Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a slag collection and filtration device and a dishwasher. Background Technology

[0002] During operation, contaminants such as residual oil and food residue on the surface of the dishes are washed down by the washing water and enter the drainage system. To prevent the drainage pipes from becoming clogged and to improve washing efficiency, dishwashers are usually equipped with a filter.

[0003] In practical use, when there is little residue, it will be directly pumped away by the drain pump along with the water flow. However, when there is a lot of residue in the water flow, under the suction of the washing pump, a large amount of residue can easily clog the side of the filter element facing the washing pump. A large amount of residue can also adhere to the filter screen surface of the filter element, which will reduce the water flow and cause problems such as reduced drainage efficiency and slowed water circulation speed.

[0004] Therefore, it is urgent to solve the technical problem that residue easily clogs the filter elements, leading to a decrease in water flow. Summary of the Invention

[0005] This invention provides a slag collection and filtration device and a dishwasher to solve the technical problem that slag easily clogs the fine filter, leading to a decrease in water flow.

[0006] To achieve the above objectives, the present invention provides a slag collection and filtration device, comprising:

[0007] A water cup, wherein the water cup has a water passage cavity;

[0008] A filter assembly is disposed within the water passage chamber. The filter assembly includes an agitator and an inner filter element. The agitator is rotatably disposed within the water passage chamber, and a receiving cavity is formed inside the agitator. At least a portion of the inner filter element extends into the receiving cavity.

[0009] A drive assembly is disposed in the water cup and is used to drive the agitator to rotate so that the agitator disturbs the water flow and washes the inner filter.

[0010] This invention provides a slag collection and filtration device. The filtration assembly includes an agitator and an inner filter element. The agitator is rotatably disposed within a water passage chamber, forming a receiving cavity inside. At least a portion of the inner filter element extends into this receiving cavity. When the driving assembly drives the agitator to rotate, the agitator causes the surrounding water to form a circumferential flow and local turbulence, guiding the water flow around the inner filter element. This allows the inner filter element to be continuously flushed by water flow from different directions, achieving a cleaning effect. Because the inner filter element is located in the turbulent flow area inside the agitator, oil stains and fine residues adhering to the surface of the inner filter element are more easily detached under the shearing action of the water flow. Simultaneously, the rotation process breaks up the stable accumulation layer of pollutants formed on the inner filter element, causing the residue to redisperse with the water flow and be carried away by subsequent drainage. This solves the problem of localized clogging of the inner filter element, which affects water flow and reduces return water efficiency.

[0011] In one possible implementation, the inner wall of the agitator is provided with a turbulence structure. The turbulence structure is disposed on the inner wall of the agitator, and when the agitator rotates, the turbulence structure guides the water flow to be disturbed so as to flush the inner filter element.

[0012] In one possible implementation, the turbulence structure includes a turbulence plate, one side of which is connected to the inner wall of the accommodating cavity, and the other side of which extends toward the interior of the accommodating cavity and has a distance H, where H > 0, between it and the inner filter element.

[0013] In one possible implementation, the height L1 of the spoiler and the height L2 of the agitator satisfy the condition: 0.5 ≤ L1 / L2 ≤ 0.9.

[0014] In one possible implementation, the baffle is circumferentially twisted along the inner wall of the receiving cavity along the height direction of the agitator, and the baffle has a twist angle α between it and the radial plane of the agitator, wherein 30°≤α≤60°.

[0015] In one possible implementation, the agitator has a plurality of first filter holes on its periphery so that the accommodating cavity and the outside of the agitator are connected through the first filter holes.

[0016] In one possible implementation, the drive assembly includes a drive member and a transmission unit, the drive member being disposed on the outer wall of the water cup, and the transmission unit being drively connected between the drive member and the agitator.

[0017] In one possible implementation, the drive element is a motor having a drive shaft extending into the water cup, and the transmission unit includes:

[0018] A drive gear, which is connected to the drive shaft;

[0019] A driven gear is disposed on the outer periphery of the agitator, and the driven gear meshes with the driving gear.

[0020] In one possible implementation, the water cup also has a mounting cavity located to the side of the water passage cavity and communicating with it. The drive gear is located inside the mounting cavity, and the outer wall of the mounting cavity has a clearance hole. The drive shaft extends into the mounting cavity through the clearance hole, and a seal is provided between the drive shaft and the clearance hole.

[0021] In one possible implementation, the water passage cavity has a first guide portion, and the bottom of the agitator has a second guide portion disposed along the circumference of the agitator;

[0022] One of the first guide portion and the second guide portion is a groove, and the other of the first guide portion and the second guide portion is a slide rail. The slide rail is slidably disposed in the groove to guide the circumferential rotation of the agitator.

[0023] In one possible implementation, the agitator has a third guide portion at its top, the inner filter has an outward flange at its top, and a fourth guide portion is provided on the lower surface of the outward flange, the fourth guide portion and the third guide portion cooperating with each other.

[0024] One of the fourth guide portion and the third guide portion is a groove, and the other of the fourth guide portion and the third guide portion is a slide rail. The slide rail is slidably disposed in the groove to guide the circumferential rotation of the agitator.

[0025] In one possible implementation, the sludge collection and filtration device further includes an image recognition component and a controller, the image recognition component and the controller being electrically connected, the image recognition component being disposed on the inner wall of the water passage chamber, and the image recognition component being used to acquire images of the residue accumulated inside the inner filter element;

[0026] When the image recognition component detects that the amount of residue accumulated inside the inner filter element has reached a preset amount, it controls the driving component to drive the agitator to rotate.

[0027] In one possible implementation, the sludge collection and filtration device further includes an illumination element disposed on the inner wall of the water passage chamber, the illumination element being electrically connected to the controller, and the illumination element being used to illuminate the image recognition component.

