The utility model provides an electrostatic precipitator module and air treatment device.

The electrostatic dust removal module is applied to an air treatment device to improve the quality of air. The air treatment device is a device capable of adjusting the temperature, humidity or cleanliness of air, and includes but is not limited to fans, indoor air conditioners, air purifiers and air humidifiers. The indoor unit of the air conditioner comprises but is not limited to a floor type indoor unit of the air conditioner, a vertical hanging unit and a wall-mounted indoor unit of the air conditioner.

Specifically, the air treatment device comprises a shell, the shell is provided with an air inlet, an air outlet and an air treatment air channel between the air inlet and the air outlet, and the electrostatic dust removal module is usually arranged at the air inlet to remove particle pollutants in the air so as to enable cleaner air to enter the shell; of course, the electrostatic dust removal module can also be arranged in the air treatment duct or at the air outlet.

In an embodiment of the present invention, as shown in fig. 1-4, the electrostatic dust collection module 100 includes a dust collection unit 10, and the dust collection unit 10 includes:

the first electrode 11 comprises a first sub-electrode 111 and a second sub-electrode 112 which are sequentially arranged in the air inlet direction;

the second electrode 12 is arranged on the first side of the first electrode 11, and a charging electric field is formed between the second electrode 12 and the first sub-electrode 111;

the third electrode 13 is arranged on the first side of the first electrode 11, and the third electrode 13 and the second electrode 12 are sequentially arranged in the air inlet direction; and

and the additional electrode 17 is arranged between the second sub-electrode 112 and the third electrode 13, and the additional electrode 17 enables at least two dust collecting electric fields to be formed between the second sub-electrode 112 and the third electrode 13.

Specifically, the second electrode 12 is disposed on a first side of the first electrode 11, and the third electrode 13 is disposed on the first side of the first electrode 11, that is, the second electrode 12 and the third electrode 13 are both disposed on the same side of the first electrode 11.

Optionally, the second electrode 12 is disposed corresponding to the first sub-electrode 111, and the third electrode 13 is disposed corresponding to the second sub-electrode 112.

It can be understood that the charged electric field and the at least two dust collecting electric fields are arranged in sequence in the air inlet direction, and the flowing air passes through the charged electric field and the at least two dust collecting electric fields in sequence. Wherein, when the flowing air passes through the charged electric field, the particle pollutants (such as dust particles) in the air can be charged to become charged particle pollutants; then the flowing air respectively enters at least two dust collecting electric fields.

It will be appreciated that each collecting field has a collector and a repeller for repelling charged particulate contaminants towards the collector; the collector is used for forming a dust collecting electric field with the repeller and is used for collecting charged particle pollutants. Wherein the repeller and collector can be determined by the electrical properties of the first electrode 11, the second electrode 12, the third electrode 13 and the additional electrode 17, which will be described in detail below.

After entering the dust collecting electric field, the flowing air moves towards the collector under the action of the repeller, so that the charged particle pollutants are adsorbed/collected on the collector, and the electrostatic dust collection effect is achieved.

The utility model discloses electrostatic precipitator module 100 is through addding additional electrode 17 between second sub-electrode 112 and third electrode 13 to form two at least collection dirt electric fields between second sub-electrode 112 and third electrode 13, on the one hand, can improve the utilization ratio of the lotus electric field of single dust removal unit 10, thereby can improve the electrostatic precipitation effect. On the other hand, the number of the first electrode 11 and the second electrode 12 of the electrostatic dust removal module 100 can be reduced, thereby reducing the manufacturing cost; in particular, when the second electrode 12 is a wire-like structure, the difficulty of assembly can also be reduced.

In a specific embodiment, the first sub-electrode 111 and the second sub-electrode 112 may be separately disposed at intervals, or may be integrally disposed.

In the present invention, as shown in fig. 4, the first sub-electrode 111 and the second sub-electrode 112 are integrally disposed, and it can be understood that the first sub-electrode 111 is a first sub-electrode 111 segment of the first electrode 11, and the second sub-electrode 112 is a second sub-electrode 112 segment of the first electrode 11. Thus, the first electrode 11 can be shared to form a charged electric field and a dust collecting electric field, so that the first electrode 11 can not only charge the particle pollutants, but also collect the charged particle pollutants, thereby not only effectively simplifying the structure of the electrostatic dust removal module 100 (such as simplifying a circuit and the like), and reducing the manufacturing difficulty of the electrostatic dust removal module 100; it is also advantageous to reduce the overall thickness of the electrostatic precipitation module 100, thereby facilitating the realization of a miniaturized design of the electrostatic precipitation module 100.

The following will describe the electrostatic precipitator module 100 in detail by taking an example of the first sub-electrode 111 and the second sub-electrode 112 being integrally disposed, and on this basis, those skilled in the art will easily think of the structure of the electrostatic precipitator module 100 when the first sub-electrode 111 and the second sub-electrode 112 are separately disposed at intervals.

