Description

Technical Field

[0001] This application relates to the field of washing equipment technology, and more particularly to a dishwasher. Background Technology

[0002] A dishwasher is a household appliance used to automatically clean dishes, cookware, and tableware. It removes dirt and food residue from dishes by spraying high-pressure water through spray arms.

[0003] In dishwashers of this technology, a filter is installed at the bottom of the sink to filter impurities in the water flowing towards the washing pump and spray arms, preventing them from clogging. After the washing cycle ends, residue often adheres to the inner surface of the filter in the sink, requiring the user to manually remove the filter for cleaning and then reinstall it. This process is cumbersome, time-consuming, and laborious. Utility Model Content

[0004] This application provides a dishwasher that solves the technical problem that the filter screen needs to be manually disassembled for cleaning.

[0005] This application provides a dishwasher, including:

[0006] The inner liner has a washing chamber.

[0007] A water storage unit is located at the bottom of the inner tank. The water storage unit has a water tank with the opening facing upwards and connected to the washing chamber.

[0008] The first filter screen is installed inside the water tank;

[0009] The water storage component also includes:

[0010] The water inlet chamber is independent of the water tank;

[0011] The water injection channel is connected to the water inlet chamber and is also used to connect to the water source;

[0012] A partition is provided between the water tank and the water inlet chamber. The partition is equipped with spray holes, which are connected to the water inlet chamber and the portion of the water tank located inside the first filter screen. The water outlet direction of the spray holes is towards the inner side of the first filter screen.

[0013] The drainage channel is connected to the part of the water tank located inside the first filter screen.

[0014] In this embodiment of the dishwasher, water injected through the water inlet channel first flows into the water inlet chamber, and then is sprayed through the spray nozzles onto the inner surface of the first filter screen. This serves two purposes: firstly, it fills the water tank with water, which then flows through the first filter screen and out through the water outlet channel to the washing pump and spray arms to clean the dishes; secondly, it rinses the inner surface of the first filter screen, washing away any residue adhering to it and causing it to fall to the bottom of the water tank. During the drainage process after each stage of the main wash, cold rinse, and hot rinse, the washed-off residue is discharged with the water flow in the water tank through the drain channel, achieving automatic rinsing of residue on the first filter screen. This eliminates the need for manual disassembly and cleaning of the filter screen, saving time and effort, and reducing the possibility of damage to the first filter screen or water storage components due to frequent disassembly and reassembly.

[0015] In some embodiments of this application, the partition forms the bottom of the water tank; the water inlet cavity is located below the partition.

[0016] With this configuration, water is injected into the inlet chamber through the water injection channel. The water in the inlet chamber can then flow upwards along the nozzles toward the inner surface of the first filter screen to wash away the residue adhering to the inner surface of the first filter screen.

[0017] In some embodiments of this application, the water inlet cavity is at least partially annular;

[0018] There are multiple nozzles, which are arranged at intervals along the extension direction of the water inlet chamber.

[0019] With this configuration, multiple nozzles can disperse the water flow, increasing the coverage area of ​​the water flow sprayed from the inlet chamber onto the first filter screen. This increases the area of ​​the first filter screen that the water flow can wash over, improving the rinsing efficiency of the residue on the first filter screen.

[0020] In some embodiments of this application, the water storage device further includes:

[0021] A connecting member is provided on the side of the partition that is away from the water tank. The connecting member has a hollow inner cavity, with one end of the inner cavity near the partition and the other end away from the partition penetrating through the connecting member.

[0022] A cover plate is fitted onto the port of the connecting member away from the partition, and the partition, connecting member and cover plate together form a water inlet cavity.

[0023] In some embodiments of this application, the sidewall of the connecting member is provided with a water inlet, which is connected to the water injection channel.

[0024] With this configuration, the side wall of the connecting piece facing the water inlet cavity can guide the water flowing into the water inlet cavity from the water inlet, so that the water flowing into the water inlet cavity from the water inlet cavity can quickly flow to the end of the water inlet cavity away from the water inlet, thereby improving the efficiency of water entering the water tank from the spray hole and shortening the washing process time.