[0028] The present invention also provides a dishwasher, including the above-described slag collection and filtering device.

[0029] The slag collection and filtration device and dishwasher provided by the present invention, because the baffle plate has a torsion angle α, can exert a continuous circumferential deflection effect on the water flow entering the accommodating cavity when the agitator rotates, and form a compound disturbance between axial advancement and radial tumbling, so that the water flow repeatedly washes the inner filter element to reduce the adhesion and deposition of food residue on the surface of the inner filter element.

[0030] The slag collection and filtration device and dishwasher provided by this invention, because the control logic for the self-cleaning of the filter component is triggered based on the actual degree of contamination, the agitation action of the agitator can intervene in the slag accumulation process more promptly, avoiding long-term adhesion of slag and solidification on the surface of the inner filter component, thereby helping to reduce the problem of filter component blockage, maintain the flow capacity of the water passage chamber, reduce the resistance of circulating water flow, and to a certain extent reduce the frequency of manual disassembly and cleaning, and improve the operational stability of the filter component during long-term use.

[0031] The slag collection and filtration device and dishwasher provided by this invention can obtain a clear image of the slag when slag adheres to the surface of the inner filter element and causes obstruction or accumulation due to changes in water flow. Based on this image, the image recognition component can determine the amount of slag accumulation, enabling the controller to more accurately trigger the drive component to work based on the image recognition result of the image recognition component. This allows for timely monitoring and proactive intervention of the slag accumulation state on the surface of the inner filter element, reducing delayed cleaning or malfunctions caused by recognition errors, thereby improving the reliability and self-cleaning efficiency of the entire filtration process.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] In dishwashers, the filter device is used to collect residue in the water flow and prevent blockage during drainage. The filter device usually includes a coarse filter and a fine filter for graded filtration. When there is little residue, the residue will be directly pumped out by the drain pump with the water flow. When there is a lot of residue, the residue is prone to clogging the filter, especially adhering to the surface of the fine filter and gradually accumulating, forming local blockage. Especially when the washing pump continuously circulates water from the water cup to supply water to the spray for washing, the residue will be concentrated and adsorbed on the fine filter near the water inlet of the washing pump under the action of the washing pump, which will affect the filtration efficiency and the return water efficiency of the washing pump, resulting in a reduction in the flow cross-sectional area, an increase in water flow resistance, and affecting the circulation water volume and drainage efficiency.

[0053] Once a persistent layer forms on the surface of the fine filter element, subsequent water flow can only pass through areas with lower resistance, causing local blockage to worsen and even leading to a chain reaction of problems such as filter failure, increased pump load, and reduced cleaning effect.

[0054] In view of this, the slag collection and filtration device and dishwasher provided by the present invention, when the agitator is driven to rotate in the water passage chamber by the drive component, the first cylinder of the agitator will cause the surrounding water to form a circumferential flow and local turbulence, and guide the water flow to the area around the inner filter element, so that the inner filter element is continuously washed by water flow from different directions, thereby achieving the cleaning effect of the inner filter element. Oil stains and fine residues attached to the surface of the inner filter element are more easily removed under the shearing action of the water flow. At the same time, the rotation process can also break the stable accumulation layer of pollutants formed on the inner filter element, causing the residues to be redispersed with the water flow and carried away by the subsequent drainage, thereby solving the problem that the inner filter element is prone to local blockage and affects the water flow.

[0055] The following description, with reference to the accompanying drawings, describes the slag collection and filtration device and dishwasher provided in the embodiments of the present invention.

[0056] refer to Figure 1 and Figure 2As shown, the present invention provides a slag collection and filtration device, including: a water cup 10, a filter assembly 20, and a drive assembly 30. The water cup 10 has a water passage cavity 11; the filter assembly 20 is disposed in the water passage cavity 11, and the filter assembly 20 includes an agitator 21 and an inner filter 22. The agitator 21 is rotatably disposed in the water passage cavity 11, and a receiving cavity 211 is formed inside the agitator 21. At least a portion of the inner filter 22 extends into the receiving cavity 211; the drive assembly 30 is disposed in the water cup 10, and the drive assembly 30 is used to drive the agitator 21 to rotate, so that the agitator 21 agitates the water flow through rotation, thereby rinsing the inner filter 22.

[0057] The present invention provides a slag collection and filtration device. The filtration assembly 20 includes an agitator 21 and an inner filter element 22. The agitator 21 is rotatably disposed within the water passage chamber 11, and a receiving cavity 211 is formed inside the agitator 21. At least a portion of the inner filter element 22 extends into the receiving cavity 211. When the driving assembly 30 drives the agitator 21 to rotate, the agitator 21 causes the surrounding water to form a circumferential flow and local turbulence, guiding the water flow around the inner filter element 22. This allows the inner filter element 22 to be continuously flushed by water flow from different directions, achieving a cleaning effect. Because the inner filter element 22 is located in the turbulent flow area inside the agitator 21, oil stains and fine residues adhering to the surface of the inner filter element 22 are more easily detached under the shearing action of the water flow. Simultaneously, the rotation process breaks up the stable accumulation layer of pollutants formed on the inner filter element 22, causing the residues to redisperse with the water flow and be carried away by subsequent drainage. This solves the problem that the inner filter element 22 is prone to local clogging, affecting water flow and reducing return water efficiency.

[0058] By using the drive assembly 30 to provide continuous or intermittent rotation, the agitator 21 is driven to rotate, which can achieve active cleaning of the inner filter 22 without significantly increasing the complexity of the dishwasher's water circuit. This allows the inner filter 22 to maintain a relatively stable filtration and drainage state even under long-term operation or high pollution load conditions, thereby reducing the pump load, reducing maintenance frequency, and improving the overall cleaning reliability of the machine.

