Description

TECHNICAL FIELD [0001] The present invention relates to an electric dust collecting apparatus and a control method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric dust collector and a control method thereof, and more particularly, to an electric dust collector capable of collecting foreign matter such as dust contained in air and a control method thereof.

BACKGROUND ART [0002] Generally, an air conditioner of a vehicle such as an air conditioner or an air purifier has a dust filter that collects and removes foreign matter such as fine dust in the air sucked from the room or outside.

A conventional dust collection filter is a physical collection filter that is provided on a flow path through which air passes and physically filters dust particles larger in size than fine pores of the filter paper to be collected.

Non-woven filters using non-woven fabric filter paper are widely used as the dust collecting filters, and a plurality of filter paper sheets are laminated to increase the collection efficiency.

However, the conventional physical collection filter has a disadvantage in that the dust collection efficiency with respect to fine dust having a small size is not high, and the pressure loss is greatly increased when a plurality of filter sheets are used.

Accordingly, there is an increasing interest in electrostatic dust collecting filters for collecting foreign matters such as fine dust by using electrical attraction.

In the case of the electrostatic dust collecting filter, a dust collecting unit for collecting foreign substances in the air by using electrical attraction is provided. Such a dust collecting unit is more effective for removing small particles than a physical dust collecting filter because it collects foreign substances by electrostatic force.

However, the conventional physical dust collecting filter and electrostatic dust collecting filter have such a configuration that it is impossible to variably control the dust removing performance by varying the dust removing level according to the pollution degree of the air introduced from outside or the degree of driver's demand.

For example, in the case of a physical dust filter, the dust is removed only in accordance with the predetermined performance of the single filter.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electric dust collector and control method thereof that are capable of varying fine dust removing performance according to the air condition or the driver's intention (control level) .

According to an aspect of the present invention, there is provided an image forming apparatus including: a charging unit for discharging electrons through a discharge pin applied with a voltage to charge foreign particles in the introduced air; When a voltage is applied between the first dust collecting electrode and the second dust collecting electrode on both sides of the dielectric dust collecting body, an electric field is formed in the air flow path formed in the dust collecting body and the foreign matter charged by the charging unit, A dust collecting part for collecting the particles; A power supply unit for applying a voltage to the charging unit and the dust collecting unit; And a controller for individually controlling a voltage applied to the charging unit and the dust collecting unit from the power supply unit in accordance with the contamination degree information of the inflowing air or driver request information.

According to another aspect of the present invention, there is provided an image forming apparatus comprising: a charging unit for discharging electrons through a discharge pin applied with a voltage to charge foreign particles in the introduced air; When a voltage is applied between the first dust collecting electrode and the second dust collecting electrode on both sides of the dielectric dust collecting body, an electric field is formed in the air flow path formed in the dust collecting body and the foreign matter charged by the charging unit, A dust collecting part for collecting the particles; A power supply unit for applying a voltage to the charging unit and the dust collecting unit; And a controller for controlling voltages applied to the charging unit and the dust collecting unit from the power supply unit, wherein the controller acquires air pollution degree information or driver request information from a contamination detection sensor or a driver's operating device of the vehicle ; And controlling the voltage applied to the charging unit and the dust collecting unit from the power supply unit, respectively, in accordance with the air pollution degree information or the driver request information.

Thus, according to the electric dust collector according to the present invention and the control method thereof, the dust removing performance can be variably controlled as needed by adjusting the high voltage applied to the charging part and the dust collecting part.

Particularly, when the pollution level of the atmosphere is high and the amount of foreign matter such as dust entering the vehicle interior is high or the driver desires to increase the efficiency and performance of removing foreign matter, dust removal performance of the electric dust collector can be enhanced.

In addition, when the level of pollution in the atmosphere is low or the driver desires to lower the efficiency and performance of removing foreign matter, the dust removing performance of the electric dust collector can be lowered.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains.

FIG. 1 shows a dust collecting mechanism of an electrostatic precipitator to which the present invention can be applied. When air including foreign matter such as dust is introduced, foreign particles charged with negative ions in the charging section 10 are collected in the dust collecting section 20, The dust collecting electrode 22 is moved toward the second dust collecting electrode 22 by an electric field formed between the first dust collecting electrode 21 and the second dust collecting electrode 22 and is collected in a dielectric plate (not shown).

