member 60 at a certain speed and angle to scour and wash the tableware in the second washing cavity. Such design not only improves the washing efficiency, but also ensures the uniformity and thoroughness of washing. It can be understood that the structure of the second spray member 60 can be the same as that of the first spray member 40, which is the structure of the spray arm.