[0059] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, the water passage cavity 11 of the water cup 10 can be cylindrical to facilitate the formation of a stable circulation. The water cup 10 can be made of one or more of food-grade plastic, stainless steel, or corrosion-resistant engineering plastic to meet the requirements for long-term contact with hot water, oil, and cleaning agents.

[0060] The filter assembly 20 is located inside the water passage chamber 11, which can intercept solid residues in the water flow while maintaining the flow capacity.

[0061] In one possible implementation, the agitator 21 can be cylindrical to form a more uniform circumferential flow field. The agitator 21 can also be multi-faceted to enhance the scouring effect through edge turbulence.

[0062] In one possible implementation, the agitator 21 is cylindrical, and the diameter, height, and depth of the accommodating cavity 211 need to be matched according to the space of the water passage cavity 11, the rotational torque, and the filtration area, and the accommodating cavity 211 should be able to accommodate at least part of the inner filter element 22 extending into it.

[0063] In one possible implementation, the surface of the agitator 21 has water flow windows with sufficient permeability to allow a large volume of water to pass through. Alternatively, a filter screen can be installed within the water flow windows to intercept residues in the water flow.

[0064] The inner filter element 22 primarily functions as a filter, filtering the water flowing through the water chamber 11. Large contaminants are collected inside the inner filter element 22, preventing them from entering the dishwasher's drainage system and causing blockages. It also filters and directs small particulate contaminants, completely blocking them within the inner filter element 22 and preventing them from flowing into the circulating washing system, thus avoiding re-spraying contaminants onto the tableware surface. During drainage, small particulate contaminants are directed by the inner filter element 22 to the drain pump and discharged from the dishwasher with the water flow.

[0065] The inner filter element 22 can be a cylindrical structure with mesh holes distributed around its periphery, or it can be a microporous cylindrical structure. The inner filter element 22 is provided with a fine filter screen around its periphery. The material of the inner filter element 22 can be stainless steel wire mesh, plastic filter screen, or composite filter material to meet the requirements of heat resistance, corrosion resistance and easy cleaning.

[0066] In one possible implementation method, refer to Figure 2 and Figure 3 As shown, the inner wall of the agitator 21 is provided with a turbulence structure 40. When the agitator 21 rotates, the turbulence structure 40 guides the water flow to be disturbed, so as to flush the inner filter element 22.

[0067] In one possible implementation, the turbulence structure 40 may be fixedly connected to the inner wall of the agitator 21 so that when the agitator 21 is rotated by the drive assembly 30, the turbulence structure 40 enhances the turbulence effect of the agitator 21 on the water flow.

[0068] In one possible implementation, the turbulence structure 40 can be integrally injection molded plastic structure with the agitator 21, or it can be made of metal sheet, elastic polymer or composite material and fixed to the inner wall of the agitator 21 by welding, bonding, snap-fit ​​or embedding, so as to take into account structural strength, corrosion resistance and processing convenience.

[0069] The turbulence structure 40 is used to change the local flow field distribution in the accommodating cavity 211. As the agitator 21 rotates, the turbulence structure 40 continuously disturbs the water flow in the accommodating cavity 211, causing the water flow to form shearing, entrainment and local impact on the surface and around the inner filter element 22, thereby reducing the possibility of pollutants adhering to the inner filter element 22.

[0070] The water flow that originally flowed smoothly along the inner wall of the accommodating cavity 211 was blocked, diverted and accelerated by the turbulence structure 40 when it passed through it. This caused a local vortex and scouring effect around the inner filter element 22. Since at least part of the inner filter element 22 extends into the accommodating cavity 211, the water flow disturbance guided by the turbulence structure 40 can directly act on the surface of the inner filter element 22 and the vicinity of the filter holes. This makes it easier for fine residues and other pollutants attached to the inner filter element 22 to be peeled off and carried away by the water flow. This reduces the problem of a persistent clogging layer forming on the surface of the inner filter element 22 and improves the self-cleaning ability and long-term reliability of the inner filter element 22.

[0071] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4 As shown, the turbulence structure 40 includes a turbulence plate 41. One side of the turbulence plate 41 is connected to the inner wall of the accommodating cavity 211, and the other side of the turbulence plate 41 extends toward the interior of the accommodating cavity 211 and has a distance H between it and the inner filter element 22, where H > 0.

[0072] In one possible implementation, one side of the baffle 41 is fixedly connected to the inner wall of the accommodating cavity 211. The connection method can be one or more of integral injection molding, welding, or screw fastening. The other side of the baffle 41 extends radially toward the interior of the accommodating cavity 211 to change the water flow path and increase the local flow velocity of the water without affecting the normal rotation of the agitator 21.

[0073] In another possible implementation, one side of the spoiler 41 is detachably connected to the inner wall of the accommodating cavity 211, for example by fasteners such as screws, which facilitates later maintenance and replacement.

[0074] In one possible implementation, the baffle 41 can be any of a flat plate structure, an arc plate structure, a wave plate structure, or a zigzag plate structure. A flat plate structure facilitates processing and assembly, an arc plate structure helps guide the water flow smoothly, a wave plate structure increases the intensity of local disturbance, and a zigzag plate structure can create a multi-directional flow splitting effect within a limited space. The baffle 41 can generate turbulence when the agitator 21 rotates, making it easier for residues adhering to the surface of the inner filter element 22 to detach and be discharged with the water flow.

[0075] There is a gap H, where H > 0, between the other side of the baffle 41 and the inner filter element 22. This is to form an effective water flow channel between the baffle 41 and the inner filter element 22. The water flow within this gap is accelerated and disturbed, effectively cleaning the residue on the surface of the inner filter element 22. The residue is continuously peeled off the surface of the inner filter element 22 and carried away by the water flow. In addition, when the agitator 21 rotates, the existence of this gap can prevent interference and collision between the inner filter element 22 and the baffle 41, thereby ensuring smooth rotation of the agitator 21.

