[0027] This invention proposes a dishwasher.

[0028] In the embodiments of the invention, reference is made to... Figures 1 to 17 The dishwasher 10 includes a body 100, a door assembly 300, and a partition assembly 200. The body 100 has an inner cavity 110 and an opening 120 communicating with the inner cavity 110. The door assembly 300 is movably disposed on the body 100 and is used to open or close the opening 120. The partition assembly 200 is installed in the inner cavity 110. The partition assembly 200 and the door assembly 300 cooperate with the body 100 to divide the inner cavity 110 into multiple independent sub-chambers.

[0029] The main body 100 is the core structure of the dishwasher 10, providing support and protection for the other components of the dishwasher 10. An inner cavity 110 is formed within the main body 100, which is the space inside the dishwasher 10 used for loading and washing dishes. Its size and shape determine the number and types of dishes the dishwasher 10 can hold. An opening 120 communicating with the inner cavity 110 is provided on one side of the main body 100, allowing users to easily place dishes and cookware into the inner cavity 110 for washing.

[0030] The door assembly 300 is movably mounted on the body 100 and movably covers the opening 120 for controlling the opening or closing of the opening 120. The door assembly 300 can be connected to the body 100 in a rotating, sliding, or detachable manner, and can be configured according to specific actual needs, without special limitations here.

[0031] The divider assembly 200 is a key feature of the dishwasher 10. By fixing or movably setting the divider assembly 200 in the inner cavity 110, and in conjunction with the door assembly 300, the inner cavity 110 can be divided into multiple relatively sealed sub-chambers. It should be noted that each sub-chamber is equipped with a spray system 500 and a water system 400 for individual washing. Users can select different sub-chambers to complete the washing process according to their needs.

[0032] This application provides a partition component 200 in the inner cavity 110 of the body 100. The partition component 200, the door panel component, and the body 100 together completely divide the inner cavity 110 into multiple relatively independent and sealed washing sub-chambers. Users can choose to use one sub-chamber individually or use multiple sub-chambers simultaneously for washing according to the amount of tableware, thus meeting different washing needs. At the same time, since each sub-chamber is relatively sealed, the mutual influence between sub-chambers can be reduced.

[0033] Reference Figures 1 to 11 According to one embodiment of the present invention, the door assembly 300 includes a plurality of door panels, and the partition assembly 200 cooperates with the body 100 to divide the opening 120 into a plurality of sub-openings. The plurality of sub-openings are respectively connected to different sub-cavities, and the plurality of door panels are respectively used to control the opening or closing of the plurality of sub-openings.

[0034] It is understood that the partition component 200 extends from the opening 120 toward the cavity wall opposite the opening 120 in the inner cavity 110, thereby dividing the inner cavity 110 into multiple sub-chambers. The opening 120 is also correspondingly divided by the partition component 200 into multiple sub-openings 120 communicating with the sub-chambers. In order to facilitate the individual opening or closing of each sub-chamber, the door assembly 300 in this embodiment includes multiple door panels corresponding to the sub-openings 120. These door panels are used to individually control the opening or closing of each corresponding sub-opening 120 to ensure the independence and sealing of each sub-chamber. When the user uses one of the multiple sub-chambers individually, he / she only needs to open the corresponding door panel to complete the user's target washing, thereby improving the user's convenience.

[0035] Reference Figures 12 to 17 In one embodiment, the door assembly 300 may also include a door panel, which controls the opening or closing of multiple sub-chambers and can be configured according to user needs.

[0036] Reference Figures 4 to 10According to one embodiment of the present invention, the partition assembly 200 includes a horizontal partition disposed along the horizontal direction of the inner cavity 110 to divide the inner cavity 110 into an upper sub-chamber 111 and a lower sub-chamber 112. That is, multiple sub-chambers are arranged along the height direction, which makes it convenient for users to select the upper sub-chamber 111 when using the dishwasher 10 frequently, reducing the number of times users bend over and improving user satisfaction.

[0037] In one embodiment, the partition assembly 200 may also include a vertical partition that divides the inner cavity 110 into a left sub-chamber 113 and a right sub-chamber 114. Of course, the partition assembly 200 may also include both horizontal and vertical partitions, or multiple horizontal or vertical partitions, to divide the inner cavity 110 into multiple horizontally or vertically arranged sub-chambers as needed, without any particular limitation.

[0038] Reference Figures 1 to 10 According to one embodiment of the present invention, the door assembly 300 includes an upper door panel 310 and a lower door panel 320. The upper door panel 310 is disposed corresponding to the upper sub-cavity 111 and is adapted to independently control the opening and closing of the upper sub-cavity 111. The lower door panel 320 is disposed corresponding to the lower sub-cavity 112 and is adapted to independently control the opening and closing of the lower sub-cavity 112.

