[0042] In the design of modern dishwashers, chamber division design is increasingly concerned, which aims to meet the diversified needs of different users for dish cleaning by dividing the washing space into multiple independent areas, such as cleaning different types of dishes at the same time, and improving cleaning efficiency.

[0043] In the structure of the dish washing machine with separate cavities, the filter assembly is a crucial component that mainly filters food residues and other impurities generated during the washing process to ensure the cleanliness of the washing water and thus improve the washing effect. However, the current design usually sets the filter assembly of the upper washing cavity at the rear side of the upper washing cavity. This position design brings many inconveniences, especially when the user cleans the residues. It is difficult to operate. Since the filter assembly is at the rear side of the upper washing cavity, the user needs to reach into the washing cavity or use a tool to access the filter assembly, which not only is inconvenient to operate, but also may cause the user to accidentally collide with other components inside the washing cavity during the cleaning process, causing damage. Moreover, the rear position makes it difficult to observe the blockage of the filter assembly. The user cannot intuitively understand the working status of the filter assembly, and thus it is difficult to clean in time, which affects the user experience and cleaning effect of the dish washing machine to some extent.

[0044] To this end, the embodiments of the present application provide a dish washing machine to solve the problem of inconvenient operation when cleaning residues of the filter assembly.

[0045] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 the structure diagram of the dish washing machine provided by the embodiments of the present application; Figure 2 the side view of the dish washing machine provided by the embodiments of the present application.

[0046] The dish washing machine of the embodiments of the present application comprises a shell, a base, an inner container 10, a door body 50, a partition 20, and a filter assembly 30.

[0047] The shell and the base of the dish washing machine constitute the basic framework of the entire dish washing machine. The shell wraps the inner container 10 and other internal components, which plays a role in protecting the internal structure and beautifying the appearance. The base is used to support the inner container 10 and the internal structure of the entire dish washing machine, ensuring that the dish washing machine remains stable during operation. The base is usually made of strong and durable materials, such as high-strength plastic or metal, to withstand the various weights and pressures generated by the inner container 10, utensils, and the washing process. The base can be provided with support feet with reinforcing ribs to further enhance stability. While the shell can be made of different materials according to different design requirements, such as metal shell for better durability and texture, and plastic shell for lighter weight and cost control.

[0048] The inner container 10 of the embodiment is a key component of the dishwasher, which constitutes a washing inner cavity 100 for accommodating tableware. The inner container 10 can be formed by a top plate, a bottom plate, left and right side plates, and a back plate, forming a relatively closed space to prevent water and detergent from leaking during washing, and to ensure that the washing work is carried out in a stable environment. For example, during the water spraying washing stage, the inner container 10 can withstand the internal water pressure to ensure that water does not seep out, thereby achieving efficient cleaning of tableware.

[0049] In one embodiment, a dish rack is installed in the washing inner cavity 100 for placing tableware. The dish rack is arranged in a movable manner, for example, being arranged in the washing inner cavity 100 in a push-pull manner. In this way, the user can flexibly adjust the position of the dish rack according to the type and quantity of tableware, so as to better adapt to the placement requirements of different tableware. For example, when a large number of dishes need to be cleaned, the dish rack can be pulled out, and the dishes can be arranged more conveniently on the dish rack, and then the dish rack can be pushed back into the washing inner cavity 100 for cleaning.

[0050] The door body 50 of the embodiment is movably connected to the opening of the inner container 10, and can be arranged in a rotating manner. The rotating connection manner allows the door body 50 to be easily opened and closed, and facilitates the user to take and place tableware. For example, the user only needs to pull or push the door body 50 slightly, and the door body 50 can be smoothly rotated around the rotating shaft to realize the opening and closing actions.

[0051] In one embodiment, a control panel for controlling the washing program is arranged on the door body 50. The control panel integrates various operation buttons and a display screen. The user can select different washing modes such as standard washing and quick washing through the operation buttons to adapt to the cleaning requirements of different types of tableware. The display screen displays the working state of the dishwasher in real time, such as the remaining washing time, the current washing mode, and other information. For example, after the user puts in the tableware, the user can select the appropriate washing mode through the control panel on the door body 50, and start the dishwasher to begin the automatic washing process. During the washing process, the user can always know the working progress of the dishwasher through the display screen.