[0076] In one possible implementation, the distance H between the other side of the spoiler 41 and the inner filter 22 can be, for example, 2 mm, 3 mm, 4 mm, 8 mm, 10 mm, etc.

[0077] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4 As shown, the height L1 of the baffle 41 and the height L2 of the agitator 21 satisfy the condition: 0.5 ≤ L1 / L2 ≤ 0.9. This means that the axial coverage of the baffle 41 is neither too small, resulting in insufficient intervention on the water flow, nor too large, thus excessively occupying the internal space of the accommodating cavity 211 and increasing rotational resistance.

[0078] If L1 / L2 < 0.5, the height L1 of the spoiler 41 is too small, reducing the overall disturbance range. If L1 / L2 > 0.9, the fixing strength at the top of the spoiler 41 is weakened, resulting in a decrease in overall strength and service life.

[0079] This application designs the baffle 41 to have sufficient height (0.5≤L1 / L2≤0.9), enabling it to form a sufficiently large water-facing surface during the rotation of the agitator 21. This causes the water entering the receiving cavity 211 to be deflected, entrained, and locally turbulent as it passes through the baffle 41, ensuring its effective agitation of the water flow. This, in turn, promotes the removal of fine residues adhering to the surface of the inner filter element 22, which are then discharged with the water flow. Simultaneously, the height L1 of the baffle 41 is avoided from being too large, which would cause excessive obstruction of the circulating water flow within the water passage cavity 11. This prevents a significant increase in the rotational resistance of the agitator 21, ensuring that the drive assembly 30 maintains a stable workload when driving the agitator 21 to rotate.

[0080] In one possible implementation, L1 / L2 can be, for example, 0.5, 0.6, 0.65, 0.7, 0.8, or 0.9. This balances the turbulence effect with driving efficiency and space requirements, and can be applied to agitators 21 of different specifications.

[0081] Since the agitator 21 and the baffle 41 rotate synchronously, the baffle 41 does not become an independent moving part. Instead, it affects the flow field distribution through the proportional relationship between the height L1 of the baffle 41 and the height L2 of the agitator 21. The water flow forms a pressure difference on the water-facing side and the water-repellent side of the baffle 41, which guides, diverts and agitates the water flow entering the accommodating cavity 211 and its surrounding area. This creates a local flow field that repeatedly scours the inner filter element 22, strengthens the scouring effect on the surface of the inner filter element 22, and improves the continuity of the filtration flow and the anti-clogging performance of the inner filter element 22.

[0082] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the number of baffles 41 can be one, or two, three, or more arranged evenly at intervals along the circumference. The baffles 41 can be any one or a combination of straight plates, curved plates, or bent plates. When the agitator 21 rotates, the baffles 41 have a strong driving effect on the water flow, thereby facilitating the cleaning of accumulated pollutants.

[0083] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, along the height direction of the agitator 21, the baffle 41 is circumferentially twisted along the inner wall of the accommodating cavity 211, and there is a twist angle α between the baffle 41 and the radial plane of the agitator 21, where: 30°≤α≤60°.

[0084] The radial plane of the agitator 21 is the plane perpendicular to the central axis of the agitator 21. Since there is a torsional angle α between the baffle 41 and the radial plane of the agitator 21, the baffle 41 can exert a continuous circumferential deflection on the water flow entering the accommodating cavity 211 when the agitator 21 rotates, and form a compound disturbance between axial propulsion and radial tumbling, so that the water flow repeatedly washes the inner filter 22 to reduce the adhesion and deposition of food residue on the surface of the inner filter 22.

[0085] If the torsion angle α of the spoiler 41 is less than 30°, the disturbance effect may be small, resulting in a reduction in cleaning ability; if the torsion angle α of the spoiler 41 is greater than 60°, the impact will be too large, the torque required for the rotation of the agitator 21 will be too large, the service life of the spoiler 41 will be reduced, the impact on the drive assembly 30 will be large, and the service life of the motor will be reduced.

[0086] In this application, since the torsional angle α between the radial plane of the baffle 41 and the agitator 21 satisfies 30°≤α≤60°, the baffle 41 is able to effectively agitate the water flow, allowing the water flow to repeatedly scour the internal filter 22. This also effectively prevents the baffle 41 from being worn out too much, thus ensuring the service life of the motor.

[0087] In one possible implementation, the torsion angle α of the spoiler 41 can be, for example, 30°, 40°, 45°, 50°, or 60°. This is to ensure that the spoiler 41 generates sufficient turbulence intensity while avoiding excessive rotational resistance of the agitator 21.

[0088] In one possible implementation, the spoiler 41 can be in the form of a single helical blade, a double helical blade, an arc shape, or a crescent shape. The torsion angle of the spoiler 41 can be uniformly and gradually varied along the height direction, or it can adopt a segmented structure to adapt to the scouring requirements of different flow velocities.

[0089] In one possible implementation, the core formula for the hydraulic resistance of the spoiler 41 is:

[0090]

[0091] Wherein: F d The hydraulic resistance of the spoiler 41 is expressed in N.

[0092] ρ is the density of water, which is taken as 1000 kg / m³ for clean water at room temperature;

[0093] A represents the projected area of ​​the spoiler 41 facing the water, in m².

[0094] v is the incoming velocity of the water flow relative to the baffle plate 41, in m / s;

[0095] C is the reference drag coefficient for the vertical incoming flow angle of attack α, which has no unit; the incoming flow angle of attack α is the torsional angle of the spoiler 41.

[0096] The principle of the core formula for hydraulic resistance is that only the normal impact component of the water flow generates effective resistance, while the tangential slip component has no significant resistance loss, and the incoming angle of attack α is corrected for the magnitude of resistance through a sine function.