[0039] Understandably, the upper door panel 310 can independently control the opening and closing of the upper sub-chamber 111. When only the upper sub-chamber 111 needs to be used for washing, only the upper door panel 310 can be opened, while the lower sub-chamber 112 remains closed, thereby maintaining the environmental stability or safety of the lower sub-chamber 112. Similarly, when only the lower sub-chamber 112 needs to be used for washing, only the lower door panel 320 can be opened, while the upper sub-chamber 111 remains closed, thereby maintaining the environmental stability or safety of the upper sub-chamber 111.

[0040] Reference Figure 11 In one embodiment, the inner cavity 110 is divided into a left sub-cavity 113 and a right sub-cavity 114, and the door assembly 300 includes a left door panel 340 and a right door panel 350. The left door panel 340 and the right door panel 350 can be set in the form of parallel doors or center doors. No special limitation is made here, and they can be set according to specific needs.

[0041] Reference Figures 3 to 5 According to one embodiment of the present invention, the door assembly 300 further includes an opening and closing frame 330, which is movably installed at the opening 120. The upper door panel 310 and the lower door panel 320 are connected to the opening and closing frame 330 to control the opening and closing of the upper sub-cavity 111 and the lower sub-cavity 112 respectively. The opening and closing frame 330 is suitable for controlling the opening and closing of the opening 120.

[0042] Understandably, the opening / closing frame 330 is movably mounted at the opening 120 of the body 100, allowing the frame to rotate or move relative to the body 100, thereby controlling the opening and closing state of the opening 120. This makes the opening / closing frame 330 a key component connecting the door panel and the body 100. Both the upper door panel 310 and the lower door panel 320 are connected to the opening / closing frame 330. The door panels move with the opening / closing frame 330, thus controlling the opening and closing states of the upper sub-chamber 111 and the lower sub-chamber 112. The opening / closing frame 330 not only provides a support and connection platform for the door panels but also directly participates in the opening and closing control of the opening 120. By controlling the movement of the opening / closing frame 330, the entire opening 120 can be opened and closed, simultaneously causing the upper door panel 310 and the lower door panel 320 to perform corresponding actions.

[0043] When it is necessary to open both the upper sub-chamber 111 and the lower sub-chamber 112 simultaneously, the opening frame 330 can be moved to one side to open the opening 120. At this time, the upper door panel 310 and the lower door panel 320 rotate or move together with the opening frame 330 to expose the corresponding sub-chambers. When it is necessary to close all sub-chambers, the opening frame 330 can be pushed back to its original position to close the opening 120. During this process, the upper door panel 310 and the lower door panel 320 will also close as the opening frame 330 moves, resealing the upper sub-chamber 111 and the lower sub-chamber 112. The upper and lower door panels can still be individually controlled to open and close their corresponding upper and lower sealed chambers, thus reducing the number of steps required to open the entire door assembly 300 and improving operational efficiency.

[0044] Reference Figures 3 to 5 According to one embodiment of the present invention, the door assembly 300 further includes an opening and closing frame 330, which is movably installed at the opening 120, the upper door panel 310 is movably installed on the opening and closing frame 330, and the lower door panel 320 is fixedly connected to the opening and closing frame 330.

[0045] It is understood that in this embodiment, the opening and closing frame 330 is designed to be movable relative to the body 100, such as by means of a slide rail, hinge, etc., thereby allowing it to move within a certain range to control the opening and closing of the opening 120.

[0046] The hinge frame 330 not only provides a mounting base for the upper door panel 310 and the lower door panel 320, but also ensures their relative positional relationship. It connects the upper door panel 310 and the lower door panel 320 together and allows the upper door panel 310 to move on it.

[0047] The upper door panel 310 is movably mounted relative to the opening and closing frame 330 and can be opened or closed independently to control the opening and closing state of the upper sub-chamber 111. The upper door panel 310 can be implemented via a slide rail, hinge, or other mechanical device. Because the upper door panel 310 is movably mounted, it can be opened or closed independently when the upper sealing chamber is frequently used by the user, without affecting the state of the lower door panel 320 or the entire opening and closing frame 330. This provides greater flexibility and control precision.

[0048] Unlike the upper door panel 310, the lower door panel 320 is fixedly connected to the opening and closing frame 330. The lower door panel 320 moves with the opening and closing frame 330 and cannot be opened or closed independently. When the opening and closing frame 330 opens or closes, the lower door panel 320 also opens or closes accordingly to control the opening and closing state of the lower sub-chamber 112. This improves the overall opening and closing efficiency of the door assembly 300.

[0049] Reference Figures 20 to 22 According to one embodiment of the present invention, the dishwasher 10 includes at least one water system 400 and multiple spray systems 500, the multiple spray systems 500 being arranged one-to-one with multiple sub-chambers, and the water system 400 being connected to the spray systems 500.

