Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a dishwasher. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet type, countertop type, sink-integrated type, and integrated type.

[0003] In related technologies, existing dishwashers have certain limitations in dealing with different cleaning needs. Specifically, existing dishwashers often adopt a uniform cleaning strategy and consume the same amount of water and electricity. This approach is particularly unreasonable when the dishwasher is only used to clean a small number of dishes or lightly soiled dishes, because it not only wastes water and electricity, resulting in resource waste, but also makes the cleaning process lengthy. Summary of the Invention

[0004] This application provides a dishwasher that can save water and electricity, shorten washing time, and improve the washing efficiency of the dishwasher when washing a small number of dishes or lightly oily dishes. At the same time, it can directly set an internal water channel in the partition component to drain the upper washing chamber, thereby improving drainage efficiency.

[0005] This application provides a dishwasher, which includes:

[0006] Cabinet;

[0007] A water system, wherein the water system is located within the cabinet; and

[0008] A partition member is provided, which is sealed to the cavity wall of the cabinet to divide the inner cavity of the cabinet into an independent upper washing cavity and a lower washing cavity. The upper washing cavity and the lower washing cavity have different volumes. The partition member is provided with an internal water passage, which is connected to the water passage system so that the internal water passage is used to drain the upper washing cavity.

[0009] In some embodiments, the upper surface of the partition member is provided with a drain outlet that communicates with the internal water passage, and the drain outlet is located at the lowest point of the upper surface of the partition member.

[0010] In some embodiments, the upper surface of the partition member gradually decreases from the side away from the drain outlet to the side closer to the drain outlet.

[0011] In some embodiments, the upper surface of the partition member is further recessed to form a water passage groove, and the drain outlet is located at the bottom of the water passage groove.

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

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

[0014] In some embodiments, the dishwasher further includes a filter element embedded in the drain outlet and located within the internal water passage.

[0015] In some embodiments, the water system includes a first drain pipe disposed within the lower washing chamber and attached to the lower surface of the partition member and the wall of the lower washing chamber. The first drain pipe is connected to the drain outlet through the internal water passage.

[0016] In some embodiments, the dishwasher further includes a first water inlet pipe and a first spray component, and the internal water passage is connected to the water passage system through the first water inlet pipe;

[0017] The first spray component is connected to the upper surface of the partition component and communicates with the internal water channel to spray and rinse the upper washing chamber.

[0018] In some embodiments, the first spraying component includes a spray cover plate, which is mounted on the upper surface of the partition component. The spray cover plate is provided with a plurality of spray holes, which are connected to the internal water passage.

[0019] In some embodiments, the first spraying component further includes a spraying arm, which is movably connected to the upper surface of the partition component, and the spraying arm is provided with spraying holes communicating with the internal water passage, and the spraying arm and the spraying holes are misaligned.

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

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

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

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

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

[0025] In some embodiments, the volumes of the upper washing chamber and the lower washing chamber are not equal.

[0026] In some embodiments, the front side of the cabinet has a first dispensing port communicating with the upper washing chamber and a second dispensing port communicating with the lower washing chamber;

[0027] The dishwasher also includes:

[0028] The first door is movably connected to the cabinet to close or open the first dispensing port; and

[0029] The second door is movably connected to the cabinet to close or open the second delivery port.

[0030] The dishwasher based on this application embodiment achieves effective layering of the cabinet cavity by setting a partition component, forming independent upper and lower washing chambers. This design completely isolates the washing of dishes in the upper washing chamber from the washing in the lower washing chamber, avoiding mutual interference of washing water flow. Simultaneously, since the upper and lower washing chambers have unequal volumes, the washing chamber can be flexibly selected based on the actual quantity of dishes. The smaller upper washing chamber is suitable for washing smaller quantities or smaller dishes, while the larger lower washing chamber is better suited for accommodating larger quantities or larger dishes. This design not only ensures cleaning effectiveness but also significantly saves water and electricity consumption, as the entire washing system does not need to be started when washing small batches of dishes, thus reducing unnecessary energy consumption. Furthermore, this shortens the washing cycle, further improving the overall cleaning efficiency and energy utilization rate of the dishwasher.

