DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] With the improvement of living standards, more and more families are equipped with dishwashers to provide a more convenient and comfortable dishwashing experience. However, the current dishwashers are becoming more and more functional. They can not only wash dishes, but also have powerful drying and storage functions. The storage function, because the dishes are stored in a confined space, has attracted much attention from users for safety issues such as odor breeding and bacterial reproduction. In traditional technology, the air in the storage cavity is generally ventilated through external circulation to ensure the air quality in the storage cavity. However, this method may also introduce external air pollutants, so the air purification function will be added while the external circulation is in place. At present, air purification is mainly carried out through filtering. Although the filtering type is effective in the early stage of use, it will lead to adsorption saturation as the use time increases, and consumables may need to be replaced frequently, which is costly and inconvenient to use.

[0041] In an exemplary embodiment, a purification component is provided, such as Figure 1 As shown, it includes an array dust collecting component 100, a spiral dust collecting component 200 and a driving fan 300. Under the action of the driving fan 300, the air to be purified is sequentially purified through the array dust collecting component 100 and the spiral dust collecting component 200 and then blown out; the array dust collecting 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 collecting 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 can be sucked in from the air inlet side, and then blown out from the air outlet side after being purified by the array dust collecting component 100 and the spiral dust collecting component 200 in sequence. Among them, the driving fan 300 is a power device for the air to be purified to flow through the purification component. The position where it can be set in the purification component is not fixed. As long as it can make the air to be purified flow through the dust collecting component 100 and the spiral dust collecting component 200, it can be any position, such as Figure 1 As shown, it is arranged on the air outlet side, and it can also be arranged on the air inlet side, or it can be arranged at a position between the dust collecting component 100 and the spiral dust collecting component 200.

[0043] Furthermore, the array dust collection assembly 100 is a pre-stage purification device in the purification component, which can be used to form an electric field after being powered on 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 component, which can be used to form a magnetic-electric composite field after being powered on to further capture and remove the remaining large-particle pollutants and small-particle pollutants in the air to be purified.

[0044] The array dust collection assembly 100 is a purification device formed by using the principle of electric purification. The array dust collection assembly 100 generally includes an ionization part and a collection part, one part is connected to high voltage, and the other part is grounded. Then, corona discharge is generated between the ionization part and the collection part to form a first electric field, and the electrostatic field is used to ionize dust and other particulate pollutants in the air passing through the ionization part, so that the dust is charged and adsorbed to the collection part, thereby achieving the purpose of purifying the air.

[0045] In the above process, due to the limitation of the amount of charge generated by the electric field of the array dust collecting component 100, the residence time of the charged polluted particles in the front-stage purification device will be shorter, and the deflection effect of the array dust collecting component 100 on small-particle pollutants is smaller, which needs to be captured by subsequent rear-stage purification devices.

[0046] The spiral dust collecting assembly 200 is a purification device formed by using a magnetic-electric composite field. The spiral dust collecting assembly 200 generally includes a magnetic field part and an electric field part. When the two parts are energized, a coupled purification zone in which the magnetic field and the electric field are coupled can be formed in the region. After the charged polluted particles enter the coupled purification zone, they are affected by the Lorentz force generated by the magnetic field and can make circular motion in a plane perpendicular to the airflow direction, while they are affected by the electric field and are accelerated radially outward along the plane, so that the charged polluted particles actually make spiral motion in the spiral dust collecting assembly 200. The spiral motion also greatly prolongs the residence time of the charged polluted particles inside the spiral dust collecting assembly 200, increases the spatial range covered by the motion trajectory of the charged polluted particles, thereby greatly increasing the deflection probability of the charged polluted particles, and thus improving the purification effect, so that the remaining large-particle-size pollutants and small-particle-size pollutants in the air to be purified can be further captured and removed.

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

[0048] It can be 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 the embodiment of the present application, or it can be a disinfection device, a drying device, a purification device, etc.

[0049] The above-mentioned purification component includes an array dust collection component, a spiral dust collection component and a driving fan. Under the action of the driving fan, the air to be purified is ionized by the first electric field formed after the array dust collection component is powered on, so that the pollutants therein become charged particles, and the large-particle pollutants therein are deflected and collected. After the spiral dust collection component is powered on, a magnetic-electric composite field is formed, and under the influence of the Lorentz force, it moves in a circle in a plane perpendicular to the airflow direction, which greatly prolongs its residence time inside the purification component, increases the movement trajectory length and deflection probability of small-particle pollutants, and improves the overall purification effect. In addition, the electric purification method has no consumables at all during use, thereby reducing costs and eliminating the need for frequent replacement of consumables, making it very convenient to use.