[0050] Understandably, the water system 400 is one of the core components of the dishwasher 10, providing the necessary water flow and pressure for cleaning, as well as handling wastewater discharge. This system may include components such as a water pump, water tank, filter, and heater to ensure that the cleanliness, temperature, and flow rate of the water meet the cleaning requirements.

[0051] The water system 400 is connected to the spray system 500, and the water system 400 can deliver clean water to each spray system 500 through pipes or hoses. This ensures that water is accurately distributed to the sub-chambers that need cleaning.

[0052] The dishwasher 10 is equipped with multiple spray systems 500, each corresponding to a specific sub-chamber. Each spray system 500 is designed for a particular sub-chamber to ensure complete coverage and effective cleaning of the dishes within that area. The spray systems 500 use high-pressure water jets to spray detergent and water mist, rinsing and cleaning the dishes. The spray systems 500 may include different types of nozzles, such as rotating spray arms or fixed nozzles, to provide diverse cleaning modes.

[0053] Multiple spray systems 500 correspond one-to-one with multiple sub-chambers, and each spray system 500 can be controlled independently to meet more refined cleaning needs.

[0054] The sub-chambers are the areas inside the dishwasher 10 used to place dishes. They are designed to be independent and well-sealed to prevent water from splashing out or cross-contamination during the washing process.

[0055] During the cleaning process of the dishwasher 10, the water system 400 first provides cleaning water and detergent to the spray system 500; then, the spray system 500 cleans the dishes in the corresponding sub-chambers with high-pressure water jets; finally, the cleaned water is discharged from the dishwasher 10 through the drain mechanism 410.

[0056] Because each sub-chamber has its own independent spray system 500 for cleaning, customized cleaning solutions can be provided for different types of tableware or different cleaning needs. At the same time, the independence of the sub-chambers also avoids cross-contamination problems during the cleaning process.

[0057] Reference Figures 20 to 22 According to one embodiment of the present invention, the water system 400 includes a drainage mechanism 410, which includes an upper drainage component and a lower drainage component. The upper drainage component is integrated on the partition component 200, and the lower drainage component is integrated at the bottom of the inner cavity 110.

[0058] Understandably, the top drain assembly is designed to drain wastewater accumulated in the upper sub-chamber after the washing process. The top drain assembly is integrated into the partition assembly 200, which is located at the bottom of the upper sub-chamber 111. Therefore, the position of the top drain assembly allows it to directly handle wastewater from the upper sub-chamber. Integrating the top drain assembly into the partition assembly 200 reduces the volume occupied by the top drain assembly when it is installed separately in the dishwasher 10, improving the space utilization of the inner cavity 110. This also helps to reduce the flow path of wastewater inside the dishwasher 10, lowering the risk of cross-contamination and improving drainage efficiency.

[0059] The drain assembly is integrated into the bottom of the dishwasher 10 cavity 110. The drain assembly is responsible for collecting and draining wastewater from the lower sub-chamber 112.

[0060] Thus, the drainage efficiency and effectiveness of the dishwasher 10 are improved through the zoned drainage design. By treating the wastewater from the upper sub-chamber 111 and the lower sub-chamber 112 separately, the residence time of wastewater inside the dishwasher 10 can be reduced, the risk of cross-contamination can be lowered, and the speed of the entire drainage process can be accelerated.

[0061] Reference Figures 20 to 22 According to one embodiment of the present invention, the partition component 200 is inclined upward from the side of the inner cavity 110 opposite to the opening 120 toward the opening 120, and the partition component 200 is provided with an upper drain outlet 210 on the side away from the opening 120.

[0062] Understandably, the tilt of the divider assembly 200 means that its upper surface is not perfectly perpendicular to the horizontal plane, but rather has a certain slope. This causes the divider assembly 200 to gradually rise in the direction towards the opening 120, forming a slope. This helps guide wastewater along the slope to the upper drain outlet 210, making it easier to drain from the dishwasher 10. Secondly, the tilted divider assembly 200 can reduce the accumulation of wastewater in the upper chamber 111, reducing the risk of cross-contamination. In addition, the tilted design may also help reduce cleaning dead spots inside the dishwasher 10, making cleaning easier.

[0063] The upper drain outlet 210 is located on the side of the separator assembly 200 away from the opening 120, i.e., at a lower position of the separator assembly 200. This allows wastewater to naturally collect at the upper drain outlet 210 as it flows along the slope of the separator assembly 200.

[0064] The main function of the upper drain outlet 210 is to drain the wastewater accumulated above the separator assembly 200 from the dishwasher 10. Due to the inclined design of the separator assembly 200, the wastewater can flow smoothly and be discharged through the upper drain outlet 210, thereby improving drainage efficiency.