[0031] Furthermore, the partition not only serves as a barrier, but its built-in internal water channels are also connected to the dishwasher's water system, specifically for draining the upper washing chamber. This layout greatly improves drainage efficiency, allowing the washing water in the upper washing chamber to fall onto the partition under gravity and then be discharged through the internal water channels, quickly removing the washed water and reducing water retention and waste. It also further shortens the washing cycle, significantly improving the overall cleaning efficiency of the dishwasher. Attached Figure Description

[0049] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet type, countertop type, sink-integrated type, and integrated type.

[0050] In related technologies, existing dishwashers have certain limitations in dealing with different cleaning needs. Specifically, existing dishwashers often adopt a uniform cleaning strategy and consume the same amount of water and electricity. This approach is particularly unreasonable when the dishwasher is only used to clean a small number of dishes or lightly soiled dishes, because it not only wastes water and electricity, resulting in resource waste, but also makes the cleaning process lengthy.

[0051] To resolve the above issues, please refer to [link / reference]. Figures 1 to 2 This application proposes a dishwasher 100, which, in the embodiments of this application, includes a cabinet 10, a water system 20, and a partition member 30.

[0052] The water system 20 is located in the cabinet 10. The bottom of the cabinet 10 may have an installation cavity 13. The water system 20 includes an inlet valve 23, a breather 24, a water softener 25, a water cup 26, a washing pump 27, and a drain pump 28 installed in the installation cavity 13. The inlet valve 23, the breather 24, the water softener 25, and the water cup 26 are connected in sequence. The washing pump 27 and the drain pump 28 are both connected to the water cup 26.

[0053] The inlet valve 23, acting as the water source inlet, controls the water flow. The breather 24 plays multiple roles, effectively expelling hot air generated inside the dishwasher 100 to prevent heat buildup and ensure the stability and safety of the washing process. It also functions as a water inlet / outlet distributor and storage unit, ensuring smooth water distribution. The water softener 25 softens the water entering the dishwasher 100, reducing limescale buildup, improving washing performance, and protecting the internal components of the dishwasher 100. The water cup 26, a crucial node in the water system 20, connects the inlet valve 23, breather 24, water softener 25, and subsequent washing pump 27 and drain pump 28, serving as a water transfer and storage unit. The washing pump 27 pressurizes the water in the water cup 26 and delivers it to the dishwasher 100's spray system for powerful cleaning of the dishes. The drain pump 28 is responsible for efficiently discharging the wastewater generated after washing from inside the water cup 26. It comes in various types, including impeller pumps, diaphragm pumps, and vacuum pumps. Each type of pump has its unique advantages and application scenarios, such as the high efficiency and large flow rate of impeller pumps, the self-priming ability and ability to handle impurity liquids of diaphragm pumps, and the ability of vacuum pumps to create a negative pressure environment to achieve efficient drainage under specific conditions.

[0054] The partition member 30 is sealed to the cavity wall of the cabinet 10 to divide the inner cavity of the cabinet 10 into two independent washing chambers: an upper washing chamber 11 and a lower washing chamber 12. The partition member 30 can be plate-shaped or other shapes that effectively divide space. This sealed connection not only ensures that water, detergent, and dirt do not permeate between the upper washing chamber 11 and the lower washing chamber 12 during the washing process, thus guaranteeing washing efficiency and hygiene standards, but also achieves effective space division through the tight fit between the partition member 30 and the cavity wall of the cabinet 10.

[0055] It should be noted that this sealing connection can be achieved in various and flexible ways. On the one hand, the partition member 30 can be directly attached to the cavity wall of the cabinet 10. Through precise dimensional design and manufacturing process, a tight contact between the two is ensured, thereby achieving a sealing effect. On the other hand, to further enhance the sealing performance, the partition member 30 and the cavity wall of the cabinet 10 can also be connected using sealant. The addition of sealant can not only effectively fill the tiny gaps between the partition member 30 and the cavity wall of the cabinet 10, preventing water, detergent, and dirt from seeping in during the washing process, but also enhance the stability and durability of the connection, ensuring that the partition member 30 will not loosen or fall off during long-term use.