[0097] In one possible implementation, the spoiler 41 is a concave spoiler, and the reference drag coefficient C for the vertical incoming flow angle of attack α is selected as 1.3, which makes the spoiler 41 have a strong water-catching effect, high drag, strong shear disturbance, and high energy consumption.

[0098] In one possible implementation method, refer to Figure 5 and Figure 6 As shown, the water passage cavity 11 has a first locking part 112, and the bottom of the inner filter element 22 is provided with a second locking part 223. The inner filter element 22 can be rotated and locked into the first locking part 112 in the water passage cavity 11 through the second locking part 223 at the bottom, which facilitates the user to disassemble the inner filter element 22 for cleaning. An additional coarse filter can be added inside the inner filter element 22 to coarsely screen large contaminants.

[0099] At least a portion of the inner filter element 22 extends into the receiving cavity 211. The portion of the inner filter element 22 extending into the receiving cavity 211 is located in the core area of ​​the rotating turbulence of the agitator 21, so that the inner filter element 22 can more fully contact the water flow agitated by the agitator 21. When the agitator 21 rotates, the inner filter element 22 directly receives the scouring force from the water flow agitated by the agitator 21, thereby reducing the problem of the filter holes of the inner filter element 22 being clogged by residue.

[0100] The drive assembly 30 can be located on the outside of the water cup 10. The drive assembly 30 converts external energy into the rotation output of the agitator 21 and causes the agitator 21 to rotate through a transmission connection with the agitator 21.

[0101] By driving the agitator 21 to rotate continuously or intermittently through the drive component 30, the internal filter 22 can be actively cleaned without significantly increasing the complexity of the dishwasher's water circuit. This allows the internal filter 22 to maintain relatively stable filtration and flow performance under long-term operation or high pollution load conditions, thereby reducing the pump load and reducing maintenance frequency.

[0102] In one possible implementation method, refer to Figure 2 and Figure 3 As shown, the agitator 21 has a plurality of first filter holes 214 on its periphery so that the accommodating cavity 211 and the outside of the agitator 21 can be connected through the first filter holes 214.

[0103] The first filter hole 214 is used to establish a fluid communication channel between the accommodating cavity 211 and the outside of the agitator 21, so that the water flow entering the water passage cavity 11 and the turbulent flow generated by agitation can flow through the first filter hole 214, which helps to reduce the accumulation of residue near the inner filter element 22 and improve the flow retention capacity of the filtration process.

[0104] The first filter hole 214 is disposed on the peripheral surface of the agitator 21. The multiple first filter holes 214 can be arranged in an array along the circumferential and height directions of the agitator 21, so that the water flow outside the agitator 21 can continuously enter or exit the accommodating cavity 211 when the agitator 21 rotates.

[0105] In one possible implementation, the first filter hole 214 can be any one or a combination of round holes, elliptical holes, oblong holes, slotted holes, or honeycomb holes. The pore size, pore spacing, and porosity of the first filter hole 214 can be matched and set according to the particle size of the residue particles to be intercepted, the flow rate requirements, and the structural strength of the agitator 21, so as to balance filtration efficiency and flow capacity while meeting the structural strength and rotational stability requirements of the agitator 21.

[0106] Since the agitator 21 has multiple first filter holes 214 on its periphery, and the first filter holes 214 rotate synchronously with the agitator 21, the position of the first filter holes 214 relative to the external water flow of the agitator 21 changes continuously. This creates periodic communication and disturbance exchange on both sides of the first filter holes 214, allowing the external water flow of the agitator 21 to pass through the first filter holes 214 and enter the accommodating cavity 211, and flush the periphery of the inner filter 22, reducing the problem of filter hole clogging in the inner filter 22.

[0107] As the agitator 21 continues to rotate, the relative angles of the multiple first filter holes 214 with the external water flow of the accommodating cavity 211 are constantly changed. The fluid exchange inside and outside the accommodating cavity 211 is continuously enhanced, achieving the self-cleaning effect of the agitator 21. This helps to maintain a stable flow cross-sectional area of ​​the first filter holes 214, improve drainage and filtration efficiency, and reduce the frequency of subsequent manual disassembly and maintenance.

[0108] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 5 As shown, the drive assembly 30 includes a drive member 31 and a transmission unit 32. The drive member 31 is disposed on the outer wall of the water cup 10, and the transmission unit 32 is connected between the drive member 31 and the agitator 21.

[0109] The drive unit 31 converts electrical energy or other external input energy into mechanical rotational motion. The power output by the drive unit 31 is then applied to the agitator 21 via the transmission unit 32 to ensure that the agitator 21 can rotate continuously or intermittently during the filtration process.

[0110] Since the drive component 31 is located on the outer wall of the water cup 10, it can be isolated from the liquid environment inside the water passage cavity 11, thereby preventing the drive component 31 from being damp, immersed in liquid, or contaminated, improving the operational reliability and service life of the drive assembly 30, and also facilitating the installation and maintenance of the drive component 31 from the outside of the water cup 10.

[0111] In one possible implementation, the drive element 31 may be detachably or fixedly connected to the cup 10 by means of screws, clips, or welding.

[0112] In one possible embodiment not shown in the figure, the transmission unit 32 may be a synchronous pulley assembly, which includes two pulleys and a synchronous belt wound around the outside of the two pulleys. The two pulleys are respectively fixed to the output shaft of the drive member 31 and the transmission end at the bottom of the agitator 21. The synchronous belt meshes with the two pulleys to transmit power from the drive member 31 to the agitator 21, thereby driving the agitator 21 to rotate.

[0113] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 5 As shown, the drive unit 31 is a motor, and the drive unit 31 has a drive shaft 311 extending into the water cup 10. The transmission unit 32 includes a drive gear 321 and a driven gear 322. The drive gear 321 is connected to the drive shaft 311. The driven gear 322 is disposed on the outer periphery of the agitator 21, and the driven gear 322 meshes with the drive gear 321.