3 is a view showing a configuration of a dust collecting unit in an example of an electric dust collecting apparatus to which the present invention is applied. FIG. 4 is a sectional view showing a structure of a dust collecting unit in an example of an electric dust collecting apparatus to which the present invention is applied. Fig. 5 is a view seen from AA and BB in Fig. 4; Fig.

3 and 4, the dust collecting unit 20 includes a plurality of dust collecting bodies 23 to be stacked, and a first dust collecting electrode 21 and a second dust collecting electrode 22 stacked and disposed therebetween .

Each of the dust collectors 23 has an air passage 25 for guiding an air flow while passing air therein. The dielectric plate 24 made of a material having a dielectric property (for example, plastic) And partition walls 26 of the same material are integrally formed at predetermined intervals therebetween so that a space between the dielectric plate and the partition walls 26 serves as an air flow passage 25 for air flow have.

At this time, the respective air passage flow paths 25 are formed so as to have a closed end surface structure surrounded by a dielectric (plastic) material except for the outlets and the openings at both ends for air inflow and outflow.

The air passage 25 of the dust collecting body 23 is divided into a plurality of air passages 25 by internal partition walls 26 and concretely a plurality of air passageways 25 partitioned by a plurality of partition walls 26 Air flow passages 25 are formed.

As a result, the dust collecting body 23 has a mesh structure in which the dielectric plates 24 and the partition walls 26 are crossed with each other so that air can pass through the air passage 25, which is a space therebetween.

In the above-described structure, each of the air passage flow paths 25 defined by the partition walls 26 forms a passage having a predetermined length in the air flow direction. As compared with the conventional nonwoven filter, It is possible to increase the collection efficiency of the foreign matter through the air flow passage having a certain passage length as well as the passage velocity.

3 to 5, the first dust collecting electrode 21 and the second dust collecting electrode 22, which have different polarities, are electrically separated on a surface of the dust collector 23 at a predetermined interval Respectively.

Another dust collecting body 23 is stacked thereon and a first dust collecting electrode 21 and a second dust collecting electrode 22 which are electrically separated from each other are interposed between the two dust collecting bodies 23 stacked thereon.

In this manner, the dust collecting body 23, the first dust collecting electrode 21 and the second dust collecting electrode 22 are repeatedly stacked repeatedly to constitute the dust collecting unit 20. In the stacked collecting body 23, The first dust collecting electrode 21 and the second dust collecting electrode 22 having different polarities are attached to the outer surfaces of the dust collecting bodies respectively arranged in the same manner.

The first dust collecting electrode 21 and the second dust collecting electrode 22 may be formed by printing a conductive material on one surface of the dust collecting body 23 and may be formed at a predetermined distance from the rim of the dust collecting body 23 And can be formed in the inner region thereof.

The first dust collecting electrode 21 and the second dust collecting electrode 21 are alternately stacked alternately along the stacking direction of the dust collecting body 23.

Therefore, the first dust collecting electrode 21 and the second dust collecting electrode 22 are alternately stacked (sandwiched) between the dust collecting bodies 23 in the direction perpendicular to the air flow direction, .

At this time, as described above, the first dust collecting electrode 21 and the second dust collecting electrode 22 are electrically separated and provided together at a predetermined interval on one surface of each dust collecting body 23.

That is, a first dust collecting electrode 21 and a second dust collecting electrode 22 are provided on one surface of each dust collecting body 23 with a space therebetween, and a first dust collecting electrode 21 And the second dust collecting electrode 22 are disposed.

The first dust collecting electrode 21 and the second dust collecting electrode 22 may not be provided together on one surface of each dust collecting body 23 and only one electrode may be disposed. The dust collecting body 23, The dust collecting body 23, and the second dust collecting electrode 22, as shown in Fig.

In this case, one electrode, that is, the first dust collecting electrode 21 or the second dust collecting electrode 22 is disposed between the stacked dust collectors 23, and between each of the stacked dust collectors 23, The first dust collecting electrode 21 and the second dust collecting electrode 22 are alternately arranged one by one. The first dust collecting electrode and the second dust collecting electrode are disposed on both sides of the respective dust collecting bodies.