[0056] The upper washing chamber 11 and the lower washing chamber 12 have unequal volumes. Specifically, the volume of the upper washing chamber 11 can be smaller than the volume of the lower washing chamber 12. For example, the ratio of the volume of the upper washing chamber 11 to the volume of the lower washing chamber 12 can be 4:6 or 3:7. In actual use, the smaller upper washing chamber 11 is suitable for washing small dishes, chopsticks, knives, forks, cups, small bowls, etc., while the larger lower washing chamber 12 can be used for washing bowls and pots with larger diameters. Furthermore, the upper washing chamber 11 carries fewer dishes, reducing the weight of the upper part of the dishwasher 100 and preventing the risk of tipping over due to excessive weight. Of course, it should be noted that in other embodiments of the dishwasher 100, the volume of the upper washing chamber 11 can also be larger than the volume of the lower washing chamber 12 to facilitate the loading and unloading of dishes.

[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 partition member 30. The partition member 30 is embedded in the groove and is bonded or screwed to the inner wall surface of the cabinet 10. This connection method not only effectively prevents water, detergent, and dirt from penetrating during the washing process but also ensures the stability and durability of the partition member 30 during long-term use.

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

[0059] The partition member 30 is provided with an internal water passage (not shown), which is connected to the water system 20 so that the internal water passage is used to drain the upper washing chamber 11. The internal water passage can extend flexibly in the horizontal or vertical direction inside the partition member 30 as needed to adapt to the drainage requirements of different washing chambers.

[0060] The dishwasher 100 based on this application embodiment achieves effective layering of the inner cavity of the cabinet 10 by setting the partition member 30, forming an independent upper washing chamber 11 and a lower washing chamber 12. This design completely isolates the washing of dishes in the upper washing chamber 11 from the washing in the lower washing chamber 12, avoiding mutual interference of washing water flow. Simultaneously, since the volumes of the upper washing chamber 11 and the lower washing chamber 12 are unequal, the washing chamber can be flexibly selected according to the actual quantity of dishes. The smaller upper washing chamber 11 is suitable for washing a smaller quantity or smaller dishes, while the larger lower washing chamber 12 is more suitable for accommodating a larger quantity or larger dishes. This design not only ensures cleaning effect but also significantly saves water and electricity consumption, as the entire washing system does not need to be started when washing a small batch of dishes, thus reducing unnecessary energy consumption. At the same time, this also shortens the washing cycle, further improving the overall cleaning efficiency and energy utilization rate of the dishwasher 100.

[0061] Furthermore, the partition member 30 not only serves as a barrier, but its built-in internal water passage is also connected to the water system 20 of the dishwasher 100, specifically for draining water from the upper washing chamber 11. This layout greatly improves drainage efficiency, allowing the washing water in the upper washing chamber 11 to fall onto the partition member 30 under gravity and then be discharged through the internal water passage, quickly removing the washed water, reducing water retention and waste, and further shortening the washing cycle, thus significantly improving the overall cleaning efficiency of the dishwasher 100.

[0062] Reference Figures 1 to 3In some structural configurations, the upper surface of the partition member 30 is provided with a drain outlet 31 that connects to the internal water passage, and the drain outlet 31 is located at the lowest point of the upper surface of the partition member 30. By positioning the drain outlet 31 at the lowest point of the upper surface of the partition member 30, this arrangement ensures that water accumulated in the upper washing chamber 11 can smoothly flow into the drain outlet 31 and be effectively discharged along the internal water passage, thereby maintaining the cleanliness and dryness of the upper washing chamber 11.

[0063] Furthermore, the upper surface of the partition member 30 gradually slopes down from the side furthest from the drain outlet 31 to the side closest to it. When the dishwasher 100 is running, a certain amount of water and dirt accumulates in the upper washing chamber 11. In this situation, the inclined design of the upper surface of the partition member 30 plays a crucial role. It guides the water and dirt in the upper washing chamber 11 along this gradually decreasing slope, naturally flowing towards the drain 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 brings additional advantages. Because water and dirt can drain smoothly, there is almost no water residue in the upper washing chamber 11, which helps maintain the cleanliness and hygiene of the upper washing chamber 11. In the long run, this will have a positive impact on the overall performance and lifespan of the dishwasher 100, while also providing users with a higher quality and more efficient washing experience.