[0114] In one possible implementation, the motor can be a DC motor, an AC motor, a brushless motor, or a small motor with a gearbox, which can rotate in both directions to better clean the inside of the water chamber 11 and the dead corner area of ​​the inner filter element 22. The drive shaft 311 is the output transmission component of the motor.

[0115] In one possible implementation, the drive gear 321 may be fitted onto the outer periphery of the drive shaft 311, with a flat keyway provided on the outer wall of the drive shaft 311 to facilitate circumferential positioning and circumferential power transmission; the drive gear 321 may also be press-fitted to the outer periphery of the drive shaft 311 with an interference fit, and circumferential power transmission is achieved by relying on the clamping friction force generated by the interference fit.

[0116] In one possible implementation, the driven gear 322 may be integrally formed and connected to the outer periphery of the agitator 21, or it may be fitted onto the outer periphery of the agitator 21. The outer wall of the agitator 21 is provided with a keyway to facilitate circumferential positioning. The outer wall of the agitator 21 also has an axial positioning structure to limit the axial position of the driven gear 322.

[0117] In one possible implementation, the driving gear 321 and the driven gear 322 can be spur gears or helical gears, wherein spur gears are easier to machine and assemble, and helical gears are beneficial for reducing meshing impact and operating noise.

[0118] In one possible implementation, the driving gear 321 and the driven gear 322 are located at the same horizontal level, and the driving gear 321 and the driven gear 322 mesh directly to reduce the transmission chain length and improve transmission stability.

[0119] In one possible implementation, the driven gear 322 is disposed on the outer periphery of the agitator 21 and meshes with the driving gear 321. When the motor is operating, the drive shaft 311 drives the driving gear 321 to rotate, which in turn drives the driven gear 322 to rotate, thus causing the driven gear 322 to rotate the entire agitator 21. This transmission method establishes a stable power transmission link between the motor and the agitator 21, ensuring that the agitator 21 continuously receives rotational driving force within the water passage chamber 11. The rotation of the agitator 21 actively disturbs the water flow around the inner filter element 22, increasing the force of the water flow scouring the inner filter element 22. This reduces the likelihood of residue adhesion and accumulation on the surface of the inner filter element 22, improving its cleaning and flow retention capabilities, reducing the possibility of clogging, and maintaining relatively stable circulating drainage performance of the dishwasher under continuous operating conditions.

[0120] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 5 As shown, the water cup 10 also has a mounting cavity 12, which is located on the side of the water passage cavity 11 and is connected to the water passage cavity 11. The drive gear 321 is located in the mounting cavity 12. The outer wall of the mounting cavity 12 is provided with a clearance hole 121. The drive shaft 311 extends into the mounting cavity 12 through the clearance hole 121. A seal 13 is provided between the drive shaft 311 and the clearance hole 121.

[0121] The mounting cavity 12 is located to the side of the water passage cavity 11 and is interconnected with the water passage cavity 11, so as to separate the drive gear 321 from the area outside the water passage cavity 11, so that the drive gear 321 can work in a relatively dry environment that is easy to assemble and maintain, thereby reducing the impact of water flow or food residue on the transmission unit 32.

[0122] In one possible implementation, the shape of the mounting cavity 12 can be adapted to the shape of the drive gear 321, for example, a cylindrical cavity, to facilitate the housing of the drive gear 321 and prevent the drive gear 321 from being directly exposed to the high-flow scouring environment inside the water passage cavity 11.

[0123] The clearance hole 121 is a through hole opened on the outer wall of the mounting cavity 12. The clearance hole 121 provides a passage for the drive shaft 311 to pass through. The seal 13 is used to fill the mating gap between the drive shaft 311 and the clearance hole 121 to form a waterproof barrier and inhibit water from leaking outward from the clearance hole 121.

[0124] In one possible implementation, the clearance hole 121 is a circular through hole.

[0125] In one possible implementation, the seal 13 can be a rubber sealing ring or a silicone ring. The seal 13 can be installed by press fitting, embedding, snap-fitting, or adhesive bonding. The outer diameter and inner diameter of the seal 13 are respectively set to a slight interference fit or a small clearance fit with the diameter of the clearance hole 121 and the outer diameter of the drive shaft 311, so as to improve the sealing reliability while ensuring smooth rotation of the drive shaft 311 and reducing leakage problems.

[0126] In one possible implementation, the driving gear 321 and the driven gear 322 are located at the same horizontal height, which can be the middle position in the height direction of the agitator 21, in order to reduce the wobble and meshing noise problems of the agitator 21.

[0127] In one possible implementation method, refer to Figure 5 and Figure 6 As shown, the water passage cavity 11 has a first guide portion 111, and the bottom of the agitator 21 has a second guide portion 212 arranged along the circumference of the agitator 21; one of the first guide portion 111 and the second guide portion 212 is a chute, and the other of the first guide portion 111 and the second guide portion 212 is a slide rail. The slide rail is slidably arranged in the chute to guide the circumferential rotation of the agitator 21.

[0128] After assembly, the first guide part 111 and the second guide part 212 form a relative fit along the circumference. The first guide part 111 and the second guide part 212 provide circumferential guidance for the agitator 21, which is used to limit the rotation trajectory of the agitator 21 and improve the rotational stability of the agitator 21. Under the drive of the drive assembly 30, the agitator 21 rotates smoothly along the circumference, reducing the problems of swaying, radial shaking and axial movement of the agitator 21 during rotation, thereby ensuring that the agitator 21 can continuously and stably disturb and flush the water flow around the inner filter 22.