[0025] In some embodiments of this application, the first filter screen is tubular, with its bottom end facing the bottom of the water tank, and the diameter of the first filter screen decreases from bottom to top.

[0026] With this configuration, the sidewall of the first filter screen is inclined from bottom to top toward the axis of the first filter screen. The residue attached to the inner surface of the first filter screen is more likely to fall downward under its own gravity, making it less likely for residue in the washing water to adhere to the inner surface of the first filter screen, thus reducing the amount of residue attached to the inner surface of the first filter screen.

[0027] In some embodiments of this application, the bottom of the sidewall of the first filter screen is provided with a notch, which corresponds to the port of the drainage channel near the end of the water tank.

[0028] With this design, the notch can avoid obstructing the drain channel near the sink end, reducing the obstruction of the drain channel near the sink end by the first filter screen. This allows the mixture of sewage and residue in the part of the sink inside the first filter screen to be more easily discharged from the drain channel, improving the dishwasher's drainage efficiency.

[0029] In some embodiments of this application, the dishwasher further includes:

[0030] The spray arm is located inside the washing chamber;

[0031] The washing pump has a pump inlet and a pump outlet, with the pump outlet connected to the spray arm;

[0032] The water storage device is also equipped with a water outlet channel, which is connected to the pump inlet and the part of the water tank located outside the first filter screen.

[0033] With this configuration, the residue washed down by the spray arm mixes with the washing water and flows downwards under gravity. It first flows from the top port of the first filter screen into the part of the water tank located inside the first filter screen. The residue in the washing water is intercepted by the first filter screen, reducing the amount of residue in the washing water flowing into the part of the water tank located outside the first filter screen. This reduces the amount of residue in the washing water flowing to the water outlet channel, washing pump, and spray arm, making it less likely for the washing pump and spray arm to be clogged by residue.

[0034] In some embodiments of this application, the dishwasher further includes a flat filter screen disposed on top of the first filter screen and covering the opening of the sink.

[0035] With this configuration, the flat filter screen can filter the washing water that flows directly from the washing chamber into the part of the water tank located outside the first filter screen without passing through it. This intercepts the residue in the washing water on the top surface of the flat filter screen, thereby reducing the amount of residue in the washing water flowing directly from the washing chamber into the part of the water tank located outside the first filter screen. This reduces the amount of residue in the washing water flowing to the water outlet channel, washing pump, and spray arm, making it less likely for the washing pump and spray arm to be clogged by residue.

[0036] In some embodiments of this application, the dishwasher further includes a second filter screen, the pore size of which is larger than that of the first filter screen; the second filter screen is disposed on top of the first filter screen, and a portion of the second filter screen extends into the washing chamber.

[0037] With this design, the second filter can intercept larger residues in the washing water on its outer side, that is, on the side of the second filter that is away from its own axis. This makes it less likely for larger residues to flow into the first filter with the washing water, thus reducing the possibility of larger residues being discharged into the sewer through the drain channel and causing sewer blockage.

[0059] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0060] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0061] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0062] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0063] To address the issue of dishwashers requiring manual removal and cleaning of their filters in related technologies, this application provides a dishwasher with an inlet chamber separate from the water tank on the water storage component. Spray nozzles are constructed on the partition between the inlet chamber and the water tank, communicating with both the inlet chamber and the portion of the water tank located inside the first filter. The water outlet direction of the spray nozzles is towards the first filter. Water is injected into the inlet chamber through the water injection channel, and the water is sprayed from the spray nozzles into the water tank, rinsing the inner surface of the first filter. This washes away residue adhering to the inner surface of the first filter, causing it to fall to the bottom of the water tank and be discharged through the drain channel with the water flow. This achieves automatic rinsing of residue on the first filter, eliminating the need for manual removal and cleaning, saving time and effort, and reducing the possibility of damage to the first filter or the water storage component due to frequent removal and installation of the first filter.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] refer to Figure 1 The dishwasher provided in this application embodiment includes a cabinet, a door, a dish rack, and a spray arm 40. The cabinet may include a shell and an inner liner 10, with the inner liner 10 disposed inside the shell to form the appearance of the cabinet. A washing chamber 110 is formed inside the inner liner 10. The front side of the washing chamber 110 has a pull-out opening, which communicates with the washing chamber 110.