[0064] Reference Figure 3 Optionally, the upper surface of the partition member 30 is further recessed to form a water-passing groove 32, with a drain outlet 31 located at the bottom of the water-passing groove 32. The bottom of the water-passing groove 32 is precisely where the drain outlet 31 is located. This arrangement allows water and dirt accumulating on the upper surface of the partition member 30 during washing to flow directly into the water-passing groove 32 and then be smoothly discharged through the drain outlet 31. This process not only reduces the residence time of water on the surface of the partition member 30 but also reduces the risk of water residue, thereby keeping the upper washing chamber 11 clean and dry. In addition, the design of the water-passing groove 32 also takes into account the dynamic characteristics of water flow. When water 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 wear of water on the surface of the partition member 30, thereby extending the service life of the dishwasher 100.

[0065] In one embodiment, the distance between the drain outlet 31 and the rear wall of the upper washing chamber 11 is less than the distance between the drain outlet 31 and the front wall of the upper washing chamber 11. It is understood that during the washing process, water and dirt tend to accumulate within the upper washing chamber 11 and move under various forces. By placing the drain outlet 31 closer to the rear wall of the chamber, the accumulated water and dirt can be guided to the drain outlet 31 more effectively, thereby accelerating drainage and reducing water residue. Furthermore, this design also considers the overall layout and usage habits of the upper washing chamber 11. The rear wall of the chamber is usually relatively concealed and not easily observed or touched by the user; therefore, placing the drain outlet 31 here will not interfere with normal use or affect the aesthetics of the upper washing chamber 11.

[0066] Furthermore, the thickness of the partition member 30 gradually decreases along the cabinet 10 from front to back. Since both the upper and lower washing chambers have inlets at the front for users to place tableware, the thickness of the partition member 30 at the front is specifically designed to be smaller. This design decision not only conforms to ergonomic principles but also greatly enhances the user experience. The smaller thickness of the partition member 30 makes the inlets wider, allowing users to more easily place and retrieve tableware without worrying about operational inconvenience caused by limited space.

[0067] Reference Figure 3 In one embodiment, the dishwasher 100 further includes a filter element 50, which is embedded in the drain outlet 31 and located within the internal water passage. The main function of the filter element 50 is to filter and intercept food residue, grease, and other contaminants generated during the washing process, preventing them from entering the drainage system with the water flow, thereby maintaining the cleanliness of the dishwasher 100's interior and ensuring unobstructed water flow. By embedding the filter element 50 in the drain outlet 31 and extending it deep into the internal water passage, all flowing water is effectively filtered, significantly reducing the risk of malfunctions caused by contaminants clogging the drain outlet 31 or the water passage. Furthermore, the embedded design of the filter element 50 offers another benefit: it simplifies cleaning and maintenance for the user. Users can easily remove the filter for cleaning or replacement without disassembling complex components, thus extending the lifespan of the dishwasher 100 and improving overall user satisfaction.

[0068] Referring to the reference Figure 1 , Figure 2 as well as Figure 4In one embodiment, the water system 20 includes a first drain pipe 21, which is disposed within the lower washing chamber 12 and affixed to the lower surface of the partition member 30 and the wall surface of the lower washing chamber 12. The first drain pipe 21 is connected to the drain outlet 31 via an internal water passage. This layout not only optimizes space utilization and drainage efficiency but also considers ease of maintenance. Since the position of the first drain pipe 21 is relatively fixed and easily accessible, technicians can easily access it during maintenance or inspection without complex disassembly or movement of other components. This design makes maintenance work more efficient, reduces downtime caused by maintenance, and thus ensures the stability and reliability of the entire water system 20.

