Description

Technical Field

[0001] This application relates to the field of air purification technology, and in particular to a purification component and a dishwasher. Background Technology

[0002] As living standards improve, more and more families are equipping their homes with dishwashers to provide a more convenient and comfortable dishwashing experience. However, modern dishwashers offer increasingly sophisticated functions, including not only washing but also powerful drying and storage capabilities. The storage function, which involves storing dishes in a closed space, raises concerns about odor growth and bacterial proliferation, raising safety concerns among users.

[0003] In traditional technologies, air exchange within the storage chamber is primarily achieved through external circulation to ensure air quality. However, this method may introduce external air pollutants, therefore, an air purification function is added in conjunction with external circulation.

[0004] Currently, air purification is mainly achieved through filtration. Although filtration is effective in the early stages of use, it can become saturated with adsorption over time, which may require frequent replacement of consumables, resulting in high operating costs and inconvenience. Utility Model Content

[0005] Therefore, it is necessary to provide a purification component and a dishwasher to address the technical problem of increased operating costs caused by the frequent replacement of consumables in the aforementioned purification components.

[0006] A purification component includes an array dust collection assembly, a spiral dust collection assembly, and a drive fan. The air to be purified is sequentially purified by the array dust collection assembly and the spiral dust collection assembly under the action of the drive fan and then blown out.

[0007] The array dust collection assembly is used to form a first electric field after being powered on, so as to ionize the air to be purified and collect large-particle pollutants therein;

[0008] The spiral dust collection assembly is used to form a magnetic-electric composite field after being energized, so as to collect small-particle pollutants in the air to be purified.

[0009] In one embodiment, the spiral dust collection assembly includes at least one spiral duct;

[0010] A spiral electrode is provided at the center of the spiral duct, and a first spiral plate and a second spiral plate are provided on the inner side wall of the spiral duct. The spiral electrode, the first spiral plate, and the second spiral plate are used to form a second electric field inside the spiral duct.

[0011] The inner wall of the spiral duct is also provided with a first spiral permanent magnet and a second spiral permanent magnet, which are used to form a magnetic field inside the spiral duct.

[0012] The magneto-electric composite field includes the second electric field and the magnetic field.

[0013] In one embodiment, the electric field direction of the second electric field is orthogonal to the magnetic field direction of the magnetic field.

[0014] In one embodiment, the purification component further includes a housing, and the array dust collection assembly, the spiral dust collection assembly, and the drive fan are arranged sequentially inside the housing.

[0015] In one embodiment, the purification component further includes an air guide baffle, the size of which is the same as the radial cross-sectional size of the housing, the air guide baffle is disposed perpendicularly to the axial direction between the array dust collection assembly and the spiral dust collection assembly, and is spaced apart from the array dust collection assembly;

[0016] The air guide baffle has the same number of through holes as the spiral air duct, and each through hole is connected to the inlet of the spiral air duct.

[0017] In one embodiment, the spiral electrode is a spiral tungsten wire electrode, and the first spiral electrode plate and the second spiral electrode plate are spiral metal electrodes.

[0018] In one embodiment, the array dust collection assembly includes an ionizing electrode group and a collecting electrode group, which, when energized, are used to form the first electric field.

[0019] In one embodiment, the collecting electrode group includes at least two collecting electrodes arranged side by side at intervals, and the ionizing electrode group includes at least one ionizing electrode, which is located at the center line position of the two side by side collecting electrodes.

[0020] In one embodiment, the purification component further includes a primary filter element. The air to be purified is sequentially purified by the primary filter element, the array dust collection component, and the spiral dust collection component under the action of the driving fan before being blown out.

[0021] In one embodiment, a dishwasher is provided, the dishwasher including the purification component as described above.

[0022] The aforementioned purification components and dishwasher include an array dust collection assembly, a spiral dust collection assembly, and a drive fan. The air to be purified, under the action of the drive fan, is ionized by the first electric field formed after the array dust collection assembly is energized, turning pollutants into charged particles. Larger particles are then deflected and collected. The spiral dust collection assembly, after being energized, forms a magnetic-electric composite field, which, under the influence of the Lorentz force, causes the pollutants to move in a circular motion in a plane perpendicular to the airflow direction. This significantly extends the residence time of small pollutants within the purification components, increases the trajectory length and deflection probability of smaller pollutants, and improves the overall purification effect. Furthermore, the electro-purification method requires no consumables during use, thus reducing costs and eliminating the need for frequent consumable replacements, making it extremely convenient to use.