[0065] Reference Figures 20 to 22 According to one embodiment of the present invention, the partition assembly 200 includes a first partition portion 220 and a second partition portion 230, with the adjacent sides of the first partition portion 220 and the second partition portion 230 inclined downwards. It is understood that by forming a V-shaped structure with the adjacent sides of the first partition portion 220 and the second partition portion 230 inclined downwards, wastewater will form a confluence area at its low-lying position when flowing through the upper end face of the partition assembly 200. Simultaneously, since the partition assembly 200 is inclined towards the upper drain outlet 210, the wastewater can be discharged from the upper chamber 111 more quickly under the guidance of the secondary inclination of the upper end face of the partition assembly 200, thus improving wastewater discharge efficiency.

[0066] In other embodiments, the cross-section of the separator 200 parallel to the opening 120 may be W-shaped or arc-shaped to form a water collection area on the upper surface of the separator 200.

[0067] Reference Figures 20 to 22 According to one embodiment of the present invention, a water collection trough 240 is formed between the first partition portion 220 and the second partition portion 230. The water collection trough 240 extends along the depth direction of the opening 120 and is connected to the upper drain outlet 210. A filter element 250 is provided at the opening of the water collection trough 240.

[0068] Understandably, the water collection tank 240 is located between the first partition section 220 and the second partition section 230, and its shape and size depend on the specific design of the dishwasher 10. Typically, the water collection tank 240 is provided to extend along the depth direction of the opening 120 in order to collect wastewater and residue from the upper area.

[0069] The water collection tank 240 is used to collect and temporarily store wastewater, keeping the interior of the dishwasher 10 clean and hygienic. The water collection tank 240 is connected to the upper drain outlet 210, allowing wastewater collected in the water collection tank 240 to be smoothly discharged from the dishwasher 10 through the upper drain outlet 210. This ensures that wastewater is discharged promptly and effectively, preventing accumulation and stagnation inside the dishwasher 10. Due to the presence of the water collection tank 240, wastewater is first collected and temporarily stored in the water collection tank 240 during the discharge process, and then discharged through the upper drain outlet 210. This helps reduce splashing and overflow during the discharge process, improving drainage efficiency.

[0070] The filter element 250 is installed at the opening of the water collection tank 240. Located between the water collection tank 240 and the upper area, it is used to prevent large pieces of food residue, grease, and other impurities from entering the water collection tank 240. Through the filtration effect of the filter element 250, it is ensured that only wastewater enters the water collection tank 240 and the upper drain outlet 210, thereby protecting the smooth operation of the drainage system.

[0071] Reference Figures 20 to 22 According to one embodiment of the present invention, the filter element 250 is provided with a handle at one end of the opening 120. It is understood that the handle is located at or near the edge of the filter element 250 at one end of the opening 120, allowing the user to easily access and operate it. The handle is typically designed with an easy-to-grip shape, such as a groove, a protrusion, or a handle. When the filter element 250 accumulates excessive impurities and affects drainage, the user can easily remove the filter element 250 for cleaning using the handle. After cleaning, the filter element 250 can be returned to its original position using the handle.

[0072] In some embodiments, the dishwasher 10 further includes a slag discharge system, with a slag discharge port at the bottom of the sub-chamber, and the slag discharge system is connected to the sub-chamber through the slag discharge port.

[0073] Understandably, the waste removal system is designed to automatically or manually remove food residue accumulated at the bottom of the sub-chamber from the dishwasher 10 after the washing process is complete. This prevents residue from accumulating inside the dishwasher 10, which could lead to bacterial growth, odors, and negatively impact subsequent cleaning performance.

[0074] According to one embodiment of the present invention, the water system 400 further includes a water inlet mechanism 420, which includes an upper water inlet component and a lower water inlet component. The upper water inlet component and the lower water inlet component are respectively connected to the spray system 500 in the upper sub-chamber 111 or the lower sub-chamber 112.

[0075] Understandably, the upper water inlet assembly is connected to the spray system 500 within the upper sub-chamber 111 of the dishwasher 10. When the upper dishes need to be washed, the upper water inlet assembly supplies cleaning water to the spray system 500. The main function of the upper water inlet assembly is to provide a stable and appropriate amount of cleaning water to the spray system 500 within the upper sub-chamber 111. This cleaning water is sprayed onto the dishes through the spray system 500 to remove stains and food residue. The lower water inlet assembly is connected to the spray system 500 within the lower sub-chamber 112 of the dishwasher 10. Similar to the upper water inlet assembly, the lower water inlet assembly is responsible for supplying cleaning water to the dishes in the lower sub-chamber 112.

[0076] During the washing process of the dishwasher 10, the upper water inlet assembly and the lower water inlet assembly work together. According to the control program of the dishwasher 10 and the user's settings, they respectively provide an appropriate amount of cleaning water to the spray system 500 in the upper sub-chamber 111 and the lower sub-chamber 112 to ensure that all the dishes inside the dishwasher 10 are thoroughly cleaned.