[0069] Reference Figures 2 to 4 In some structural configurations, the dishwasher 100 also includes a first water inlet pipe 22 and a first spray component 40. The internal water passage is connected to the water system 20 via the first water inlet pipe 22. The first spray component 40 is connected to the upper surface of the partition member 30 and communicates with the internal water passage to spray and rinse the upper washing chamber 11. The first water inlet pipe 22 acts as a bridge connecting the washing pump 27 of the water system 20 and the internal water passage of the partition member 30, ensuring that cleaning water can smoothly pass through the internal water passage of the partition member 30 and flow to the first spray component 40, providing the necessary water resources for the washing process. Simultaneously, the first spray component 40 is installed on the upper surface of the partition member 30 and is tightly connected to the internal water passage, forming a highly efficient water circulation system. This design allows the first spray component 40 to spray and rinse from above the upper washing chamber 11, using water flow to clean the dishes from all angles, thereby greatly improving the washing effect and efficiency. Through this structural configuration, the dishwasher 100 not only achieves thorough cleaning of the dishes but also ensures the stability and reliability of the washing process. It should be noted that there can be two first water inlet pipes 22, and the two first water inlet pipes 22 are respectively connected to the internal water passage of the partition component 30 to improve cleaning efficiency.

[0070] Combined with reference Figures 5 to 7Furthermore, the first spray component 40 includes a spray cover plate 41, which is mounted on the upper surface of the partition component 30. The spray cover plate 41 has multiple spray holes 411, which are connected to the internal water channels. To further optimize washing performance, the first spray component 40 is designed to include the spray cover plate 41. The spray cover plate 41 is securely mounted on the upper surface of the partition component 30. This arrangement ensures stability and facilitates even and comprehensive spraying of the dishes in the upper washing chamber 11. The spray cover plate 41 is carefully provided with multiple spray holes 411. These spray holes 411 are not only of moderate number and evenly distributed, but also closely connected to the internal water channels, forming a complete water circulation system. When the dishwasher 100 is started, cleaning water is delivered to the spray cover plate 41 through the internal water channels and sprayed out at high speed from the spray holes 411, forming a powerful water jet impact force to deeply clean the surface of the dishes. This design not only improves washing efficiency but also ensures the uniformity and thoroughness of the washing process, bringing users a superior washing experience.

[0071] It should be noted that the secure connection between the spray cover 41 and the partition member 30 can be achieved through detachable methods such as screw fixing and snap-fit ​​connection. For screw fixing, suitable threaded holes are pre-set on the upper surface of the partition member 30, and then the spray cover 41 is aligned and fastened to the partition member 30 with screws. This fixing method has the advantages of simple structure and strong connection, ensuring that the spray cover 41 will not shift or loosen during washing, thus guaranteeing the stability of the water flow and the accuracy of the spray. The snap-fit ​​connection utilizes the elastic deformation principle of the snap-fit ​​structure, matching the snap-fit ​​part on the spray cover 41 with the snap-fit ​​groove on the partition member 30. A simple pressing or rotating action achieves a tight connection between the two. This fixing method is not only easy to operate but also eliminates the need for additional fasteners, reducing installation costs. Furthermore, the snap-fit ​​connection has a certain degree of self-locking, which can prevent the spray cover 41 from accidentally falling off during washing to some extent.

[0072] Combined with reference Figure 8 Furthermore, the first spraying component 40 also includes a spraying arm 42, which is movably connected to the upper surface of the partition component 30, and the spraying arm 42 is provided with a spraying hole 421 communicating with the internal water channel. The spraying arm 42 and the spraying hole 411 are misaligned.

[0073] The spray arm 42 is designed to be movably connected to the upper surface of the partition member 30. This design allows it to rotate or swing to a certain extent during the washing process, ensuring that the water flow can more comprehensively cover multiple corners within the upper washing chamber 11. The spray arm 42 also has spray holes 421 that communicate with the internal water channels. These spray holes 421 are offset from the spray holes 411 on the spray cover plate 41, avoiding repetitive water spraying and blind spots. When cleaning water is delivered to the spray arm 42 through the internal water channels, it is sprayed out from the spray holes 421 at a certain angle and speed, forming a powerful water jet impact for deep cleaning of the tableware. Due to the mobility of the spray arm 42, the direction and angle of these water jets can continuously change with the rotation or swing of the spray arm, thus achieving all-round rinsing and washing of the tableware surface. This design not only improves washing efficiency but also ensures the uniformity and thoroughness of the washing. Through the coordinated action of the spray cover 41 and the spray arms 42, the dishwasher 100 can achieve three-dimensional cleaning of tableware, thoroughly rinsing and washing both the surface of the tableware and hard-to-reach crevices. This advanced design brings users a superior washing effect and user experience.