In an embodiment, the number of the additional electrodes 17 can be any value greater than or equal to 1, and it is only necessary to adjust the electrical properties of the first electrode 11, the second electrode 12, the third electrode 13 and the additional electrodes 17 to form at least two dust collecting electric fields.

It can be understood that, within a certain numerical range, the greater the number of the additional electrodes 17, the greater the utilization rate of the charged electric field of the single dust removal unit 10, and the better the dust collection effect; however, if the number of the additional electrodes 17 is too large, the requirement for the charging electric field becomes too high. Optionally, the number of the additional electrodes 17 is greater than or equal to 1 and less than or equal to 8, and more specifically, the number of the additional electrodes 17 may be greater than or equal to 1 and less than or equal to 5, that is, the number of the additional electrodes 17 may be selected to be 1, 2, 3, 4, or 5. The number of the additional electrodes 17 is respectively described as an odd number (taking 1 as an example) and an even number (taking 2 as an example).

Before describing the number of the additional electrodes 17, the polarity and structure of the first electrode 11 and the second electrode 12 will be described below for convenience of describing the formation of the dust collecting electric field.

Typically, the first sub-electrode 111 is grounded, i.e. the first electrode 11 is grounded, and the second electrode 12 is a high voltage electrode, so that the charged electric field can be formed, and the electric property of the charged particle pollutants can be the same as that of the second electrode 12. In a particular embodiment, a positive high voltage may be applied to the second electrode 12, and a negative high voltage may also be applied to the second electrode 12.

In particular, the second electrode 12 may be a wire-like structure, e.g., the second electrode 12 is a corona wire. Alternatively, the first electrode 11 may be a metal wire such as a tungsten wire, a molybdenum wire, or a stainless steel wire. Optionally, the diameter of the first electrode 11 is greater than or equal to 0.01 mm and less than or equal to 1.

Of course, the second electrode 12 may also be configured as a point discharge structure, i.e., the second electrode 12 has a plurality of discharge points, such as needle-shaped discharge points or saw-toothed discharge points. Thus, the discharge of the second electrode 12 can be facilitated.

Specifically, the first electrode 11 is generally configured in a plate shape, that is, the first electrode 11 is an electrode plate; and/or, the third electrode 13 is generally configured in a plate shape, that is, the third electrode 13 is an electrode plate. Therefore, the compactness of the electrostatic dust removal module 100 can be enhanced, the electrode manufacturing difficulty is reduced, and the cost is reduced.

Specifically, the additional electrode 17 is generally provided in a plate shape, that is, the additional electrode 17 is an electrode plate. Therefore, the compactness of the electrostatic dust removal module 100 can be enhanced, the electrode manufacturing difficulty is reduced, and the cost is reduced.

Optionally, the first electrode 11, the third electrode 13 and the additional electrode 17 are arranged parallel to each other.

Further, as shown in fig. 1 to 4, the number of the additional electrodes 17 is 1. Specifically, the additional electrode 17 includes a fourth electrode 171 disposed between the second sub-electrode 112 and the third electrode 13, and the dust collecting electric field includes a first dust collecting electric field formed between the second sub-electrode 112 and the fourth electrode 171 and a second dust collecting electric field formed between the fourth electrode 171 and the third electrode 13.

In this way, by disposing the fourth electrode 171 between the second sub-electrode 112 and the third electrode 13, the first dust collecting electric field and the second dust collecting electric field can be formed between the fourth electrode 171 and the second sub-electrode 112 and the third electrode 13, respectively, i.e. two dust collecting electric fields can be formed, and the structure of the dust removing unit 10 and the electrostatic dust removing module 100 can be simplified.

Specifically, the fourth electrode 171 may be a high voltage electrode, the second sub-electrode 112 is grounded (i.e., the first electrode 11 is grounded), and the third electrode 13 is grounded. Thus, the circuit for forming the dust collecting electric field can be simplified. Of course, when the first sub-electrode 111 and the second sub-electrode 112 are separately disposed at intervals, the fourth electrode 171 may be grounded, the second sub-electrode 112 is a high voltage electrode, and the third electrode 13 is a high voltage electrode, so as to form the first dust collecting electric field and the second dust collecting electric field.

Specifically, the electrical property of the fourth electrode 171 is generally the same as the electrical property of the second electrode 12, that is, the fourth electrode 171 is a repeller, and in this case, the second sub-electrode 112 and the third electrode 13 are collectors.

For example, when a positive high voltage is applied to the second electrode 12, and a positive high voltage is applied to the fourth electrode 171, to repel and collect the charged particle contaminants onto the second sub-electrode 112 and the third electrode 13. As another example, when a negative high voltage is applied to the second electrode 12, and a negative high voltage is applied to the fourth electrode 171, the charged particle contaminants are repelled and collected on the second sub-electrode 112 and the third electrode 13.