[0129] In one possible implementation, the first guide portion 111 may be disposed on the inner wall of the water passage cavity 11, and the second guide portion 212 is formed on the bottom outer periphery of the agitator 21 and corresponds to the position of the first guide portion 111; the first guide portion 111 may also be disposed on the bottom wall of the water passage cavity 11, and the second guide portion 212 is formed on the bottom of the agitator 21 and rotates synchronously with the agitator 21.

[0130] In one possible implementation, the first guide portion 111 may be an annular groove, and the second guide portion 212 may be a corresponding annular slide rail, with the annular slide rail slidingly fitted within the annular groove to provide continuous guidance during rotation.

[0131] In one possible implementation, the first guide part 111 can be integrally injection molded into the water passage cavity 11, or it can be a separate part connected to the water passage cavity 11 of the water cup 10 by fasteners such as screws.

[0132] In one possible implementation, the second guide portion 212 may be integrally injection molded onto the bottom of the agitator 21. Alternatively, the second guide portion 212 may be a separate part connected to the bottom of the agitator 21 by fasteners such as screws.

[0133] In one possible implementation method, refer to Figure 5 and Figure 7 As shown, the top of the agitator 21 has a third guide portion 213, the top of the inner filter 22 has an outward flange 221, and the lower surface of the outward flange 221 is provided with a fourth guide portion 222. The fourth guide portion 222 and the third guide portion 213 cooperate with each other. One of the fourth guide portion 222 and the third guide portion 213 is a groove, and the other of the fourth guide portion 222 and the third guide portion 213 is a slide rail. The slide rail is slidably disposed in the groove to guide the circumferential rotation of the agitator 21.

[0134] The fourth guide section 222 and the third guide section 213 work together to circumferentially guide the top of the agitator 21, thereby limiting the rotation trajectory of the agitator 21 and improving the rotational stability of the agitator 21. This allows the agitator 21 to rotate smoothly in the circumferential direction under the drive of the drive assembly 30, reducing the problems of swaying, radial shaking and axial movement of the agitator 21 during rotation, and further ensuring that the agitator 21 can continuously and stably disturb and flush the water flow around the inner filter 22.

[0135] In one possible implementation, a fourth guide portion 222 is provided on the lower surface of the outer flange 221. The fourth guide portion 222 is a groove extending circumferentially along the inner filter element 22, and a third guide portion 213 is a slide rail located at the top of the agitator 21 and extending circumferentially along the agitator 21. This provides stable guidance and limiting when the agitator 21 rotates, making the agitator 21 operate more smoothly.

[0136] In one possible implementation method, refer to Figure 2 and Figure 5 As shown, the filter assembly 20 also includes a filter plate 23, which is located above the water cup 10. The filter plate 23 has an installation hole, which corresponds to the water passage cavity 11. The agitator 21 and the inner filter 22 extend into the water passage cavity 11 through the installation hole in the filter plate 23. The outer flange 221 abuts against the inner edge of the installation hole.

[0137] In one possible implementation method, refer to Figure 5 and Figure 9As shown, the slag collection and filtration device also includes an image recognition component 50 and a controller 60, which are electrically connected. The image recognition component 50 is disposed on the inner wall of the water passage chamber 11. The image recognition component 50 is used to collect images of the residue accumulated in the inner filter element 22. When the image recognition component 50 detects that the residue accumulated in the inner filter element 22 has reached a preset amount, it controls the drive component 30 to drive the agitator 21 to rotate.

[0138] The image recognition component 50 visually acquires the state of the residue accumulated inside the inner filter element 22 and outputs the acquired image data to the controller 60 for identification and judgment, so that the device can be driven and controlled according to the actual pollution state rather than a fixed time period.

[0139] The controller 60 determines whether the residue accumulation in the inner filter element 22 has reached a preset amount based on the residue image information fed back by the image recognition component 50, and sends a start signal to the drive component 30 when the condition is met, so as to drive the agitator 21 to rotate and achieve active flushing.

[0140] In one possible implementation, the image recognition component 50 may be positioned close to or above the inner filter 22. The image recognition component 50 may be installed in an embedded manner, with its lens facing the area where the inner filter 22 is located, in order to form a stable field of view and avoid obstruction by the main water flow.

[0141] In one possible implementation, the image recognition component 50 is fixed to the inner wall of the water passage cavity 11 by screws, and a sealing ring is provided at the location of the connecting screws to prevent water leakage in the water passage cavity 11.

[0142] In one possible implementation, the image recognition component 50 includes a camera module, which may be a visible light camera or a miniature industrial camera.

[0143] In another exemplary embodiment, the image recognition component 50 may also employ an infrared imaging module, a multispectral imaging module, or a vision sensor to improve the stability of residue contour recognition in a turbid water vapor environment.

[0144] In one possible implementation, the controller 60 may be a microcontroller or a microprocessor, the specific implementation of which can be selected according to the overall control architecture, and is electrically connected to the image recognition component 50 via wires or a flexible circuit board.

[0145] The preset amount can correspond to the residue coverage area, residue image grayscale change threshold, target area proportion threshold, or residue feature quantity threshold. The controller 60 can perform edge detection, region segmentation, target recognition, or feature comparison on the acquired image based on image recognition algorithms. When it is determined that the degree of residue accumulation in the inner filter element 22 reaches the preset amount, the controller 60 outputs a control command to activate the drive component 30, causing the agitator 21 to rotate. The agitator 21 causes the water flow inside and around the accommodating cavity 211 to be disturbed, thereby continuously flushing and loosening the residue attached to the surface of the inner filter element 22, improving the long-term operational reliability of the filter element 20, and reducing the frequency of subsequent manual disassembly and maintenance.