[0040] As living standards improve, more and more families are equipping their homes with dishwashers to provide a more convenient and comfortable dishwashing experience. However, modern dishwashers offer increasingly sophisticated functions, including not only washing but also powerful drying and storage capabilities. The storage function, which involves storing dishes in a closed space, raises concerns about odor growth and bacterial proliferation, raising safety concerns for users. Traditionally, air circulation within the storage chamber is used to ensure air quality. However, this method can introduce external air pollutants, necessitating the addition of air purification functions alongside external circulation. Currently, filtration is the primary method for air purification. While filtration is effective initially, it can become saturated over time, requiring frequent replacement of filters, resulting in higher operating costs and inconvenience.

[0041] In one exemplary embodiment, a purification component is provided, such as Figure 1 As shown, the system includes an array dust collection component 100, a spiral dust collection component 200, and a drive fan 300. The air to be purified is blown out after being purified by the array dust collection component 100 and the spiral dust collection component 200 in sequence under the action of the drive fan 300. The array dust collection component 100 is used to form a first electric field after being energized to ionize the air to be purified and collect large-particle pollutants therein. The spiral dust collection component 200 is used to form a magnetic-electric composite field after being energized to collect small-particle pollutants in the air to be purified.

[0042] Specifically, the purification component includes an air inlet side and an air outlet side as shown in the figure. The air to be purified is drawn in from the air inlet side, purified sequentially by the array dust collection assembly 100 and the spiral dust collection assembly 200, and then blown out from the air outlet side. The driving fan 300 is the power device for the air to be purified to flow through the purification component. Its position within the purification component is not fixed; it can be positioned wherever it allows the air to be purified to flow through the dust collection assembly 100 and the spiral dust collection assembly 200. For example, it can be... Figure 1 The dust collection assembly 100 can be located on the air outlet side, or on the air inlet side, or between the dust collection assembly 100 and the spiral dust collection assembly 200.

[0043] Furthermore, the array dust collection assembly 100 is a pre-stage purification device in the purification components. It can be used to form an electric field after being energized to remove most of the large-particle pollutants in the air to be purified, and also has a slight purification effect on small-particle pollutants. The spiral dust collection assembly 200 is a post-stage purification device in the purification components. It can be used to form a magnetic-electric composite field after being energized to further capture and remove the remaining large-particle and small-particle pollutants in the air to be purified.

[0044] The array dust collection component 100 is a purification device formed using the principle of electro-purification. The array dust collection component 100 generally includes an ionization section and a collection section, one connected to a high voltage and the other grounded. Corona discharge is generated between the ionization section and the collection section to form a first electric field. This electrostatic field ionizes particulate pollutants such as dust in the air passing through the ionization section, causing them to become charged and adsorbed onto the collection section, thus achieving the purpose of purifying the air.

[0045] In the above process, due to the limitation of the amount of charge in the electric field generated by the array dust collection component 100, the residence time of charged pollutant particles in the pre-purification device will be short. The deflection effect of the array dust collection component 100 on small-diameter pollutants is small, and they need to be captured by the subsequent post-purification device.

[0046] The spiral dust collection assembly 200 is a purification device that utilizes a magnetic-electric composite field. The spiral dust collection assembly 200 generally includes a magnetic field section and an electric field section. When these two sections are energized, they form a coupled purification zone within the area, where the magnetic and electric fields are coupled. After charged pollutant particles enter the coupled purification zone, they are influenced by the Lorentz force generated by the magnetic field, causing them to move in a circular motion in a plane perpendicular to the airflow direction. Under the influence of the electric field, they are accelerated radially outward along the plane. Thus, the charged pollutant particles actually undergo spiral motion within the spiral dust collection assembly 200. This spiral motion significantly prolongs the residence time of the charged pollutant particles inside the spiral dust collection assembly 200, increases the spatial range covered by the trajectory of the charged pollutant particles, and thus greatly improves the deflection probability of the charged pollutant particles, thereby enhancing the purification effect. This allows for the further capture and removal of both large and small-diameter pollutants remaining in the air to be purified.