Of course, in other embodiments, the electrical property of the fourth electrode 171 may be opposite to the electrical property of the second electrode 12, that is, the fourth electrode 171 is a collector, and in this case, the second sub-electrode 112 and the third electrode 13 are repellers.

In another embodiment of the present invention, as shown in fig. 5 to 8, the additional electrode 17 includes a fifth electrode 172 and a sixth electrode 173 sequentially disposed between the second sub-electrode 112 and the third electrode 13, and the dust collecting electric field includes a third dust collecting electric field formed between the second sub-electrode 112 and the fifth electrode 172, a fourth dust collecting electric field formed between the fifth electrode 172 and the sixth electrode 173, and a fifth dust collecting electric field formed between the sixth electrode 173 and the third electrode 13. Thus, three dust collecting electric fields can be formed.

Specifically, the second sub-electrode 112 is grounded (i.e., the first electrode 11 is grounded), the fifth electrode 172 is a high voltage electrode, the sixth electrode 173 is grounded, and the third electrode 13 is a high voltage electrode, so as to form a third dust collecting electric field, a fourth dust collecting electric field, and a fifth dust collecting electric field.

Specifically, the electrical property of the fifth electrode 172 and the third electrode 13 is generally the same as the electrical property of the second electrode 12, that is, the fifth electrode 172 and the third electrode 13 are repellers, and the second sub-electrode 112 and the sixth electrode 173 are collectors.

For example, when a positive high voltage is applied to the second electrode 12, and a positive high voltage is applied to the third electrode 13 and the fifth electrode 172, the charged particle contaminants are repelled and collected onto the second sub-electrode 112 and the sixth electrode 173. As another example, when a negative high voltage is applied to the second electrode 12, and a negative high voltage is applied to the third electrode 13 and the fifth electrode 172, the charged particle contaminants are repelled and collected onto the second sub-electrode 112 and the sixth electrode 173.

Further, as shown in fig. 9 to 13, the dust removing unit 10 further includes a porous dust collecting member 19, and the porous dust collecting member 19 is provided in the dust collecting electric field.

Specifically, the porous dust collecting member 19 is provided with an air inlet gap 191 (not shown) communicated and distributed along an air inlet direction and a dust collecting flow gap 192 (not shown) communicated and distributed along an electric field direction of a dust collecting electric field, and the air inlet gap 191 is communicated with the dust collecting flow gap 192.

It can be understood that the porous dust collecting member 19 is provided with air inlet gaps 191 which are communicated and distributed along the air inlet direction and through which the flowing air can pass; the porous dust collecting member 19 is provided with dust collecting flow gaps 192 communicated and distributed along the electric field direction of the dust collecting electric field, and the air inlet gaps 191 are communicated with the dust collecting flow gaps 192 to allow the charged particle pollutants in the air to pass through, so that the charged particle pollutants are adsorbed/collected to the collector.

Specifically, the flowing air enters the porous dust collecting member 19 after entering the dust collecting electric field, and continues to move in the air inlet direction along the air inlet gap 191; meanwhile, the charged particle pollutants in the air can move towards the collector through the dust collecting flowing gap 192 under the action of the dust collecting electric field, so that the charged particle pollutants are adsorbed on the collector, and the electrostatic dust collection effect is achieved.

Moreover, through the arrangement of the porous dust collecting member 19, the flowing air can flow in the gap in the porous dust collecting member 19, the flowing area of the flowing air can be increased, and the moving time of the flowing air in the dust collecting electric field can be prolonged, so that more charged particle pollutants can be conveniently adsorbed/collected to the collector, and the electrostatic dust collection effect can be improved. Meanwhile, the porous dust collecting member 19 itself also has a dust collecting effect, which can further improve the dust removing effect to improve the cleanliness of the indoor air.

On the other hand, the arrangement of the porous dust collecting member 19 can enhance the dust collecting effect of the dust collecting electric field, so that the thickness of the dust collecting electric field in the air inlet direction can be reduced on the premise of ensuring the dust collecting effect, thereby facilitating the reduction of the overall thickness of the electrostatic dust collection module 100 and facilitating the realization of the miniaturized design of the electrostatic dust collection module 100.

Further, the porous dust collecting member 19 is generally an insulator, and the provision of the porous dust collecting member 19 also allows the first electrode 11, the third electrode 13, and the additional electrode 17 to be hidden, so that the external insulation of the electrostatic precipitation module 100 can be improved, and the safety of use of the electrostatic precipitation module 100 can be improved.

In addition, by providing the porous dust collecting member 19 in the dust collecting electric field, the restriction among the first electrode 11, the dust collecting electrode, and the third electrode 13 can be increased, thereby contributing to the improvement of the structural strength of the electrostatic precipitator module 100.