[0066] It should be noted that in the description of the embodiments of this application, "front side" refers to the side of the dishwasher facing the user when it is in normal use.

[0067] The door is rotatably connected to the box body, and the door is used to open or close the pull-out opening.

[0068] The dish rack is removably installed within the washing chamber 110 via a pull-out opening. The dish rack is used to hold tableware or cookware. Tableware can be placed inside the dish rack from the top. When it is necessary to place tableware or cookware in the dish rack, at least a portion of the dish rack can be pulled out of the washing chamber 110 to facilitate placement. After placement, the dish rack can be pushed back into the washing chamber 110. Pulling at least a portion of the dish rack out of the washing chamber 110 reduces the obstruction of the space above the dish rack by the cabinet, making it easier to place or remove tableware from the dish rack.

[0069] The number of bowls can be one or more.

[0070] In implementations where there are two or more dish racks, multiple dish racks can be arranged at intervals along the height of the inner liner 10 within the washing chamber 110. This improves the space utilization within the washing chamber 110 and, by distributing the tableware into multiple dish racks, reduces overlap and obstruction between the tableware, minimizes cleaning dead spots, and thus improves the cleaning effect on the tableware.

[0071] refer to Figure 1 The spray arm 40 is disposed within the washing chamber 110. The spray arm 40 may be configured with a spray chamber and multiple nozzles. The spray chamber is used to allow washing water to flow in. The washing water can be tap water or tap water mixed with detergent. The nozzles can spray water towards the dish rack to rinse away stains and food residue on the tableware or kitchen utensils inside the rack, thereby cleaning the tableware or kitchen utensils.

[0072] In some possible implementations of the embodiments of this application, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 The dishwasher may also include a water reservoir 20, which may be located at the bottom of the inner tank 10. The water reservoir 20 is configured with an upward-facing water tank 211, which is connected to the washing chamber 110 through a top opening, so that water in the washing chamber 110 can flow downward into the water tank 211.

[0073] In some possible implementations of the embodiments of this application, reference is made to Figure 5 and Figure 6 The water storage component 20 may also be constructed with a water injection channel 213, which is connected to the water tank 211 and is used to connect to an external water source (such as tap water).

[0074] The dishwasher may include a water inlet pipe, one end of which may be connected to a water storage container 20, and the cavity of the water inlet pipe may be connected to a water inlet channel 213. The other end of the water inlet pipe may extend outside the cabinet for connection to an external water source. The external water source may flow through the water inlet pipe into the water inlet channel 213, and then into the water tank 211.

[0075] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 7 The water storage component 20 may also be configured with a water outlet channel 215, which is connected to the water tank 211.

[0076] refer to Figure 2 The dishwasher may also include a wash pump 50, which may be located below the inner tank 10. The wash pump 50 may have a pump inlet 501, which may be connected to the water outlet channel 215.

[0077] refer to Figure 2 The washing pump 50 may also have a pump outlet 502, which may be connected to the spray chamber of the spray arm 40.

[0078] Water injected into the water tank 211 through the water injection channel 213 flows into the washing pump 50 through the pump inlet 501. After being accelerated and pressurized by the washing pump 50, it flows from the pump outlet 502 to the spray arm 40 to increase the flow rate and water pressure of the water sprayed from the spray arm 40, thereby improving the cleaning effect on the tableware.

[0079] In some possible implementations of the embodiments of this application, reference is made to Figure 1 and Figure 2 The dishwasher may also include a water distribution valve 80, which may be located at the bottom of the inner tub 10. The water distribution valve 80 is connected between the pump outlet 502 of the washing pump 50 and the spray arm 40. Water from the pump outlet 502 of the washing pump 50 can flow selectively to one or more spray arms 40 through the water distribution valve 80, allowing the dishwasher to switch between different spray arms 40 to spray water during different washing stages, achieving efficient washing and water and energy saving.