[0050] In an exemplary embodiment, Figure 2 As shown, the spiral dust collecting assembly 200 includes at least one spiral air duct 210 .

[0051] Specifically, a plurality of spiral air ducts 210 are provided in the spiral dust collecting assembly 200, which are used to guide the air to be purified output from the array dust collecting assembly 100, so that the charged polluted particles make spiral motion in each spiral air duct 210. Then, the charged polluted particles are deflected and collected in each spiral air duct 210, and other clean air components are blown out normally along the spiral air duct 210, thereby purifying the air to be purified.

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

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

[0054] Specifically, a spiral electrode 220 is disposed at the center of the spiral air duct 210, and a first spiral electrode plate 230 and a second spiral electrode plate 240 are disposed opposite to each other on the inner side wall of the spiral air duct 210. When the spiral electrode 220 is connected to a high voltage and the first spiral electrode plate 230 and the second spiral electrode plate 240 are grounded, a voltage such as Figure 4 As shown in the direction A, the second electric field from the spiral electrode 220 points to the first spiral pole plate 230 and the second spiral pole plate 240 respectively. Under the influence of the second electric field, the charged polluted particles will be accelerated radially outward along the plane. It can be understood that the spiral electrode 220 described in this embodiment is connected to high voltage, and the first spiral pole plate 230 and the second spiral pole plate 240 are grounded to form an electrostatic field. This is a more convenient way. In other embodiments, the first spiral pole plate 230 and the second spiral pole plate 240 can also be connected to a voltage lower than the voltage of the spiral electrode 220, as long as the purpose of forming a second electric field from the spiral electrode 220 to the first spiral pole plate 230 and the second spiral pole plate 240 can be achieved.

[0055] There is no unique way to fix the spiral electrode 220 to the center of the spiral air duct 210, and it can be designed according to actual technical requirements. Figure 5 As shown, in this embodiment, a plurality of triangular support structures 211 are arranged at intervals in the spiral air duct 210, and the spiral electrode 220 is fixed by each triangular support structure 211 to ensure that the spiral electrode 220 is fixedly arranged along the center of the spiral air duct 210, thereby ensuring the stability of the intensity of the second electric field formed.

[0056] It can be understood that the spiral electrode 220 is a long strip electrode that is fixed in a spiral in the spiral air duct 210, and 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 metal tungsten wire electrode, or the spiral electrode 220 can also be a spiral carbon fiber bundle electrode.

[0057] Secondly, the first spiral electrode plate 230 and the second spiral electrode plate 240 can be relatively attached to the inner wall of the spiral air duct 210 with the spiral electrode 220 as the center. Figure 3 As shown, the first spiral electrode plate 230 and the second spiral electrode plate 240 should be designed in an arc shape in cross section to achieve fitting with the circular inner wall of the spiral air duct 210. For example, the electrode materials used for the first spiral electrode plate 230 and the second spiral electrode plate 240 are not unique and can be selected according to actual technical requirements. For example, in an exemplary embodiment, the first spiral electrode plate 230 and the second spiral electrode plate 240 are both spiral metal electrodes.

[0058] Further, the inner side wall of the spiral air duct 210 is also provided with a relative first spiral permanent magnet 250 and a second spiral permanent magnet 260. Among them, the present application is explained in a manner that the N pole of the first spiral permanent magnet 250 and the S pole of the second spiral permanent magnet 260 are relatively arranged, that is, the N pole of the first spiral permanent magnet 250 is arranged toward the inside of the spiral air duct 210, and the S pole of the second spiral permanent magnet 260 is arranged toward the inside of the spiral air duct 210. In other embodiments, of course, 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 relative to each other, so that the air to be purified performs spiral motion in different directions. It should be noted that for the above-mentioned different magnetic pole settings, the spiral air duct 210 can be designed to match the spiral direction to ensure the smooth circulation of the air to be purified.

[0059] It can be understood that a permanent magnet refers to a magnet that can retain a high remanence for a long time in an open circuit state, and has the advantages of not easy to lose magnetism, not easy to be magnetized, high coercive force, high remanence and good stability. With the development of manufacturing technology, the manufacturing cost of permanent magnets has also been reduced, and it is very appropriate to use permanent magnets as the source of the magnetic field of this application. Exemplarily, the permanent magnet material used by the first spiral permanent magnet 250 and the second spiral permanent magnet 260 is not limited, and can be a rare earth permanent magnet material (such as neodymium iron boron Nd2Fe14B), samarium cobalt (SmCo), aluminum nickel cobalt (AlNiCo), etc., which can be selected according to actual needs.