[0077] According to one embodiment of the present invention, the dishwasher 10 further includes at least one drying system, the drying system including a drying module and an air duct, and an upper drying port and a lower drying port communicating with the air duct are provided on the inner walls of the upper sub-chamber 111 and the lower sub-chamber 112, and the drying module dries the upper sub-chamber 111 and the lower sub-chamber 112 through the upper drying port and the lower drying port.

[0078] Understandably, the drying system is an additional feature of the dishwasher 10, designed to dry dishes and other items after washing to remove residual moisture and prevent bacterial growth.

[0079] In this embodiment of the invention, the drying system includes a drying module and an air duct. The drying module is the main part that generates hot air, while the air duct is used to deliver the hot air to various corners within the washing chamber 110.

[0080] Specifically, upper drying inlets and lower drying inlets, which are connected to air ducts, are respectively opened on the inner walls of the upper sub-chamber 111 and the lower sub-chamber 112. The function of these two drying inlets is to evenly introduce the hot air or hot air generated by the drying module into the two sub-chambers to dry tableware and other items.

[0081] After the dishwasher 10 completes the washing process, the drying module starts working, generating hot air. This hot air enters the upper sub-chamber 111 and the lower sub-chamber 112 through the air ducts, passing through the upper drying port and the lower drying port respectively, to dry the tableware and other items in the chamber.

[0082] By incorporating a drying system, dishes and other items can be automatically dried after washing, avoiding the hassle of manual wiping and the possibility of secondary contamination. The design of the air duct and drying vent ensures that hot air is evenly delivered to every corner of the washing chamber, improving drying efficiency and quality.

[0083] In some embodiments, the drying module can be configured as a pair of multiple sub-chambers or a pair of one sub-chambers, that is, one drying module corresponds to multiple sub-chambers or one drying module corresponds to one sub-chamber, without any special limitation.

[0084] Reference Figures 18 to 19 In one embodiment, the dishwasher 10 includes a body 100, a partition assembly 200, and a drive assembly. The body 100 has an inner cavity 110. The partition assembly 200 is disposed in the inner cavity 110 to divide the inner cavity 110 into at least two independent sub-chambers. The drive assembly is connected to the partition assembly 200 and is adapted to drive the partition assembly 200 to move along a first direction of the inner cavity 110 to dynamically adjust the volume ratio of two adjacent sub-chambers.

[0085] In this embodiment, the drive component is closely connected to the partition component 200, and its function is to drive the partition component 200 to move along the inner cavity 110 in a first direction. This first direction is usually preset and can be adjusted according to the specific design of the dishwasher 10. Through precise control of the drive component, the user can easily adjust the volume ratio of two adjacent sub-chambers according to the amount or size of the tableware to adapt to different cleaning needs. By dynamically adjusting the volume ratio of two adjacent sub-chambers, the dishwasher 10 can more flexibly handle different quantities and types of tableware, which helps to optimize the water flow distribution and spray angle during the cleaning process, thereby improving cleaning efficiency and quality. When the number of tableware is small, the user can reduce the volume of the corresponding sub-chamber to reduce water and energy consumption during the cleaning process. This energy-saving design meets the modern family's pursuit of environmental protection and energy conservation. The function of dynamically adjusting the volume ratio makes the dishwasher 10 more intelligent and user-friendly. Users can freely adjust the size and number of sub-chambers according to their actual needs and enjoy a more convenient and efficient cleaning experience.

[0086] The drive components may take various forms, such as motors, gear transmission mechanisms, and lead screw transmission mechanisms. These components work together under the command of the control system to ensure that the separator assembly 200 can move smoothly and accurately.

[0087] It is understood that the first direction can be either the horizontal or vertical direction of the inner cavity 110, and no special limitation is made here. This embodiment mainly uses the vertical direction as an example for illustration, and other embodiments can be implemented with reference to this embodiment.

[0088] In some embodiments, the dishwasher 10 further includes a sealing assembly disposed between the partition assembly 200 and the cavity wall of the inner cavity 110.

[0089] Understandably, the sealing assembly is positioned between the partition assembly 200 and the cavity wall of the inner cavity 110 to fill the tiny gap between them, preventing water, steam, detergent, or other cleaning media from leaking into adjacent sub-cavities or the outside of the dishwasher 10 during the cleaning process. This ensures an independent cleaning environment inside each sub-cavity and protects the internal components of the dishwasher 10 from damage.

[0090] Optionally, the sealing component may include a sealing strip, sealing ring, or sealing gasket, etc. The specific form can be selected according to the design of the dishwasher 10 and the shape of the partition component 200, and is not specifically limited here.