[0080] In some possible implementations of the embodiments of this application, ah can be considered Figure 6 and Figure 7 The dishwasher also includes a first filter 30, which is disposed within the sink 211. The first filter 30 may be tubular, for example, it may be approximately cylindrical or frustum-shaped (see reference). Figure 7 The filter screen 30 can be a prismatic, frustum-shaped, or other tubular shape, as long as both ends of the first filter screen 30 pass through it along its axial direction. The sidewalls of the first filter screen 30 have mesh openings.

[0081] refer to Figure 6 The axis of the first filter screen 30 can be roughly aligned with the height direction of the water tank 211. That is, the bottom end of the first filter screen 30 faces the bottom of the water tank 211, and the top end of the first filter screen 30 faces away from the bottom of the water tank 211.

[0082] refer to Figure 6 The water outlet channel 215 is connected to the portion of the water tank 211 located outside the first filter screen 30. Specifically, the portion of the water tank 211 located outside the first filter screen 30 is the area enclosed by the side of the first filter screen 30 away from its own axis and the tank wall of the water tank 211.

[0083] The dishwasher's washing program can include stages such as main wash, cold rinse, hot rinse, and drying. During each of the main wash, cold rinse, and hot rinse stages, the spray arm 40 sprays washing water onto the dishes to rinse away stains and food residue. The washed-off residue mixes with the washing water and flows downward under gravity. It first flows from the top port of the first filter screen 30 into the part of the water tank 211 located inside the first filter screen 30. The residue in the washing water is intercepted by the first filter screen 30, reducing the amount of residue in the washing water flowing into the part of the water tank 211 located outside the first filter screen 30. This reduces the amount of residue in the washing water flowing to the water outlet channel 215, the washing pump 50, and the spray arm 40, making the washing pump 50 and the spray arm 40 less prone to clogging by residue.

[0084] The washing water sprayed from the spray arm 40 is filtered by the first filter screen 30 and then flows back to the spray arm 40 through the washing pump 50 to continue rinsing the dishes. This improves the utilization rate of the washing water, reduces the amount of water required to wash the dishes, and lowers the water consumption of the dishwasher.

[0085] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 7 The diameter of the first filter screen 30 decreases from bottom to top. For example, the first filter screen 30 can be a frustum-shaped tube that is smaller at the top and larger at the bottom (see reference). Figure 7 Or a frustum-shaped tube with a smaller top and a larger bottom, etc., so that the side wall of the first filter screen 30 is inclined from bottom to top toward the axis of the first filter screen 30, and the residue attached to the inner side of the first filter screen 30 is easy to fall downward under its own gravity, making it difficult for residue in the washing water to adhere to the inner side of the first filter screen 30, thus reducing the amount of residue attached to the inner side of the first filter screen 30.

[0086] In some possible implementations of the embodiments of this application, reference is made to Figure 8The water storage component 20 may also be constructed with a drainage channel 214, which is connected to the portion of the water tank 211 located inside the first filter screen 30. The portion of the water tank 211 located inside the first filter screen 30 is the area enclosed by the side of the first filter screen 30 facing its own axis and the tank wall and bottom of the water tank 211.

[0087] During each stage of the main wash, cold rinse, and hot rinse, water needs to be injected into the water tank 211 through the water injection channel 213 for washing. After washing, the water in the washing chamber 110 flows from the top port of the first filter screen 30 to the part of the water tank 211 located inside the first filter screen 30, and then is discharged to the sewer or outside the tank through the drain channel 214. The residue trapped inside the first filter screen 30 is also discharged from the drain channel 214 with the water flow.

[0088] In some possible implementations of the embodiments of this application, reference is made to Figure 2 The dishwasher may also include a drain pump 90, which is connected to the water reservoir 20 and communicates with the drain channel 214. The drain pump 90 is used to increase the discharge rate of the mixture of wastewater and residue generated during the washing process.

[0089] In some possible implementations of the embodiments of this application, reference is made to Figure 8 and Figure 9 The bottom sidewall of the first filter screen 30 may have a notch 301, which corresponds to the port of the drain channel 214 near the end of the sink 211. The notch 301 can avoid obstructing the port of the drain channel 214 near the sink 211, reducing the obstruction of the drain channel 214 near the sink 211 by the first filter screen 30. This allows the mixture of sewage and residue in the portion of the sink 211 located inside the first filter screen 30 to be more easily discharged from the drain channel 214, improving the drainage efficiency of the dishwasher.