[0047] It should be noted that the purification components described in this application, since the array dust collection assembly 100 and the spiral dust collection assembly 200 also involve the capture and collection of pollutant particles, can be cleaned manually or automatically after a certain period of use or at any specified time. After cleaning, the array dust collection assembly 100 and the spiral dust collection assembly 200 can still be reused without the need for consumable replacement. The above-mentioned cleaning process can be implemented in a manner known to those skilled in the art, and will not be elaborated here.

[0048] It is understood that the purification component described in this embodiment can be applied to any scenario where air purification is required, such as the dishwasher mentioned in this application embodiment, or it can be a disinfection device, a drying device, or a purification device, etc.

[0049] The aforementioned purification components include an array dust collection assembly, a spiral dust collection assembly, and a drive fan. Under the action of the drive fan, the air to be purified is ionized by the first electric field formed after the array dust collection assembly is energized, turning the pollutants into charged particles. The larger particles are then deflected and collected. After the spiral dust collection assembly is energized, a magnetic-electric composite field is formed. Under the influence of the Lorentz force, the particles move in a circular motion in a plane perpendicular to the airflow direction, greatly extending their residence time inside the purification components. This increases the trajectory length and deflection probability of small-diameter pollutants, improving the overall purification effect. Furthermore, the electro-purification method requires no consumables during use, thus reducing costs and eliminating the need for frequent replacement of consumables, making it very convenient to use.

[0050] In one exemplary embodiment, such as Figure 2 As shown, the spiral dust collection assembly 200 includes at least one spiral duct 210.

[0051] Specifically, the spiral dust collection assembly 200 is provided with multiple spiral ducts 210 to guide the air to be purified output from the array dust collection assembly 100, so that charged pollutant particles move in a spiral motion within each spiral duct 210. Consequently, the charged pollutant particles are deflected and collected within each spiral duct 210, while other clean air components are blown out normally along the spiral ducts 210, thus achieving the purification of the air to be purified.

[0052] It is understandable that the spiral duct 210 can also serve as a substrate for forming a magnetic-electric composite field, used to fix the electrode plates and magnets that generate the magnetic field and electric field.

[0053] Accordingly, in an exemplary embodiment, please refer to Figure 2 and Figure 3 A spiral electrode 220 is disposed at the center of the spiral duct 210, and a first spiral plate 230 and a second spiral plate 240 are disposed on the inner side wall of the spiral duct 210. The spiral electrode 220, the first spiral plate 230, and the second spiral plate 240 are used to form a second electric field inside the spiral duct 210. A first spiral permanent magnet 250 and a second spiral permanent magnet 260 are also disposed on the inner side wall of the spiral duct 210. The first spiral permanent magnet 250 and the second spiral permanent magnet 260 are used to form a magnetic field inside the spiral duct 210. The magnetic-electric composite field includes the second electric field and the magnetic field.

[0054] Specifically, a spiral electrode 220 is disposed at the center of the spiral duct 210, and a first spiral electrode plate 230 and a second spiral electrode plate 240 are disposed on the inner side wall of the spiral duct 210. Furthermore, when the spiral electrode 220 is connected to high voltage and the first spiral electrode plate 230 and the second spiral electrode plate 240 are grounded, a [structure] can be formed within the spiral duct 210 as follows: Figure 4 As shown in direction A, a second electric field extends from the spiral electrode 220 towards the first spiral plate 230 and the second spiral plate 240, respectively. Under the influence of this second electric field, charged pollution particles will accelerate radially outward along the plane. It is understood that in this embodiment, connecting the spiral electrode 220 to a high voltage and grounding the first spiral plate 230 and the second spiral plate 240 to form an electrostatic field is a convenient method. In other embodiments, the first spiral plate 230 and the second spiral plate 240 can also be connected to a voltage lower than that of the spiral electrode 220, as long as the purpose of forming a second electric field extending from the spiral electrode 220 towards the first spiral plate 230 and the second spiral plate 240, respectively, is achieved.

[0055] The method by which the spiral electrode 220 is fixed to the center of the spiral duct 210 is not unique and can be designed according to actual technical requirements. For example, such as... Figure 5 As shown, in this embodiment, a plurality of triangular support structures 211 are provided at intervals inside the spiral duct 210. The spiral electrode 220 is fixed by each triangular support structure 211 to ensure that the spiral electrode 220 is fixedly set along the center of the spiral duct 210, thereby ensuring the stability of the second electric field strength formed.