[0091] In some embodiments, the cavity wall of the inner cavity 110 is flush with the outer peripheral wall of the partition assembly 200.

[0092] It is understandable that setting the cavity wall of the inner cavity 110 and the outer peripheral wall of the partition component 200 to be flush with each other can make it easier for the drive component to move the partition component 200 along the first direction of the inner cavity 110, while making the sealing component fit better between the two to maintain the sealing performance of the two adjacent sub-cavities.

[0093] In one embodiment, at least two sub-chambers include an upper sub-chamber 111 and a lower sub-chamber 112. The dishwasher 10 includes an upper spray system and a lower spray system. The upper spray system is correspondingly disposed in the upper sub-chamber 111, and the lower spray system is correspondingly disposed in the lower sub-chamber 112. The upper spray system and the lower spray system are respectively connected to the water system 400.

[0094] Understandably, the upper sub-chamber 111 is located in the upper part of the inner cavity 110 of the dishwasher 10, and the upper spray system is correspondingly installed in the upper sub-chamber 111, spraying water and detergent onto the dishes in this area through multiple spray arms or nozzles. The lower sub-chamber 112 is located in the lower part of the inner cavity 110 of the dishwasher 10, and the lower spray system is correspondingly installed in the lower sub-chamber 112, performing a similar cleaning task to the upper spray system. Thus, by separately configuring the upper and lower spray systems for the upper and lower sub-chambers 111 and 112, both chambers can be used independently. Users can choose to use one or both for washing according to their needs, improving the applicability of the dishwasher 10 and user satisfaction.

[0095] In some embodiments, the upper spray system is disposed on the partition component 200 and can move with the partition component 200.

[0096] Understandably, the upper spray system is directly mounted on the partition assembly 200, so that when the partition assembly 200 moves within the inner cavity 110 to adjust the volume ratio of the upper sub-chamber 111 and the lower sub-chamber 112, the upper spray system also moves accordingly. This ensures that the spray system 500 can effectively clean the tableware in the upper sub-chamber 111.

[0097] Because the upper spray system can move with the partition component 200, it can dynamically adjust the cleaning area according to the position of the partition component 200. This ensures that the upper spray system can thoroughly and evenly clean the tableware in the upper chamber 111 regardless of how the partition component 200 moves.

[0098] Because the upper spray system is tightly integrated with the partition component 200, it can more precisely control the spray direction and spray intensity, thereby ensuring that the water flow and detergent can directly act on the surface of the tableware and improve the cleaning effect.

[0099] Of course, in other embodiments, the upper spray assembly may also be fixedly installed on the top of the upper sub-chamber 111, or the spray system 500 may be installed on the top or bottom of the upper sub-chamber 111, without any special limitation.

[0100] In some embodiments, the water system 400 includes a water inlet mechanism 420 and a drainage mechanism 410, which are respectively connected to the upper sub-chamber 111 and the lower sub-chamber 112.

[0101] Understandably, the water inlet mechanism 420 is designed to provide the necessary water flow and cleaning agent for cleaning the upper sub-chamber 111 and the lower sub-chamber 112. The water inlet mechanism 420 is connected to the upper sub-chamber 111 and the lower sub-chamber 112 respectively via specific pipes or connectors. During the cleaning process, the water inlet mechanism 420 supplies appropriate amounts of water and cleaning agent to the corresponding sub-chambers according to a preset cleaning program.

[0102] The drainage mechanism 410 is designed to drain wastewater from the upper sub-chamber 111 and lower sub-chamber 112 of the dishwasher 10 after washing. It typically includes components such as a drain pump, drain pipes, and drain valves, enabling rapid and efficient drainage of wastewater from the dishwasher 10. The drainage mechanism 410 is also connected to the upper sub-chamber 111 and lower sub-chamber 112 via specific pipes or connectors. During drainage, the drainage mechanism 410 opens the corresponding drain valves and activates the drain pumps to extract wastewater from the sub-chambers and discharge it from the dishwasher 10.

[0103] By connecting the water inlet mechanism 420 and the drain mechanism 410 to the upper sub-chamber 111 and the lower sub-chamber 112 respectively, the dishwasher 10 can achieve independent cleaning of the two sub-chambers. This enhances the flexibility and practicality of the dishwasher 10.

[0104] In some embodiments, the dishwasher 10 further includes a heating system connected to the water system 400, the heating system being adapted to heat the washing water in the water system 400.