[0090] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 8 The water storage component 20 can also be constructed with a water inlet chamber 212, which is independent of the water tank 211. That is, the water inlet chamber 212 and the water tank 211 are two independent chambers.

[0091] refer to Figure 6 and Figure 8 The water storage component 20 may further include a partition 220, which separates the water tank 211 and the water inlet chamber 212. The partition 220 is configured with nozzles 221, which communicate with the portions of the water inlet chamber 212 and the water tank 211 located inside the first filter screen 30. The water outlet direction of the nozzles 221 is towards the inner surface of the first filter screen 30.

[0092] During the washing process, residues in the washing water adhere to the inner surface of the first filter screen 30.

[0093] During the main wash, cold rinse, and hot rinse stages, water injected through the water injection channel 213 first flows to the water inlet chamber 212, and then is sprayed through the spray nozzle 221 onto the inner surface of the first filter screen 30. This serves two purposes: firstly, it fills the water tank 211 with water, which then flows through the first filter screen 30 and out through the water outlet channel 215 to the washing pump 50 and spray arm 40 to clean the dishes; secondly, it rinses the inner surface of the first filter screen 30, washing off any residue adhering to it and causing it to fall to the bottom of the water tank 211. During the drainage process after each stage of the main wash, cold rinse, and hot rinse, the washed-off residue is discharged with the water flow in the water tank 211 through the drain channel 214, achieving automatic rinsing of residue on the first filter screen 30 without the need for manual disassembly and cleaning. This saves time and effort and reduces the possibility of damage to the first filter screen 30 or the water storage component 20 due to frequent disassembly and reassembly.

[0094] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 8 The partition 220 forms the bottom of the water tank 211. The partition 220 may be plate-shaped. The water inlet chamber 212 is located below the partition 220, that is, the water tank 211 is located above the partition 220, and the water inlet chamber 212 is located below the partition 220.

[0095] The axis of the nozzle 221 can be tilted at a certain angle relative to the axis of the first filter screen 30 so that the nozzle 221 can spray water toward the inner side of the first filter screen 30. Water is injected into the water inlet chamber 212 through the water injection channel 213, and the water in the water inlet chamber 212 can spray water from bottom to top toward the inner side of the first filter screen 30 along the nozzle 221 to wash away the residue attached to the inner side of the first filter screen 30.

[0096] In some other possible implementations of this application, the partition 220 may be located at the bottom of the side wall of the water storage component 20, and the partition 220 may form part of the tank wall of the water tank 211. The water inlet cavity 212 may be located on the side of the partition 220 away from the water tank 211, and the water inlet cavity 212 may surround at least a portion of the outer periphery of the partition 220. That is, the water inlet cavity 212 surrounds at least a portion of the outer periphery of the water tank 211.

[0097] The nozzle 221 can be located at a height below the bottom of the first filter screen 30. The axis of the nozzle 221 can be inclined relative to the bottom of the water tank 211 so that the nozzle 221 can discharge water toward the inner side of the first filter screen 30. Water is injected into the water inlet chamber 212 through the water injection channel 213, and the water in the water inlet chamber 212 can be discharged along the nozzle 221 from the outside to the inside toward the inner side of the first filter screen 30 to wash away the residue attached to the inner side of the first filter screen 30.

[0098] In some possible implementations of the embodiments of this application, the water inlet chamber 212 may be at least partially annular, that is, the water inlet chamber 212 may be a closed annular chamber; or it may be an open annular chamber, or an open-loop chamber (see reference). Figure 10 ).

[0099] There can be multiple nozzles 221, which can be arranged at intervals along the extension direction of the water inlet chamber 212. Multiple nozzles 221 can disperse the water flow and increase the coverage area of ​​the water flow sprayed from the water inlet chamber 212 to the first filter screen 30, thereby increasing the area of ​​the first filter screen 30 that the water flow can wash over and improving the washing efficiency of residues on the first filter screen 30.