[0056] It can be understood that the spiral electrode 220 is a long strip electrode fixed within the spiral duct 210 in a spiral shape. Its cross-section can be designed to be circular to ensure the formation of a relatively uniform second electric field. The electrode material used for the spiral electrode 220 is not unique and can be selected according to actual technical requirements. For example, in an exemplary embodiment, the spiral electrode 220 can be a spiral tungsten wire electrode, or it can be a spiral carbon fiber bundle electrode.

[0057] Secondly, the first spiral electrode plate 230 and the second spiral electrode plate 240 can be attached to the inner wall of the spiral duct 210 with the spiral electrode 220 as the center. (See also...) Figure 3 As shown, the first spiral electrode 230 and the second spiral electrode 240 should have an arc-shaped cross-section to achieve a close fit with the circular inner wall of the spiral duct 210. Exemplarily, the electrode materials used for the first spiral electrode 230 and the second spiral electrode 240 are not unique and can be selected according to actual technical requirements. For example, in an exemplary embodiment, both the first spiral electrode 230 and the second spiral electrode 240 are spiral metal electrodes.

[0058] Furthermore, the inner wall of the spiral duct 210 is also provided with opposing first spiral permanent magnets 250 and second spiral permanent magnets 260. In this application, the explanation is based on the arrangement of the N pole of the first spiral permanent magnet 250 and the S pole of the second spiral permanent magnet 260 facing each other; that is, the N pole of the first spiral permanent magnet 250 faces inwards towards the spiral duct 210, and the S pole of the second spiral permanent magnet 260 faces inwards towards the spiral duct 210. In other embodiments, the S pole of the first spiral permanent magnet 250 and the N pole of the second spiral permanent magnet 260 can also be arranged opposite each other, allowing the air to be purified to move in spiral directions. It should be noted that for the above-mentioned different magnetic pole arrangements, the spiral duct 210 can be designed with matching spiral directions to ensure smooth flow of the air to be purified.

[0059] It is understood that permanent magnets refer to magnets that can retain a high remanence for a long time in an open-circuit state. They have advantages such as being difficult to demagnetize, difficult to be magnetized, high coercivity, high remanence, and good stability. Moreover, with the development of manufacturing technology, the manufacturing cost of permanent magnets has also been reduced, making permanent magnets very suitable as the source of the magnetic field in this application. For example, the permanent magnet materials used in the first helical permanent magnet 250 and the second helical permanent magnet 260 are not limited. They can be rare earth permanent magnet materials (such as neodymium iron boron Nd2Fe14B), samarium cobalt (SmCo), alnico (AlNiCo), etc., selected according to actual needs.

[0060] As charged pollution particles accelerate radially outward along the plane due to the influence of the second electric field, they also experience a Lorentz force exerted by the magnetic field as they cut through the magnetic field lines. The direction of the magnetic field is as follows: Figure 4 As shown in direction B, the direction of the Lorentz force applied from the first helical permanent magnet 250 to the second helical permanent magnet 260 is as follows: Figure 4 As shown in direction C, perpendicularly inwards. Continue referring to... Figure 4 The airflow direction of the air to be purified inside the spiral duct 210 is as shown in direction D, perpendicular to the outside. Furthermore, under the influence of the aforementioned magnetic-electric composite field, charged pollutant particles will be delayed in being blown out, while other clean air components will be blown out normally along the spiral duct 210.

[0061] Subsequently, after the charged pollution particles enter the spiral duct 210, they are affected by the Lorentz force generated by the magnetic field of the first spiral permanent magnet 250 pointing to the second spiral permanent magnet 260, and can make circular motion in a plane perpendicular to the airflow direction. However, under the influence of the second electric field from the spiral electrode 220 pointing to the first spiral plate 230 and the second spiral plate 240 respectively, they will be accelerated radially outward along the plane. Thus, the charged pollution particles will actually make spiral motion within the spiral duct 210, and ultimately... Figure 6The particles are collected on the inner wall of the spiral duct 210. The spiral motion also greatly prolongs the residence time of charged pollution particles inside the spiral duct 210, increases the spatial range covered by the trajectory of charged pollution particles, thereby greatly improving the deflection probability of charged pollution particles and thus improving the purification effect. This allows for the further capture and removal of large-diameter and small-diameter pollutants remaining in the air to be purified.