[0105] Understandably, the heating system is typically integrated into the water system 400, connected to the water inlet mechanism 420 and the washing chamber via pipes and valves. During the washing process, when heating of the washing water is required, the heating system activates and heats the cold water in the water flow, then delivers the heated washing water to the washing chamber for cleaning. As the washing water temperature increases, the activity of the detergent also increases, making it easier to penetrate stains and break them down. Therefore, the heating system significantly improves the cleaning power of the dishwasher 10, resulting in cleaner dishes. High-temperature washing water not only helps remove stains but also sterilizes and disinfects the dishes. This is crucial for maintaining the hygiene of the dishes and preventing bacterial growth. At higher temperatures, stains and grease are more easily washed away by the water flow, thus reducing washing time and energy consumption.

[0106] In one embodiment, the dishwasher 10 includes a body 100, a door assembly 300, and a divider assembly.

[0107] 200, the body 100 has an inner cavity 110 and an opening 120 communicating with the inner cavity 110; the door assembly 300 is used to flexibly open or close the opening 120; the partition assembly

[0108] 200 is suitable for dividing the inner cavity 110 into an independent upper sub-chamber 111 and a lower sub-chamber 112; wherein, the dishwasher 10 includes at least one operating mode, in which the upper sub-chamber 111 is washed alone and the lower sub-chamber 112 is not activated.

[0109] In this embodiment, a partition assembly divides the inner cavity 110 of the machine body 100 into two independent upper sub-chambers 111 and lower sub-chambers 112. Users can select the dishwasher 10's operating mode according to their needs. In the first operating mode, only the upper sub-chamber 111 performs a separate washing program, while the lower sub-chamber 112 remains stationary, thus enabling the independent use of the upper chamber 111. In scenarios with infrequent but less frequent use, this improves washing efficiency and energy savings while reducing the number of times users bend over. Furthermore, it allows for simultaneous washing of dishes in both chambers. Users can choose the appropriate washing method based on their actual needs, enhancing the flexibility and convenience of using the dishwasher 10.

[0110] In some embodiments, the dishwasher 10 further includes a water system 400, an upper spray system 500, and a lower spray system 500, wherein the water system 400 is individually connected to the upper spray system 500 and the lower spray system 500, respectively.

[0111] Understandably, the dishwasher 10 includes a water system 400, which is separately connected to the upper sub-chamber 111 and the lower sub-chamber 112. The water system 400 is responsible for supplying water, draining water, and providing detergent to each sub-chamber of the dishwasher 10. The water system 400 may include a complex network of pumps, pipes, valves, etc., used to control the direction and flow rate of water.

[0112] The upper spray system 500 is set up corresponding to the upper sub-chamber 111 and is used to complete the spray washing program of the upper sub-chamber 111.

[0113] The lower spray system 500 is set in the lower sub-chamber 112 to complete the spray washing program of the lower sub-chamber 112.

[0114] The water system 400 is independently connected to the upper spray system 500 and the lower spray system 500, so that water can be supplied to the upper spray system 500 and the lower spray system 500 independently through the water system 400. In this way, by independently controlling the upper spray system 500 and the lower spray system 500, the upper sub-chamber 111 or the lower sub-chamber 112 can be used independently. At the same time, one water system 400 corresponds to multiple sub-chambers, which can simplify the setting of the water system 400 and reduce the overall size of the dishwasher 10.

[0115] In some embodiments, the dishwasher 10 further includes a second operating mode in which the upper sub-chamber 111 and the lower sub-chamber 112 are washed separately.

[0116] In the second working mode, users can perform separate washing according to different tableware or different levels of oil stains, and customize different washing times or conditions; and because the upper sub-chamber 111 and the lower sub-chamber 112 are relatively sealed, the washing process is completely independent and there will be no cross-contamination.

[0117] In some embodiments, the water system 400 includes a washing pump and a water distribution valve, the washing pump being connected to an upper spray system and a lower spray system via the water distribution valve.

[0118] Understandably, the washing pump provides the power source for the entire water system 400, responsible for pressurizing and discharging the stored washing water. The water distribution valve is a crucial control component, located between the washing pump and the spray system 500, responsible for precisely distributing the washing water to the upper and lower spray systems. The water distribution valve typically contains multiple channels and valve structures; by controlling the opening and closing of the valve, precise control of the water flow direction and flow rate can be achieved. When the user selects different washing modes, the dishwasher 10's control system adjusts the state of the water distribution valve accordingly to meet the water supply needs of different spray systems 500.

[0119] The upper and lower spray systems are responsible for cleaning the tableware in the upper sub-chamber 111 and lower sub-chamber 112, respectively. They use spray arms to propel high-pressure water and detergent onto the tableware surface, utilizing the impact of the water flow and the chemical action of the detergent to remove stains and grease. Since the upper and lower spray systems correspond to different chambers, they can operate independently or simultaneously to meet different cleaning needs. Through the coordinated operation of the washing pump and water distribution valve, the water system 400 can supply water to the upper and lower spray systems independently or simultaneously, thus satisfying different cleaning requirements.