[0100] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 10 The water storage component 20 may further include a connecting member 230, which is disposed on the side of the partition 220 opposite to the water tank 211. The connecting member 230 has a hollow inner cavity, with one end of the inner cavity near the partition 220 and the other end opposite to the partition 220 respectively penetrating through the connecting member 230. The connecting member 230 and the partition 220 together form an inner cavity with an opening at the end opposite to the partition 220.

[0101] refer to Figure 6 and Figure 7 The water storage component 20 may also include a cover plate 240, which covers the port of the connecting member 230 away from the partition 220. The partition 220, the connecting member 230 and the cover plate 240 together form a water inlet cavity 212.

[0102] In some embodiments, reference Figure 10 The connecting member 230 can be integrally formed with the partition 220, which improves the production efficiency of the water storage component 20, reduces the splicing gap between the connecting member 230 and the partition 220, and improves the reliability of the connection between the connecting member 230 and the partition 220.

[0103] The cover plate 240 can be welded to the connecting member 230 to prevent water leakage between the connecting member 230 and the cover plate 240, so that the cover plate 240 can be enclosed with the partition 220 and the connecting member 230 to form a sealed water inlet cavity 212.

[0104] Understandably, the cover plate 240 can also be threaded to the connecting member 230, or a sealing ring can be provided between the cover plate 240 and the connecting member 230, and then fixed with screws or clips.

[0105] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 10 The side wall of the connecting member 230 may be configured with a water inlet 231, which is connected to the water injection channel 213. The side wall of the connecting member 230 facing the water inlet cavity 212 can guide the water flowing into the water inlet cavity 212 from the water inlet 231, so that the water flowing into the water inlet cavity 212 from the water inlet 231 can quickly flow to the end of the water inlet cavity 212 away from the water inlet 231, thereby improving the efficiency of water entering the water tank 211 from the spray hole 221 and shortening the washing process time.

[0106] In some possible implementations of the embodiments of this application, reference is made to Figure 1 , Figure 4 and Figure 6 The dishwasher may also include a planar filter 60, which is generally planar. The aperture of the mesh on the planar filter 60 may be approximately the same as the aperture of the mesh on the first filter 30. The planar filter 60 is disposed on top of the first filter 30 and covers the opening of the sink 211.

[0107] The flat filter screen 60 can filter the washing water that flows directly from the washing chamber 110 to the portion of the water tank 211 located outside the first filter screen 30 without passing through the first filter screen 30, so as to intercept the residue in the washing water on the top surface of the flat filter screen 60. This reduces the amount of residue in the washing water that flows directly from the washing chamber 110 to the portion of the water tank 211 located outside the first filter screen 30, thereby reducing the amount of residue in the washing water flowing to the water outlet channel 215, the washing pump 50 and the spray arm 40, making the washing pump 50 and the spray arm 40 less likely to be blocked by residue.

[0108] In some possible implementations of the embodiments of this application, reference is made to Figure 1 , Figure 4 , Figure 6 and Figure 7The dishwasher may also include a second filter 70, the mesh size of which is larger than that of the first filter 30. The axis of the second filter 70 may be approximately collinear with the axis of the first filter 30. The second filter 70 is disposed on top of the first filter 30, and a portion of the second filter 70 extends into the washing chamber 110. The mesh of the second filter 70 is formed on one radial side of the second filter 70. The second filter 70 can intercept larger residues in the washing water on its outer side, that is, on the side of the second filter 70 opposite to its own axis, making it less likely for larger residues to flow into the first filter 30 with the washing water, thus reducing the possibility of larger residues being discharged into the sewer through the drain channel 214 and causing sewer blockage.

[0109] refer to Figure 6 In the implementation of the dishwasher including a second filter 70 and a flat filter 60, a portion of the second filter 70 extends above the flat filter 60, and the mesh of the second filter 70 is located above the flat filter 60. This reduces the possibility that larger residues will flow with the washing water to the portion of the sink 211 located outside the first filter 30, thereby reducing the possibility that larger residues will clog the washing pump 50 and the spray arm 40.