[0074] Furthermore, the spray arm 42 is located in the center of the upper surface of the partition member 30, and multiple spray holes 411 are located between the spray arm 42 and the boundary of the partition member 30. Specifically, the spray arm 42 is cleverly positioned in the center of the upper surface of the partition member 30, a position that ensures it can evenly distribute water flow in multiple directions within the washing chamber. Whether the dishes are in the center or on the edge, they can be thoroughly cleaned within the spray range of the spray arm 42. Simultaneously, the multiple spray holes 411 are carefully arranged between the spray arm 42 and the boundary of the partition member 30. These spray holes 411 are not only of moderate number but also evenly distributed; they are connected to the internal water channels. When the dishwasher 100 starts, cleaning water is sprayed out through these spray holes 411 at a certain speed and angle, creating a powerful water jet impact. Because the spray holes 411 are located at the boundary of the spray arm 42 and the partition member 30, this layout allows the water flow to more smoothly cover every corner of the washing chamber, avoiding blind spots and repetitive areas of water spray. This design not only improves washing efficiency but also ensures even and thorough washing. Through the rotation of the spray arm 42 and the precise layout of the spray nozzles 411, the dishwasher 100 can achieve comprehensive rinsing and washing of the dishes, resulting in superior cleaning performance and user experience.

[0075] Furthermore, multiple spray nozzles 411 are located on the same side of the spray arm 42 and arranged along the cabinet 10 from front to back. It should be noted that the following description of direction is defined relative to the user's position; the side of the dishwasher 100 facing the user is the front side, and the side facing away from the user is the rear side. This layout design means that when the dishwasher 100 starts, cleaning water will spray out sequentially from the spray nozzles 411 along this side of the spray arm 42 from front to back. This water flow path not only ensures that the dishes at the front of the washing chamber are thoroughly cleaned, but also ensures that the dishes at the back are not left uncleaned due to insufficient water flow. Because the spray nozzles 411 are arranged along the direction of the cabinet 10, the water flow can more evenly cover multiple areas within the washing chamber, avoiding blind spots and improving the uniformity and thoroughness of washing. In addition, this spray nozzle layout also helps to enhance the rinsing force of the water flow. When water is sprayed simultaneously from multiple nozzles 411, they create a dynamic water flow field within the washing chamber. This flow field effectively rinses and washes the surface of the tableware, thus removing stains and residues more efficiently. In summary, the ingenious arrangement of the nozzles 411 on the spray arm 42 not only improves washing efficiency but also ensures uniform and thorough washing, providing users with a superior cleaning effect and user experience.

[0076] Combined with reference Figure 9 Optionally, the spray nozzle 411 includes a first sub-hole 4111 and a second sub-hole 4112. Multiple first sub-holes 4111 are located on one side of the spray arm 42 and arranged along the front to back of the cabinet 10. Multiple second sub-holes 4112 are located on the opposite side of the spray arm 42 and arranged along the front to back of the cabinet 10. The multiple first sub-holes 4111 are carefully positioned on one side of the spray arm 42, arranged along the front to back of the cabinet 10, forming a continuous water flow path. Similarly, multiple second sub-holes 4112 are cleverly arranged on the opposite side of the spray arm 42, also arranged along the front to back of the cabinet 10, forming a symmetrical layout with the first sub-holes 4111. This design ensures that both the front and back dishes in the washing chamber receive sufficient rinsing and washing from the water flow on both sides, thereby improving the uniformity and thoroughness of the washing.

