[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. Utility Model Content

[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.

[0042] 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.

[0043] 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.

[0044] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes a dishwasher 100. In the embodiments of this application, the dishwasher 100 includes a cabinet 10, a water system 20, a partition member 30, and a first spray member 40.

[0045] 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.

[0046] 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.

[0047] Reference Figure 2 and Figure 4 In some embodiments, the water system 20 further includes a first inlet pipe 22 and a first drain pipe 21, both of which are located within the lower washing chamber 12 and are attached to the lower surface of the partition member 30 and the wall of the lower washing chamber 12. The first inlet pipe 22 serves 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 member 40, providing the necessary water resources for the washing process. One end of the first drain pipe 21 is connected to the drain pump 28 of the water system 20, while the other end is connected to the drain outlet 31 of the upper washing chamber 11. The drain outlet 31 can be located either on the partition member 30 or on the wall of the upper washing chamber 11 within the cabinet 10.

[0048] 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 and lower washing chambers 11 and 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. It should be noted that this sealed connection can be implemented in various and flexible ways. On one hand, the partition member 30 can be directly attached to the cavity wall of the cabinet 10, ensuring tight contact through precise dimensional design and manufacturing processes to achieve a sealing effect. On the other hand, to further enhance the sealing performance, the partition member 30 can also be connected to the cavity wall of the cabinet 10 using sealant. The addition of sealant can not only effectively fill the tiny gaps between the partition component 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 component 30 will not loosen or fall off during long-term use.

[0049] Optionally, the upper washing chamber 11 and the lower washing chamber 12 have unequal volumes. This allows them to accommodate washing dishes of different sizes. In actual use, users can flexibly choose to wash either the upper washing chamber 11 or the lower washing chamber 12 according to the quantity and size of the dishes, or use both chambers simultaneously for layered washing, thus greatly improving the flexibility and efficiency of washing. This unequal volume design not only meets the diverse washing needs of users for different dishes, but also further enhances the practicality and convenience of the dishwasher 100.

[0050] 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.

[0051] In another embodiment, the cabinet 10 also 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 installation flexibility of 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.

[0052] The first spray component 40 is disposed on the upper surface of the partition component 30 and is connected to the internal water channel (not shown) to spray the upper washing chamber 11. This achieves all-round cleaning of the tableware using water flow, thereby greatly improving the washing effect and efficiency. With this structural configuration, the dishwasher 100 not only achieves thorough cleaning of the tableware, but also ensures the stability and reliability of the washing process.

[0053] 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 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. At the same time, when washing dishes in the upper and lower washing chambers simultaneously, different washing intensities and durations can be flexibly set according to the actual needs of each layer of dishes, such as the degree of oil stains and the type of dishes, thereby ensuring cleaning effect while significantly saving water resources and electricity consumption, shortening the washing cycle, and further improving the overall cleaning efficiency and energy utilization of the dishwasher 100.

[0054] In addition, the dishwasher 100 includes a first spray component 40 disposed on the upper surface of the partition component 30 and connected to the internal water passage. During the washing process, the first spray component 40 can spray water into the upper washing chamber 11 to spray and clean the dishes from all directions. This design not only improves the efficiency and effectiveness of the cleaning, but also allows the dishes in the upper washing chamber 11 to be cleaned more evenly and thoroughly.

[0055] Reference Figures 5 to 7 In some structural configurations, the first spray component 40 includes a spray cover 41, which is mounted on the upper surface of the partition component 30. The spray cover 41 has multiple spray holes 411 that are connected to the internal water channels. To further optimize washing performance, the first spray component 40 is designed to include the spray cover 41. The spray cover 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. Multiple spray holes 411 are carefully arranged on the spray cover 41. These holes 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 starts, cleaning water is delivered to the spray cover 41 through the internal water channels and sprayed out at high speed from the spray holes 411, creating a powerful water jet impact that deeply cleans 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.

[0056] 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.

[0057] Optionally, the nozzle 411 can be any one of a strip-shaped, round, elliptical, or square nozzle. This means that in practical applications, the shape of the nozzle 411 can be flexibly selected according to specific needs or design requirements. This design flexibility helps to meet the spray performance requirements in different scenarios, such as flow rate, spray angle, or spray range. Therefore, whether a uniformly distributed circular spray, a long strip spray trajectory, or other specific spray patterns are required, they can all be achieved by selecting the shape of the nozzle 411.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Optionally, the diameter of the spray hole 421 is larger than that of the spray hole 411. This difference in diameter design between the spray hole 421 on the spray arm and the spray hole 411 on the spray cover 41 is actually to better meet the diverse needs of the washing process. The larger diameter of the spray hole 421 allows for a greater flow rate and a wider spray range, which is significant for improving spray efficiency and enhancing cleaning effectiveness. Meanwhile, the spray hole 411 on the spray cover 41, with its fixed position and smaller diameter, enables precise cleaning of specific areas or hard-to-reach corners.

[0062] Furthermore, multiple spray nozzles 411 are located on the same side of the spray arm 42 and arranged from front to back along the cabinet 10. 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 front to back from each spray nozzle 411 along this side of the spray arm 42. 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 every area in 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.

[0063] Reference Figure 9Optionally, 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.

[0064] 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, bringing users a superior cleaning effect and user experience.

[0065] Reference Figure 7In some embodiments, the upper surface of the partition member 30 is recessed to form a mounting groove 33, and the spray cover plate 41 is embedded in the mounting groove 33, with spray holes 411 penetrating the surface of the spray cover plate 41 facing away from the mounting groove 33. The presence of the mounting groove 33 simplifies and improves the installation process of the partition member 30. Operators do not need to perform complex positioning or adjustments; they can simply place the spray cover plate 41 directly into the mounting groove 33 to complete the installation. This design not only reduces installation difficulty but also shortens installation time and improves overall production efficiency. Furthermore, the upper surface of the partition member 30 and the surface of the spray cover plate 41 facing away from the mounting groove 33 can be coplanar. This design detail means that when the spray cover plate 41 is accurately embedded in the mounting groove 33 of the partition member 30, its surface facing away from the mounting groove 33 will remain on the same plane as the upper surface of the partition member 30. This coplanar arrangement not only ensures the flatness and consistency of the washing chamber, but also effectively avoids gaps or unevenness that may occur during installation, thereby ensuring the sealing and cleanliness of the upper washing chamber 11.

[0066] More importantly, the coplanar arrangement also helps improve the performance of the spray system. Since there are no steps or gaps between the spray cover 41 and the partition member 30, the water flow remains smooth and uniform as it passes through the spray cover 41, resulting in a more efficient spraying effect. This design not only improves the cleanliness of every corner within the washing chamber but also ensures that stains on the surface of the tableware are thoroughly removed.

[0067] Reference Figure 6 Furthermore, the surface of the spray cover 41 facing away from the mounting groove 33 is inclined towards the center of the partition member 30. This inclined surface of the spray cover 41 means that the water flow passing through it will be guided towards the center of the partition member 30 by a guiding force. This design helps to achieve a more even distribution of water flow, ensuring that dishes in every corner of the washing chamber are thoroughly cleaned. At the same time, the inclined surface effectively reduces water accumulation and stagnation on the spray cover 41, thereby reducing the risk of dirt and bacterial growth.

[0068] 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.

[0069] 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 lower 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 lower 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 lower 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 lower 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.

[0070] Reference Figure 1 In 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.

[0071] 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.