[0052] The partition 20 of the embodiment is arranged inside the inner container 10, and can be a partition plate. The partition 20 divides the washing cavity 100 into an upper washing cavity 101 and a lower washing cavity 102. The partition 20 and the inner wall of the inner container 10 can be detachably connected. For example, the inner wall of the inner container 10 is provided with a plurality of mounting slots arranged at intervals in the height direction, and the partition 20 can be mounted in the mounting slots at different positions according to actual needs. By changing the position of the partition 20 in the mounting slots, the volume of the upper washing cavity 101 and the lower washing cavity 102 can be flexibly adjusted. When more large tableware needs to be cleaned, the partition 20 can be mounted at a higher position to increase the volume of the lower washing cavity 102 to accommodate the large tableware. When more small tableware needs to be cleaned, the partition 20 can be mounted at a lower position to expand the space of the upper washing cavity 101. This flexible adjustment design can better meet the diversified needs of different users for cleaning different tableware and improve the use efficiency of the dishwasher.

[0053] During the washing cycle of the dishwasher, the filter assembly 30 can effectively intercept food residues in the washing water to prevent the residues from entering the washing cycle again and affecting the cleaning effect. After a long time of use, the filter assembly 30 needs to be cleaned.

[0054] The filter assembly 30 of the embodiment is mounted on the partition 20 closer to one side of the door body 50 than the back plate of the inner container 10, which is a core innovative point of the application. This position design fully considers the convenience of user operation. When the user opens the door body 50 of the dishwasher, the filter assembly 30 is directly presented to the user, and the user can intuitively and clearly observe the use state of the filter assembly 30, such as whether there is residue blockage, whether the filter screen is damaged, etc.

[0055] In one embodiment, the filter assembly 30 and the partition 20 are detachably connected, for example, buckling connection. This connection method is simple and convenient, and the user does not need to use additional tools. By simple pressing or rotating action, the filter assembly 30 can be easily taken off or installed back on the partition 20.

[0056] In the embodiment, when the user cleans the residues in the filter assembly 30, due to the position advantage of the filter assembly 30 close to the door body 50, i.e., close to the human body, the user does not need to stretch his hand greatly or search for the residues with great effort, but can easily complete the cleaning operation, greatly improving the convenience of operation, reducing the difficulty of the user to clean the filter assembly 30, and making the cleaning work more efficient and easy.

[0057] Please refer to Figure 2 and Figure 3 , Figure 3 are Figure 2 enlarged views of position A in FIG. 8.

[0058] In some embodiments, the filtering assembly 30 comprises a first filtering member 31 and a second filtering member 32.

[0059] The first filtering member 31 covers the sink 201 and is provided with an opening. The first filtering member 31 can be flat, and is provided with a flow guide slope 311 that is inclined downward toward the opening and a first filter screen on the flow guide slope 311. When the dishwasher is working, the washing water after washing the tableware first flows through the flow guide slope 311. Due to the inclined design of the flow guide slope 311, the washing water can flow more smoothly under the action of gravity. The first filter screen performs the first filtering at this time, and can intercept larger food residues and other impurities. The filtered washing water flows into the sink 201 through the first filter screen.

[0060] The second filtering member 32 penetrates the opening of the first filtering member 31 and extends into the sink 201. The second filtering member 32 can be columnar, and is provided with a residue guide opening 321 and a residue collection cavity 322 that are connected in communication, and the residue guide opening 321 cooperates with the flow guide slope 311. When the food residues slide down along the flow guide slope 311, they enter the residue collection cavity 322 through the residue guide opening 321. The side wall of the residue collection cavity 322 is provided with a second filter screen that is in communication with the sink 201. The washing water entering the residue collection cavity 322 passes through the second filter screen to perform the second filtering, further intercepting the remaining small impurities, so that only relatively clean washing water flows into the sink 201 through the second filter screen, and a more fine filtering effect is achieved.

[0061] Please refer to Figure 2 and Figure 4 , Figure 4 The structural schematic diagram of the partition 20, the filtering assembly 30 and the spray arm 42 provided in the embodiment is shown.

[0062] In some embodiments, the dishwasher further comprises an upper cavity waterway system 40 for washing the upper washing cavity 101, and the upper cavity waterway system 40 comprises a washing pump 41 and a spray arm 42. Among them, the washing pump 41 is a key component. The water suction port of the washing pump 41 is in communication with the sink 201, and its function is to suck out the washing water in the sink 201 that has been preliminarily filtered by the filtering assembly 30. When the dishwasher starts the washing program, the washing pump 41 starts to work, provides power for the entire upper cavity waterway system 40, so that the washing water can circulate in the system, and ensures that the tableware is fully cleaned.