The utility model discloses electrostatic precipitator module 100 through set up porous collection dirt piece 19 in the collection dirt electric field, not only can strengthen the dust removal effect, still can improve electrostatic precipitator module 100's safety in utilization.

Further, as shown in fig. 11, the porous dust collecting member 19 is also provided in the charging electric field. Thus, the first electrode 11 and the second electrode 12 can be further hidden, so that the external insulation of the electrostatic dust removal module 100 can be improved, and the use safety of the electrostatic dust removal module 100 can be improved; but also increases the binding force between the porous dust collecting members 19 and the respective electrodes, thereby contributing to further improvement of the structural strength of the electrostatic precipitation module 100.

Specifically, as shown in fig. 11, the porous dust collecting member 19 includes a dust collecting section 196 disposed in a dust collecting electric field and an extension section 197 disposed at one end of the dust collecting section 196, wherein the extension section 197 is disposed in an electric charge electric field.

Optionally, the extension 197 may be filled with a full charge electric field to better hide the second electrode 12; the charging electric field can be partially filled to ensure the charging effect on particle pollutants in the air.

In this embodiment, as shown in fig. 11, the extension 197 is partially filled with a charged electric field. Specifically, the extension section 197 is disposed close to the first sub-electrode 111, and a charging gap is disposed between the extension section 197 and the second electrode 12, and the charging gap is used for allowing air to pass through rapidly, so as to ensure a charging effect and a charging efficiency on particulate pollutants in the air. Thus, the hiding effect of the first electrode 11 and the second electrode 12 can be ensured, and the external insulation of the electrostatic dust removal module 100 can be ensured; but also can ensure the charging effect and charging efficiency of the particle pollutants in the air.

Specifically, as shown in fig. 11, the dust collecting section 196 includes at least two dust collecting portions (not shown), and the at least two dust collecting portions are correspondingly disposed in at least two dust collecting electric fields one by one; the extension 197 is disposed on the dust collecting part disposed near the second sub-electrode 112. In this way, the porous dust collecting member 19 can be better packed in the dust collecting electric field.

Optionally, the dust collecting part is filled with a dust collecting electric field.

Specifically, at least two dust collecting parts are connected into a whole. Thus, not only can the structural strength of the porous dust collecting member 19 and the electrostatic precipitation module 100 be improved; the corresponding assembly steps can also be reduced. Of course, in other embodiments, at least two dust collecting parts can be separated from each other, or some of them can be connected into a whole.

In the embodiment, the form of the porous structure of the porous dust collecting member 19 is various, and the following description is only illustrative, and those skilled in the art can easily conceive more porous structure solutions based on the disclosure of the present application.

In some embodiments of the porous dust collecting member 19, the porous structure of the porous dust collecting member 19 is simple to realize low wind resistance ventilation, as exemplified below:

in a first embodiment of the porous dust collection member 19, as shown in fig. 9-11, said porous dust collection member 19 comprises at least two first vertical grid tabs 193 extending in the direction of the incoming air, said first vertical grid tabs 193 being arranged at an angle to the first side of the first electrode 11. As the name implies, the first side of the first electrode 11 refers to the side of the first electrode 11 which is located at the first side of the first electrode 11.

It will be appreciated that the first vertical grid piece 193 is disposed at an angle to the first side of the first electrode 11, which can also be described in another way: the first vertical grid piece 193 is disposed at an angle to the side of the third electrode 13 facing the first electrode 11.

It will be appreciated that in the first embodiment of the porous dust collection member 19, the air intake gap 191 and the dust collection flow gap 192 are of the same gap structure, i.e., the gap between two adjacent first vertical grid pieces 193. Specifically, the flowing air may flow in the gap between two adjacent first vertical grid plates 193 along the air intake direction, and the charged particle contaminant may also flow in the gap between two adjacent first vertical grid plates 193 along the electric field direction of the dust collecting electric field, so that the charged particle contaminant is adsorbed/collected to the collector.

Thus, by providing at least two first vertical grid pieces 193 to form the air intake gap 191 and the dust collection flow gap 192, not only the structure of the porous dust collection member 19 can be simplified, the production cost can be reduced, but also low windage ventilation can be realized.

In a first embodiment of the porous dust collection piece 19, optionally, as shown in fig. 11, the first vertical grid piece 193 is perpendicular (allowing for assembly errors) to the first side of the first electrode 11. In this manner, the flow of the charged particle contaminants may be facilitated to facilitate the adsorption/collection of the charged particle contaminants to the first electrode 11 or the third electrode 13.

Of course, in a variant of the first embodiment of the porous dust collection member 19, said first vertical grid piece 193 may also be arranged at an acute angle to the first side of the first electrode 11.