[0146] Since the self-cleaning control logic of the filter assembly 20 is triggered based on the actual degree of contamination, the agitation action of the agitator 21 can intervene in the residue accumulation process more promptly, preventing residue from adhering to the inner filter assembly 22 for a long time and solidifying on the surface of the inner filter assembly 22. This helps to reduce the problem of filter assembly 20 clogging, maintain the flow capacity of the water passage chamber 11, reduce the resistance of circulating water flow, and reduce the frequency of manual disassembly and cleaning to a certain extent. This improves the operational stability of the filter assembly 20 during long-term use and prevents problems such as increased pump load and affected return water efficiency.

[0147] In one possible implementation method, refer to Figure 5 and Figure 9 As shown, the sludge collection and filtration device also includes an illumination element 70, which is disposed on the inner wall of the water passage chamber 11. The illumination element 70 is electrically connected to the controller 60 and is used to illuminate the image recognition component 50.

[0148] The illumination component 70 provides auxiliary illumination to the interior of the water passage cavity 11, providing stable and uniform illumination conditions for the image recognition component 50 to acquire images of the surface and internal debris of the filter component 20, thereby improving imaging contrast and increasing recognition accuracy.

[0149] The lighting element 70 is installed on the inner wall of the water passage cavity 11. Without occupying the effective volume of the water passage cavity 11, the light emitted by the lighting element 70 covers the shooting area of ​​the inner filter element 22 and the image recognition component 50, and forms a visual monitoring environment in cooperation with the image recognition component 50.

[0150] In one possible implementation, the lighting element 70 may be one or more of the following forms: light-emitting diode (LED) beads, ring light strip, surface light source, point light source, or dimmable light source module, to provide high-brightness, compact lighting conditions.

[0151] The lighting component 70 can be installed by being embedded in the inner wall of the water passage cavity 11 or integrated with the image recognition component 50 as a single module, in order to reduce assembly errors and improve waterproof reliability.

[0152] In one possible implementation, the water cup 10, the stirring element 21, and the inner filter 22 are made of transparent plastic. When the illumination element 70 is on, the image recognition component 50 takes an image. Because the water cup 10, the stirring element 21, and the inner filter 22 are transparent, they appear as bright white spots in the image, while contaminants appear as black patches. Localized accumulations of contaminants appear as large, accumulated black patches. The transparent plastic material effectively improves the accuracy and precision of image recognition.

[0153] The illumination element 70 is continuously lit under the control of the controller 60, or it can be lit on demand or pulsed when the image recognition component 50 enters the acquisition state, to provide optical compensation for the internal area of ​​the water passage chamber 11. When residue adheres to the surface of the inner filter element 22 and causes obstruction or accumulation due to changes in water flow, the image recognition component 50 can acquire a clear image of the residue under the stable illumination provided by the illumination element 70, and determine the amount of residue accumulation accordingly. This allows the controller 60 to more accurately trigger the drive component 30 to work based on the image recognition results of the image recognition component 50, thereby realizing timely monitoring and proactive intervention of the residue accumulation state on the surface of the inner filter element 22, reducing delayed cleaning or malfunctions caused by recognition errors, and thus improving the reliability and self-cleaning efficiency of the entire filtration process.

[0154] The present invention also provides a dishwasher, including the above-described slag collection and filtering device.

[0155] In one possible implementation method, refer to Figure 1 , Figure 5 and Figure 8 As shown, the dishwasher also includes an inner tub 90, which forms a washing chamber inside. A water cup 10 is fixed to the bottom of the inner tub 90. The bottom of the water cup 10 is connected to a washing pump, a water inlet pipe, a drain pipe, a drain pump, and a delivery pipe to form a closed-loop water circuit, ensuring smooth water circulation, water inlet, and water outlet. A spray arm 80 is rotatably installed inside the washing chamber, and a spray hole 81 is opened on the surface of the spray arm 80.

[0156] The washing pump can be connected to the water outlet of the water passage chamber 11. When the dishwasher is working, the washing pump starts to run, draws the stored water in the water passage chamber 11 and pressurizes and delivers it. The high-pressure water flow is delivered to the spray arm 80 through the delivery pipe and then sprayed out from the spray hole 81 on the surface of the spray arm 80. The high-pressure water flow washes away the stains on the inner tank 90 and the surface of the tableware, completing the washing operation.

[0157] In one possible implementation, the surface of the spray arm 80 is also provided with spray holes 82 for cleaning the aforementioned slag collection and filtration device. The spray holes 82 are located on the side of the spray arm 80 facing the aforementioned slag collection and filtration device, so as to perform targeted spray cleaning and slag removal on the aforementioned slag collection and filtration device and improve the cleaning effect.

[0158] In one possible implementation, the spray arm 80 can be water-driven.

[0159] In one possible implementation, the spray arm 80 can also be driven by a motor, so that the spray arm 80 can be stopped at the required position according to the needs of use, and the water flow sprayed from the spray hole 82 can spray the above-mentioned slag collection and filtration device at a fixed point to clean the slag collection and filtration device first.

[0160] The water inlet pipe is installed at the water inlet interface at the bottom of the water cup and connects to an external water source. The water inlet pipe is responsible for automatically filling the water chamber 11 with water. When the dishwasher needs to replenish water, the external water source is smoothly introduced into the water chamber through the water inlet pipe to complete the water storage and replenishment operation, providing sufficient water for subsequent washing water circulation.

[0161] The drain pipe is located at the bottom of the water cup, at a low drain port, serving as a dedicated channel for wastewater discharge. One end of the drain pipe connects to the lowest point of the water passage chamber 11, while the other end extends to the sewer. After washing, the water flows quickly and thoroughly through the drain pipe, preventing wastewater residue from breeding bacteria and producing odors.

[0162] The other structural details of the dishwasher are similar to those in the existing design and will not be described in detail here.

[0163] The dishwasher provided by this invention can improve the self-cleaning ability of the filter structure while realizing normal washing function, reduce the frequency of manual disassembly and washing, and help improve the overall cleaning effect, operational reliability and long-term use stability of the machine.