[0062] It is understood that the spiral electrode 220, the first spiral plate 230, and the second spiral plate 240 are used to form a second electric field inside the spiral duct 210, and the first spiral permanent magnet 250 and the second spiral permanent magnet 260 are used to form a magnetic field inside the spiral duct 210. Thus, the second electric field and the magnetic field can form a magneto-electric composite field within the spiral duct 210. The relationship between the second electric field and the magnetic field in the magneto-electric composite field is not limited, as long as it allows the charged pollution particles to undergo spiral motion within the spiral duct 210. In an exemplary embodiment, the electric field direction of the second electric field is orthogonal to the magnetic field direction of the magnetic field. When the radial airflow direction of the second electric field and the magnetic field direction is perpendicular to each other, it can be ensured that the charged pollution particles are subjected to forces as described above. Figure 7 As shown, in terms of magnetic field force analysis, when the magnetic field moves vertically, the applied Lorentz force is directed inwards along the cross section of the vertical spiral duct 210, thereby effectively increasing the deflection probability of charged pollutant particles and improving the purification effect.

[0063] For example, inside the spiral duct 210, an insulating structure is provided between the first spiral plate 230, the second spiral plate 240, the first spiral permanent magnet 250 and the second spiral permanent magnet 260 to prevent short circuits between them after being energized, which would damage the purification components and affect the normal operation of the purification process.

[0064] In addition, the spiral dust collection assembly 200 can also generate a magnetic field orthogonal to the direction of the second electric field by winding an energized coil around the spiral duct 210. The specific method can be implemented in a way known to those skilled in the art, and will not be elaborated here.

[0065] In one exemplary embodiment, such as Figure 8 As shown, the purification component also includes a housing 400, an array dust collection assembly 100, a spiral dust collection assembly 200 and a drive fan 300 arranged sequentially inside the housing 400.

[0066] Specifically, the housing 400 has an air inlet and an air outlet, and the drive fan 300 can be positioned close to the air outlet. The air to be purified can be drawn in through the air inlet, purified sequentially by the array dust collection assembly 100 and the spiral dust collection assembly 200, and then blown out through the air outlet.

[0067] The material of the housing 400 is not limited and can be selected according to the requirements of the application and performance. For example, it can generally be selected as ABS plastic or galvanized steel plate. The shape and size of the housing 400 are also not limited in this application embodiment and can be designed according to the actual use scenario requirements. For example, it can be designed as a cylindrical shape or a square shape.

[0068] In one exemplary embodiment, such as Figure 2 and Figure 8 As shown, the purification component also includes an air guide baffle 500. The size of the air guide baffle 500 is the same as the radial cross-section of the housing 400. The air guide baffle 400 is vertically arranged between the array dust collection assembly 100 and the spiral dust collection assembly 200, and is spaced apart from the array dust collection assembly 100. The air guide baffle 500 has the same number of through holes 510 as the spiral air duct 210, and each through hole 510 is connected to the inlet of the spiral air duct 210.

[0069] Specifically, since the size of the air guide baffle 500 is the same as the radial cross-section of the housing 400, when the air guide baffle 500 is arranged perpendicular to the axial direction of the housing 400, it can completely block airflow. Furthermore, the air guide baffle 400 is spaced apart from the array dust collection assembly 100, and the air guide baffle 500 is perforated to obtain the same number of through holes 510 as the spiral duct 210, with each through hole 510 corresponding to the inlet of the spiral duct 210. Therefore, the air to be purified output from the array dust collection assembly 100, under the action of the air guide baffle 500, will all pass through the through holes 510 into the spiral duct 210, thus ensuring that all the air to be purified can enter the spiral dust collection assembly 200 for purification.

[0070] Furthermore, the number of through holes 510 can be set according to the number of spiral ducts 210, and the hole diameter is also designed according to the diameter of the spiral duct 210.

[0071] In addition, the size of the gap between the air guide baffle 400 and the array dust collection assembly 100 can be determined according to the amount of circulating air to ensure that the air to be purified can circulate smoothly.

[0072] For example, the air guide baffle 500 can also be designed with a concave shape along the center towards the edge of the housing 400 to guide the air to be purified from the housing 400 to the spiral duct 210 more smoothly, thereby achieving more efficient purification.

[0073] In one exemplary embodiment, such as Figure 8 The array dust collection assembly 100 includes an ionizing electrode group 110 and a collecting electrode group 120. When the ionizing electrode group 110 and the collecting electrode group 120 are energized, they are used to form a first electric field.