[0120] In one embodiment, the dishwasher 10 includes a body 100, a partition assembly 200, a water system 400, and a distributor. The body 100 has an inner cavity 110. The partition assembly 200 is installed in the inner cavity 110 to divide the inner cavity 110 into a relatively independent upper sub-chamber 111 and a lower sub-chamber 112. The drainage mechanism 410 is adapted to supply and drain water to the upper sub-chamber 111 and the lower sub-chamber 112. The distributor is connected to the water system 400, and the water system 400 communicates with the upper sub-chamber 111 and the lower sub-chamber 112 through the distributor to individually control the water supply and drainage of the upper sub-chamber 111 and the lower sub-chamber 112.

[0121] In this embodiment, the inner cavity 110 of the body 100 is divided into two independent sub-chambers by a partition assembly. The water system 400 is connected to each sub-chamber individually via a distributor, enabling independent water inlet and outlet for each sub-chamber. Users can flexibly choose to clean only the upper sub-chamber 111, the lower sub-chamber 112, or both chambers simultaneously, depending on the type of tableware, the degree of grease, and cleaning needs. This not only improves cleaning efficiency but also meets users' personalized tableware cleaning needs. Furthermore, because the cleaning processes of the two sub-chambers are independent, the risk of cross-contamination is reduced, ensuring the hygiene and safety of the tableware.

[0122] In some embodiments, the water system 400 includes a water inlet mechanism 420 and a drainage mechanism 410, which are respectively connected to the upper sub-chamber 111 and the lower sub-chamber 112, and a distributor is respectively connected to the water inlet mechanism 420 and the drainage mechanism 410.

[0123] Understandably, the water inlet mechanism 420 is designed to provide the water source required for cleaning the dishwasher 10. It typically includes components such as a water pump, filter, and heater, as well as a series of connecting pipes for delivering cleaning water to various parts of the dishwasher 10. In this embodiment, the water inlet mechanism 420 is not only directly connected to the upper sub-chamber 111 and the lower sub-chamber 112, but also precisely distributes the water flow through a distributor. This allows the water inlet mechanism 420 to provide the appropriate amount of cleaning water to the upper and lower sub-chambers simultaneously or separately as needed.

[0124] The drainage mechanism 410 is used to discharge wastewater generated during the washing process from the dishwasher 10. It typically includes a drain pump, drain pipes, and an anti-backflow device. In this embodiment, the drainage mechanism 410 is also connected to both the upper sub-chamber 111 and the lower sub-chamber 112, ensuring that wastewater from both chambers can be quickly and effectively discharged after washing. Since the distributor is connected to both the water inlet mechanism 420 and the drainage mechanism 410, the distributor can assist the drainage mechanism 410 in achieving more precise drainage control, such as indirectly affecting the drainage speed and efficiency by adjusting the water inlet flow rate.

[0125] The distributor can precisely adjust the water flow and pressure entering the upper sub-chamber 111 and the lower sub-chamber 112 according to the preset cleaning program or user instructions. At the same time, it can also assist in adjusting the drainage speed and flow direction during the drainage stage to achieve a more efficient and energy-saving cleaning process.

[0126] In some embodiments, the water inlet mechanism 420 and the drainage mechanism 410 connecting the upper sub-chamber 111 are attached to the wall of the inner cavity 110.

[0127] Understandably, attaching the water inlet mechanism 420 and the drain mechanism 410 to the wall of the inner cavity 110 can maximize the use of space inside the dishwasher 10. The internal space of the dishwasher 10 is limited, while the placement of dishes, the movement of the spray arms, and the dispensing of detergent all require space. Therefore, attaching the water system components 400 (such as the water inlet mechanism 420 and the drain mechanism 410) to the wall allows for more space for dishwashing and spray arm movement, thereby improving cleaning efficiency and effectiveness.

[0128] In some embodiments, the dishwasher 10 further includes at least one sterilization system for sterilizing tableware in the upper chamber 111 or the lower chamber 112.

[0129] It is understood that in this embodiment, a disinfection system can be set up to disinfect the upper sub-chamber 111 and the lower sub-chamber 112, which can reduce the internal space occupied by multiple disinfection systems. Of course, in other embodiments, a separate disinfection system can be set up for each of the upper sub-chamber 111 and the lower sub-chamber 112.

[0130] Optionally, the disinfection system can be one or a combination of two or more of the following modes: high-temperature disinfection, ultraviolet disinfection, or ozone disinfection, to disinfect the sub-chamber.

[0131] In some embodiments, the water system 400 further includes a water circulation system connected between the sub-chamber and the spray system 500.

[0132] Understandably, the water circulation system can collect and filter the washing water sprayed by the spray system 500 in the sub-chamber during the washing or rinsing process, and then spray it again through the spray system 500 to spray the tableware in the sub-chamber, which can effectively save water resources.

[0133] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