[0060] When the charged polluted particles are accelerated radially outward along the plane due to the influence of the second electric field, they will also be affected by the Lorentz force exerted by the magnetic field due to cutting the magnetic field lines. The direction of the magnetic field is as follows: Figure 4 As shown in the B direction, the direction of the Lorentz force applied is from the first spiral permanent magnet 250 to the second spiral permanent magnet 260. Figure 4 As shown in the direction of C in the middle, it is vertically inward. Figure 4 , the airflow direction of the air to be purified in the spiral air duct 210 is shown as direction D, which is vertically outward. Further, under the influence of the magnetic-electric composite field, the charged polluted particles will be delayed from being blown out, while other clean air components will be blown out along the spiral air duct 210 normally.

[0061] After the charged polluted particles enter the spiral air 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, they are affected by the second electric field pointing from the spiral electrode 220 to the first spiral pole plate 230 and the second spiral pole plate 240 respectively, and are accelerated radially outward along the plane. As a result, the charged polluted particles actually make spiral motion in the spiral air duct 210, and finally Figure 6As shown, the charged pollutants are collected on the inner wall of the spiral air duct 210. The spiral motion also greatly prolongs the retention time of the charged pollutants in the spiral air duct 210, increases the spatial range covered by the movement trajectory of the charged pollutants, thereby greatly improving the deflection probability of the charged pollutants, thereby improving the purification effect, so that the remaining large-particle-size pollutants and small-particle-size pollutants in the air to be purified can be further captured and removed.

[0062] It can be understood that the spiral electrode 220 and the first spiral pole plate 230 and the second spiral pole plate 240 are used to form a second electric field inside the spiral air 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 air duct 210, and then the second electric field and the magnetic field can form a magnetic-electric composite field inside the spiral air duct 210. The relationship between the second electric field and the magnetic field in the magnetic-electric composite field is not limited, as long as the charged pollution particles can make a spiral motion in the spiral air 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 air volume of the electric field direction of the second electric field and the magnetic field direction of the magnetic field are perpendicular to each other, it can be ensured that the charged pollution particles are subjected to a force such as Figure 7 As shown, for the magnetic field force analysis, when the vertical magnetic field moves, the Lorentz force applied is perpendicular to the cross section of the spiral air duct 210 and inward, thereby effectively increasing the deflection probability of charged polluted particles and improving the purification effect.

[0063] Exemplarily, inside the spiral air duct 210, an insulating structure is provided between the first spiral pole plate 230, the second spiral pole plate 240, the first spiral permanent magnet 250 and the second spiral permanent magnet 260 to prevent short circuits between them after being energized and damage to purification components, thereby affecting 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 electric field direction of the second electric field by winding an energized coil outside the spiral air duct 210. The specific method can be implemented according to methods known to technicians in this field and will not be elaborated on.

[0065] In an exemplary embodiment, Figure 8 As shown, the purification component also includes a shell 400, and the array dust collecting component 100, the spiral dust collecting component 200 and the driving fan 300 are arranged in sequence inside the shell 400.

[0066] Specifically, the housing 400 is provided with an air inlet and an air outlet, and the driving fan 300 can be arranged near the air outlet. The air to be purified can be sucked in from the air inlet, and after being purified by the array dust collection assembly 100 and the spiral dust collection assembly 200 in sequence, it is blown out from 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, ABS plastic and galvanized steel plate can be selected. The shape and size of the housing 400 are not limited in the embodiment of the present application and can be designed according to the actual use scenario requirements. For example, it can be designed to be cylindrical or square.

[0068] In an exemplary embodiment, 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 consistent with the radial cross-sectional size of the shell 400, the air guide baffle 400 is vertically axially arranged between the array dust collecting component 100 and the spiral dust collecting component 200, and is arranged with a gap from the array dust collecting component 100; the air guide baffle 500 is provided with through holes 510 with the same number as the spiral air duct 210, and each through hole 510 is correspondingly connected to the inlet of the spiral air duct 210.

[0069] Specifically, since the size of the air guide baffle 500 is consistent with the radial cross-section size of the shell 400, when the air guide baffle 500 is set perpendicular to the axial direction of the shell 400, the air circulation can be completely blocked. Further, the air guide baffle 400 and the array dust collection assembly 100 are set with a gap, and the air guide baffle 500 is opened at the same time to obtain the same number of through holes 510 as the spiral air duct 210, and each through hole 510 is connected to the entrance of the spiral air duct 210. Then, the air to be purified output from the array dust collection assembly 100 will enter the spiral air duct 210 through the through holes 510 under the action of the air guide baffle 500, thereby ensuring that all the air to be purified can enter the spiral dust collection assembly 200 for purification.