[0074] Specifically, the ionizing electrode assembly 110 can be connected to a high voltage, and the collecting electrode assembly 120 can be grounded. A corona discharge is generated between the ionizing electrode assembly 110 and the collecting electrode assembly 120 to form a first electric field. This electrostatic field ionizes particulate pollutants such as dust in the air near the ionizing electrode assembly 110, causing them to become charged and adsorbed onto the surface of the collecting electrode assembly 120, thus purifying the air. It can be understood that grounding the collecting electrode assembly 120 is a convenient way to form the first electric field with the high-voltage ionizing electrode assembly 110. In other embodiments, the collecting electrode assembly 120 can also be connected to a voltage lower than that of the ionizing electrode assembly 110, as long as the purpose of generating a corona discharge and forming the first electric field between the ionizing electrode assembly 110 and the collecting electrode assembly 120 is achieved.

[0075] In one exemplary embodiment, continuing with reference to Figure 8 The collecting electrode group 120 includes at least two collecting electrodes arranged side by side with a gap between them, and the ionizing electrode group 110 includes at least one ionizing electrode, which is located at the center line position of the two collecting electrodes arranged side by side.

[0076] Specifically, the ionizing electrode group 110 may include one or more ionizing electrodes, and the collecting electrode group 120 may include one or more collecting electrodes. When the number of ionizing electrodes in the ionizing electrode group 110 and the number of collecting electrodes in the collecting electrode group 120 are both two or more, the collecting electrodes may be arranged in a row or in a ring, and the arrangement of the ionizing electrodes may be adjusted according to the actual arrangement of the collecting electrodes.

[0077] Furthermore, each collecting electrode assembly 120 includes two or more collecting electrodes arranged side-by-side at intervals, used for adsorbing and precipitating particulate pollutants such as charged dust generated by the ionization of the ionization electrode assembly 110. The shape and size of each collecting electrode are not unique and can be selected according to actual needs. For example, the shape of the collecting electrode can be any one of sheet, triangle, wedge, corrugated, rhombus, teardrop, and fan shape. In this embodiment, sheet or plate-shaped collecting electrodes are selected.

[0078] Furthermore, the ionizing electrode group 110 includes one or more ionizing electrodes. The arrangement of the ionizing electrodes is not unique and can vary depending on the arrangement of the collecting electrodes in the collecting electrode group 120. Taking the collecting electrode group 120 as an example, which includes two or more collecting electrodes arranged side by side with intervals, the ionizing electrodes of the ionizing electrode group 110 are located at the center line of the two side-by-side collecting electrodes. It can be understood that, in this embodiment, the collecting electrodes in the collecting electrode group 120 are arranged side by side with intervals on a plane, and the ionizing electrodes are located at any position on the symmetrical center line of the two side-by-side collecting electrodes. In this embodiment, the number of ionizing electrodes can be one less than the number of collecting electrodes, with one ionizing electrode located on the center line of every two side-by-side collecting electrodes with intervals. In other embodiments, the ionizing electrodes can also be located at any position on both sides of the center line, as long as it is ensured that an electric field can be formed between the ionizing electrodes and the collecting electrodes after energization.

[0079] It is understood that both the array dust collection assembly 100 and the spiral dust collection assembly 200 in this embodiment require power to generate the first electric field and the second electric field. Therefore, the purification component in this embodiment may also include a power supply device. Of course, if the purification component is installed in another main device, such as a dishwasher, the purification component may not include a power supply device and may directly obtain power from the main device.

[0080] For example, the energizing methods of each component in the array dust collection assembly 100 and the spiral dust collection assembly 200 are not unique. Taking an ionizing electrode group containing multiple ionizing electrodes and a collecting electrode group containing multiple collecting electrodes as an example, the energizing method can be that each ionizing electrode and collecting electrode is connected to a corresponding power supply terminal and ground terminal respectively, or they can be connected in series or parallel and then connected to the same power supply terminal and ground terminal. For example, when connected in parallel, each ionizing electrode is connected to the same positive or negative power supply terminal, and each collecting electrode is connected to the same ground terminal, so that multiple ionizing electrodes and collecting electrodes are connected in parallel. When connected in series, the first ionizing electrode arranged side by side at intervals is connected to a positive or negative power supply terminal, and the other ionizing electrodes are connected sequentially; the first collecting electrode arranged side by side at intervals is connected to the ground terminal, and the other collecting electrodes are connected sequentially.