[0077] Furthermore, the symmetrical layout of the first sub-hole 4111 and the second sub-hole 4112 helps to enhance the rinsing force and coverage of the water flow. When the dishwasher 100 starts, cleaning water is sprayed simultaneously from the first sub-hole 4111 and the second sub-hole 4112, forming two intersecting water flow paths. These two water flow paths collide and intertwine within the washing chamber, forming a dynamic and complex water flow field. This water flow field can more comprehensively and thoroughly rinse and wash the surface of the tableware, thereby more effectively removing stains and residues. In summary, the spray nozzle 411 is designed to include both the first sub-hole 4111 and the second sub-hole 4112, and these two types of sub-holes are located on opposite sides of the spray arm 42 and arranged along the direction of the cabinet 10. This innovative design not only improves washing efficiency but also ensures the uniformity and thoroughness of washing, thereby enhancing the cleaning effect and user experience.

[0078] Reference Figure 2 In addition to the previously mentioned components, the dishwasher 100's overall design also includes a second water inlet pipe 29b, a second drain pipe 29a, and a second spray component 60. The addition of these components further enriches the dishwasher 100's functionality and performance. Simultaneously, the water system 20 has also been expanded accordingly, with the addition of the crucial component, a water distribution valve 29.

[0079] Specifically, the second water inlet pipe 29b, as another water input channel, works in parallel with the first water inlet pipe 22 to provide cleaning water for the dishwasher 100. Both water inlet pipes are connected to the washing pump 27 via a water distribution valve 29, which distributes and regulates the water flow to ensure that the water from the two water inlet pipes is distributed to the washing pump 27 as needed, and then delivered to each spray component. The second drain pipe 29a is responsible for draining the wastewater from the second washing chamber. It is connected to the water cup 26, forming a complete wastewater recycling and treatment system. After the washing process is completed, the wastewater in the second washing chamber flows into the water cup 26 through the second drain pipe 29a, awaiting further discharge or treatment. The second spray component 60, as another important washing component, is designed inside the second washing chamber and is connected to the second water inlet pipe 29b. Thus, when the second water inlet pipe 29b receives cleaning water, this water is sprayed out through the second spray component 60 at a certain speed and angle to rinse and wash the dishes in the second washing chamber. This design not only improves washing efficiency but also ensures uniform and thorough washing. It is understandable that the structure of the second spray component 60 can be the same as that of the first spray component 40, both being spray arm structures.

[0080] Reference Figure 5In some embodiments, the front side of the cabinet 10 has a first loading port 11a communicating with the upper washing chamber 11 and a second loading port 12a communicating with the lower washing chamber 12. The dishwasher 100 also includes a first door and a second door. The first door is movably connected to the cabinet 10 to close or open the first loading port 11a. The second door is movably connected to the cabinet 10 to close or open the second loading port 12a.

[0081] The first door is connected to the cabinet 10 via a rotating connection, allowing users to easily open or close it to independently access and operate the upper washing chamber 11. Similarly, the second door is also connected to the cabinet 10 via a rotating connection, allowing users to independently open or close it to access and operate the lower washing chamber 12. This design not only improves the flexibility and convenience of washing but also ensures the efficiency and effectiveness of the washing process. Users can choose to place tableware into either the upper washing chamber 11 or the lower washing chamber 12 for individual washing based on the type, quantity, and washing needs, thus avoiding mutual interference between different types of tableware. Furthermore, this design helps maintain the cleanliness and airtightness of the cabinet 10. When a washing chamber is not needed, users can simply close the corresponding door to prevent dust and dirt from entering. Simultaneously, the tight closure of the doors ensures that water vapor and noise during the washing process do not leak into the external environment, providing users with a quieter and cleaner washing environment. Furthermore, both the first and second doors are equipped with viewing windows, allowing users to clearly observe the washing process within the upper washing chamber 11 and lower washing chamber 12 without opening the doors. Users can intuitively observe and assess the water flow, the arrangement of dishes, and the cleaning effect after washing. This design not only improves the transparency and controllability of the washing process but also eliminates the need for users to frequently open the doors to check on the washing, thus reducing energy loss and noise interference. Simultaneously, the viewing windows allow users to confidently leave the washing area to engage in other activities without worrying about any issues that may arise during the washing process.

[0082] In summary, these additional components and extended functions of a dishwasher together constitute an efficient and reliable washing system, providing users with superior washing results and a better user experience. Through careful design and optimization, these components work together to ensure stable and efficient operation of the dishwasher during the washing process.