[0070] Furthermore, the number of the through holes 510 can be set according to the number of the spiral air ducts 210 , and the hole size is also designed according to the diameter of the spiral air ducts 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 circulating air volume to ensure that the air to be purified can circulate smoothly.

[0072] Exemplarily, the air guide baffle 500 may also be designed to be concave along the center toward the edge of the shell 400, so as to more smoothly guide the air to be purified from the shell 400 to the spiral air duct 210, thereby achieving more efficient purification.

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

[0074] Specifically, the ionization electrode group 110 may be connected to a high voltage, the collector group 120 may be grounded, a corona discharge may be generated between the ionization electrode group 110 and the collector group 120 to form a first electric field, and the dust and other particulate pollutants in the air near the ionization electrode group 110 may be ionized by the electrostatic field, so that the dust and other particulate pollutants in the air near the ionization electrode group 110 are charged and adsorbed on the surface of the collector group 120, thereby achieving the purpose of purifying the air. It can be understood that the collector group 120 is grounded as a more convenient way to form the first electric field with the ionization electrode group 110 connected to a high voltage. In other embodiments, the collector group 120 may also be connected to a voltage lower than the voltage of the ionization electrode group 110, as long as the purpose of generating a corona discharge between the ionization electrode group 110 and the collector group 120 to form the first electric field can be achieved.

[0075] In an exemplary embodiment, referring to Figure 8 The collecting electrode group 120 includes at least two collecting electrodes arranged side by side and spaced apart from each other, and the ionizing electrode group 110 includes at least one ionizing electrode, which is arranged at the center line position of the two collecting electrodes arranged side by side.

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

[0077] Furthermore, each collecting electrode group 120 includes two or more collecting electrodes arranged side by side and spaced apart, which are used to adsorb and precipitate charged dust and other particulate pollutants generated by ionization of the ionizing electrode group 110. The shape and size of each collecting electrode are not unique and can be selected according to actual needs. Exemplarily, the shape of the collecting electrode is any one of a sheet, a triangle, a wedge, a corrugated shape, a diamond, a water drop shape and a fan shape. In the embodiment of the present application, a sheet or plate-shaped collecting electrode is selected.

[0078] Furthermore, the ionization electrode group 110 includes one or more ionization electrodes, and the arrangement of the ionization electrodes is not unique, and can be changed according to the different arrangements of the collector electrodes in the collector electrode group 120. Taking the collector electrode group 120 including two or more collector electrodes arranged side by side and spaced as an example, the ionization electrode of the ionization electrode group 110 is arranged at the center line position of the two collector electrodes arranged side by side. It can be understood that in this embodiment, the collector electrodes in the collector electrode group 120 are arranged side by side and spaced on a plane, and the ionization electrode is arranged at any position on the symmetrical center line of the two collector electrodes arranged side by side. Under the arrangement of this embodiment, the number of ionization electrodes can be one less than the number of collector electrodes, and an ionization electrode is arranged on the center line of every two collector electrodes arranged side by side and spaced. In other embodiments, the ionization electrode can also be arranged at any position on both sides of the center line, as long as it is ensured that the ionization electrode and the collector electrode can form an electric field after power is turned on.

[0079] It can be understood that the array dust collection component 100 and the spiral dust collection component 200 of this embodiment need to be powered on to generate the first electric field and the second electric field, and the purification component of the embodiment of the present application may also include a power supply device. Of course, when the purification component is set in another main device, for example, when the purification component is set in a dishwasher, the purification component may not include a power supply device and directly obtain power from the main device.

[0080] And among them, illustratively, the way that each component in the array dust collection component 100 and the spiral dust collection component 200 is powered is not unique. Taking the ionization electrode group including multiple ionization electrodes and the collecting electrode group of multiple collecting electrodes as examples, the power-on method can be that each ionization electrode and the collecting electrode are respectively connected to a corresponding power terminal and ground terminal, or it can be connected to the same power terminal and ground terminal after being connected in series or in parallel. For example, when connected in parallel, each ionization electrode is connected to the same positive or negative power terminal, and each collecting electrode is connected to the same ground terminal, so that multiple ionization electrodes are connected in parallel with the collecting electrode. When connected in series, the first ionization electrode arranged side by side and spaced apart is connected to a positive or negative power terminal, and the other ionization electrodes are connected in sequence; the first collecting electrode arranged side by side and spaced apart is connected to the ground terminal, and the other collecting electrodes are connected in sequence.