[0081] In one exemplary embodiment, such as Figure 8 As shown, the purification component also includes a primary filter 600. The air to be purified is blown out after passing through the primary filter 600, the array dust collection assembly 100 and the spiral dust collection assembly 200 in sequence under the action of the drive fan 300.

[0082] Specifically, the primary filter element 600 is the primary purification device of the purification component, also known as a pre-filter. It is mainly used to filter dust particles larger than 5μm in the air, capturing large particulate pollutants such as dust and hair from the air entering from the air inlet. The pre-filter can initially block and disperse large particulate pollutants, providing pre-filtration protection for subsequent high-efficiency filtration.

[0083] Furthermore, the primary filter element 600 includes an outer frame and an intermediate filter section. The outer frame can be made of materials such as paper, aluminum, or galvanized iron, offering good robustness and corrosion resistance. The intermediate filter section is primarily made of non-woven fabric, nylon mesh, activated carbon filter media, or metal mesh. Non-woven fabric is one of the most commonly used filter media due to its low resistance, long lifespan, and economic durability. In other embodiments, a protective mesh can be provided in the primary filter element 600, typically double-sided powder-coated wire mesh or double-sided galvanized wire mesh, to enhance the strength of the primary filter element 600 and prevent filter media damage.

[0084] In one exemplary embodiment, a dishwasher is provided, which includes a purification component.

[0085] Specifically, the purification component is mainly equipped with two purification zones, one at the front and one at the back.

[0086] The pre-purification zone is used to remove hair and large-diameter particulate matter, and mainly includes a pre-filter, tungsten wire electrodes, and a rectangular array of dust collection plates. Pollutants first pass through the pre-filter to remove hair and other contaminants. They then enter the first electric field region formed by the tungsten wire electrodes and the rectangular array of dust collection plates. This region charges large-diameter particles, causing them to be collected on the rectangular array of dust collection plates under the influence of the electric field. After purification in this region, most of the large-particle pollutants are removed. The remaining air still contains some large-particle pollutants and a large proportion of small-particle pollutants. The small-particle pollutants cannot be deflected and collected due to insufficient charge and charging time in the first electric field.

[0087] Secondly, the area to be purified after treatment in the pre-purification zone enters the post-purification zone, which powerfully captures large-particle pollutants. This mainly includes a dust collection structure formed by a spiral duct. A spiral electrode is located at the center of the spiral duct, and opposing first and second spiral plates are arranged on the inner wall of the spiral duct. The spiral electrode, the first spiral plate, and the second spiral plate are used to form a second electric field inside the spiral duct. Opposing first and second spiral permanent magnets are also arranged on the inner wall of the spiral duct, which are used to form a magnetic field inside the spiral duct. The radial components of the second electric field and the magnetic field are perpendicular to each other, forming a magnetic-electric composite purification field.

[0088] Subsequently, after the charged pollution particles enter the spiral duct, they are influenced by the Lorentz force generated by the magnetic field of the first spiral permanent magnet pointing towards the second spiral permanent magnet. This causes them to undergo circular motion in a plane perpendicular to the airflow direction. Furthermore, influenced by the second electric field pointing from the spiral electrodes towards the first and second spiral plates respectively, they are accelerated radially outwards along the plane. Thus, the charged pollution particles actually undergo spiral motion within the spiral duct and are eventually collected on the inner wall of the duct. This spiral motion significantly prolongs the residence time of the charged pollution particles inside the spiral duct and increases the spatial range covered by their trajectory, thereby greatly improving the deflection probability of the particles and enhancing the purification effect. This allows for the further capture and removal of both large and small-diameter pollutants remaining in the air to be purified.

[0089] At the same time, when passing through a long deflection distance path, the ionized high-energy active particles can also kill bacteria carried by the airflow to be purified.

[0090] In the above embodiments, by constructing the novel spiral strong pollutant capture zone, and combining the whole machine with the partitioned purification of large and small particulate pollutants, the shortcomings of traditional electro-purification and filtration are avoided. At the same time, high purification and sterilization efficiency and no consumables are achieved, realizing efficient external circulation purification and sterilization of the dishwasher storage.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