[0063] The spray arm 42 is installed on the partition 20 and located in the upper washing cavity 101, and its water outlet is in communication with the water outlet of the washing pump 41. The washing pump 41 pressurizes and delivers the washing water sucked from the sink 201 to the spray arm 42, and the spray arm 42 sprays high-pressure washing water on the tableware in the upper washing cavity 101 through its water outlet. The spray arm 42 can have multiple water outlets, which can cover multiple tableware at the same time, effectively improving the washing efficiency.

[0064] In one embodiment, the upper cavity waterway system 40 further comprises a water storage cup 45, the water inlet of the water storage cup 45 is communicated with the water tank 201, and the water outlet is communicated with the water suction port of the washing pump 41. Exemplarily, the water storage cup 45 is arranged on the back plate of the inner container 10 and is communicated with the water tank 201 through a pipeline extending in the front-rear direction. The water storage cup 45 can store a certain amount of washing water during the washing process to ensure that the washing pump 41 can continuously and stably suck water.

[0065] In one embodiment, the upper cavity waterway system 40 further comprises a drainage pump 43, the water suction port of the drainage pump 43 is communicated with the residue collecting cavity 322, and the drainage pump 43 is used to drain the residue and sewage in the residue collecting cavity 322 out of the dishwasher after the washing program ends. During the washing process, the food residue intercepted by the filter assembly 30 will accumulate in the residue collecting cavity 322, and the sewage in the residue collecting cavity 322 will also increase with the continuous circulation of the washing water. After the drainage pump 43 is started, the residue and the sewage can be sucked out together to ensure the cleanliness of the inside of the dishwasher.

[0066] In one embodiment, referring to Figure 5 and Figure 6 , the upper cavity waterway system 40 further comprises a drain pipe 44, the drain pipe 44 is communicated with the water outlet of the drainage pump 43. In order to prevent water leakage, the center of the pipeline at the highest position of the drain pipe 44 is higher than the upper surface of the cavity bottom wall of the upper washing cavity 101, and the height difference H satisfies: H≥5mm. In this way, the siphon principle can be used to ensure that the water in the upper washing cavity 101 will not flow back or leak due to the too low position of the drain pipe 44 under normal use conditions.

[0067] In one embodiment, referring to Figure 6 , an installation groove 103 is formed in the inner side of the inner container 10. Exemplarily, the installation groove 103 is formed in the back plate of the inner container 10. The installation groove 103 provides installation space for the washing pump 41 and the drainage pump 43, so that the washing pump 41 and the drainage pump 43 can be installed in the installation groove 103, thereby hiding these components and making the internal structure of the dishwasher more compact and effectively saving space. Such an arrangement not only helps to improve the utilization rate of the internal space of the dishwasher, but also makes the layout of the components more reasonable and facilitates the cooperative work of the components.

[0068] In one embodiment, continuing to refer to Figure 6 In one embodiment, the water storage cup 45 is arranged in the installation groove 103, specifically, the water storage cup 45 can be connected with the partition 20. Among them, the installation groove 103 extends along the width direction of the inner container 10, and the washing pump 41 and the drainage pump 43 are respectively located on the two sides of the water storage cup 45 in the width direction of the inner container 10, thereby further improving the structural compactness of the dishwasher.

[0069] In one embodiment, please refer to Figure 1 The dishwasher further comprises a lower cavity waterway system 60 for washing the lower washing cavity 102, which is installed on the bottom plate of the inner tank 10. The structure of the lower cavity waterway system 60 can refer to the upper cavity waterway system 40. The lower cavity waterway system 60 is also provided with a washing pump, the suction port of which is communicated with the corresponding water tank at the bottom plate of the inner tank 10, which provides power for the washing of the lower washing cavity 102 and makes the washing water circulate in the system. The spray arm is installed above the bottom plate of the inner tank 10 and located in the lower washing cavity 102, which sprays the washing water pressurized by the washing pump to the dishes in the lower washing cavity 102. The lower cavity waterway system 60 can also be provided with a water storage cup structure to ensure the stability of the water suction of the washing pump and maintain the circulation of the washing water. The bottom plate of the inner tank 10 is also provided with a residue collection cavity, and the drain pump is communicated with the residue collection cavity to discharge the residue and sewage after the washing is completed. In this way, the lower washing cavity 102 can work cooperatively with the upper washing cavity 101 to further improve the overall washing efficiency and effect of the dishwasher.

[0070] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