[0081] In an exemplary embodiment, Figure 8 As shown, the purification component also includes a primary filter element 600. Under the action of the driving fan 300, the air to be purified passes through the primary filter element 600, the array dust collection component 100 and the spiral dust collection component 200 in sequence and is then blown out after being purified.

[0082] Specifically, the primary filter device 600 is a primary purification device of the purification component, which can also be called a primary filter, and is mainly used to filter dust particles larger than 5 μm in the air, that is, to capture large particle pollutants such as dust and hair in the air to be purified that enters from the air inlet. The primary filter can initially block and disperse large particle pollutants, providing pre-filtration protection for subsequent high-efficiency filtration.

[0083] Furthermore, the primary filter device 600 includes an outer frame portion and an intermediate filter portion. The outer frame portion can be made of, for example, a paper frame, an aluminum frame, a galvanized iron frame, etc., and has good firmness and corrosion resistance. The intermediate filter portion can be mainly made of non-woven fabrics, nylon meshes, activated carbon filter materials, and metal meshes. Among them, non-woven fabrics are one of the most commonly used filter materials because they have the characteristics of low resistance, long life, and economic durability. In other embodiments, a protective net can also be provided in the primary filter device 600, which can usually be a double-sided plastic-sprayed wire mesh and a double-sided galvanized wire mesh to enhance the strength of the primary filter device 600 and prevent the filter material from being damaged.

[0084] In one exemplary embodiment, a dishwasher is provided, the dishwasher including a purification component.

[0085] Specifically, the purification component is mainly provided with two front and rear purification areas.

[0086] Among them, the pre-purification area is used to remove hair and large-sized particles, and mainly includes a primary filter, a metal tungsten wire electrode and a rectangular array dust collecting plate. The pollutants first pass through the primary filter to remove pollutants such as hair. Then they enter the first electric field area formed by the metal tungsten wire electrode and the rectangular array dust collecting plate. This area can charge large-sized particles so that they can be collected on the rectangular array dust collecting plate under the action of the electric field force. After purification in this area, most of the large particle pollutants are removed, and the air to be purified still contains some large particle pollutants and the vast majority of small particle pollutants. The small particle pollutants cannot be deflected and collected due to insufficient charge and charging time of the first electric field.

[0087] Secondly, the area to be purified after the treatment in the pre-purification area enters the post-purification area to capture large-particle pollutants with great force. It mainly includes a dust collecting structure formed by a spiral air duct. A spiral electrode is arranged at the center of the spiral air duct. The inner wall of the spiral air duct is provided with a first spiral pole plate and a second spiral pole plate opposite to each other. The spiral electrode and the first spiral pole plate and the second spiral pole plate are used to form a second electric field inside the spiral air duct. The inner wall of the spiral air duct is also provided with a first spiral permanent magnet and a second spiral permanent magnet opposite to each other. The first spiral permanent magnet and the second spiral permanent magnet are used to form a magnetic field inside the spiral air duct. Among them, the radial components of the second electric field and the magnetic field are perpendicular to each other to form a magnetic-electric composite purification field.

[0088] After the charged polluted particles enter the spiral air duct, they are affected by the Lorentz force generated by the magnetic field of the first spiral permanent magnet pointing to the second spiral permanent magnet, and can make circular motion in a plane perpendicular to the airflow direction. Under the influence of the second electric field pointing from the spiral electrode to the first spiral pole plate and the second spiral pole plate, they will be accelerated radially outward along the plane, and the charged polluted particles will actually make spiral motion in the spiral air duct and finally be collected on the inner wall of the spiral air duct. The spiral motion also greatly prolongs the retention time of the charged polluted particles inside the spiral air duct, increases the spatial range covered by the movement trajectory of the charged polluted particles, and thus greatly increases the deflection probability of the charged polluted particles, thereby improving the purification effect, so that the remaining large-particle pollutants and small-particle pollutants in the air to be purified can be further captured and removed.

[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 air flow to be purified.

[0090] In the above embodiment, by constructing the above-mentioned new spiral strong pollutant capture zone, and at the same time combining the whole machine with the zoning purification of large and small particles of pollutants, the respective shortcomings of traditional electric purification and filtration are avoided, while achieving high purification and sterilization efficiency and no consumables, thereby realizing efficient external circulation purification and sterilization of dishwasher storage.

[0091] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