In the dust collecting unit 20, the first dust collecting electrodes 21 are electrically connected in parallel and the second dust collecting electrodes 22 are electrically connected in parallel.

Each of the dust collecting electrodes 21 and 22 is connected to the power supply unit 30 so as to receive a voltage through the electrode tabs 21a and 22a extended to protrude outwardly of the dust collecting body 23. The first dust collecting electrode 21 (+) Pole of a power supply unit 30 for applying a high voltage is connected to the second collector electrode 22 and a (-) pole of the power supply unit 30 is connected to the ground.

When a high voltage is applied to the first dust collecting electrode 21 and the second dust collecting electrode 22 from the power supply unit 30, the first dust collecting electrode 21 on both sides of the dust collecting body 23 on which the air passing path 25 is formed, A potential difference is generated between the first dust collecting electrode 21 and the second dust collecting electrode 22, and an electric field is generated between the first dust collecting electrode 21 and the second dust collecting electrode 22 by this potential difference.

That is, as a high voltage is applied between the first dust collecting electrode 21 and the second dust collecting electrode 22, an electric field is formed between the two dust collecting electrodes 21 and 22 and the air passing path 25 of the dust collecting body 23 At this time, the electric field direction is the direction from the first dust collecting electrode 21 at the high potential to the second dust collecting electrode 22 at the low potential.

As the electric field is formed in the air passage 25, ionized foreign matter in the air passing through the air passage 25 is precipitated along the electric field direction, (That is, the dielectric plate) side of the dust collecting body 23.

When the first dust collecting electrode 21 and the second dust collecting electrode 22 are simultaneously formed on one surface of the dust collecting body 23 as described above, the first dust collecting electrode 21 is formed on one surface of the dust collecting body 23, The electrical stability of the dust collecting unit 20 is increased and the amount of generated ozone can be reduced compared with the case where only one of the first and second dust collecting electrodes 22 is formed.

The first dust collecting electrode 21 and the second dust collecting electrode 22 increase the electric dust collecting efficiency while increasing the amount of ozone generated. The first dust collecting electrode 21 and the second dust collecting electrode 22 are arranged together to increase the voltage difference between the first dust collecting electrode and the second dust collecting electrode disposed with the dust collecting body 23 interposed therebetween, The increase in the amount of ozone generated can be suppressed.

FIG. 6 is an exploded perspective view illustrating an electric dust collecting apparatus to which the present invention is applied, including a power supply unit and a controller, and FIG. 7 is a block diagram showing a main configuration of an electric dust collecting apparatus to which the present invention is applied.

As shown in the figure, the electrostatic precipitator includes a charging unit 10 for charging a foreign substance such as dust contained in the air to be charged, a dust collecting unit 20 for collecting dust electrically, a charging unit 10 And a controller 40 for controlling the supply of high voltage to the charging unit 10 and the power supply unit 30 to the dust collecting unit 20. The power supply unit 30 applies a high voltage to the dust collecting unit 20,

The charging unit 10 may include a discharging plate 11 and an inlet 11a, a discharging pin 12 and a conductive mounting unit 13. The dust collecting unit 20 may include a first dust collecting electrode 21 And a dust collecting body 23 including the electrode tab 21a, the second dust collecting electrode 22 and the electrode tab 22a thereof, and the dielectric plate 24 and the partition wall 26 and the air passage 25, As shown in FIG.

Of these, the configurations of the charging section 10 and the dust collecting section 20 have been described in detail with respect to the configuration of the electrostatic precipitator in the foregoing, and thus the description thereof will be omitted.

The controller 40 controls the operation of the power source unit 30 and controls the operation of the charging unit 10 in the power source unit 30. The power source unit 30 is a component that supplies a high voltage to the charging unit 10 and the dust collecting unit 20. [ And the voltage to be applied to the dust collecting unit 20 is controlled.

The power supply unit 30 applies a high voltage to the charging unit 10 and the dust collecting unit 20 separately.

A circuit for controlling the voltages applied to the charging section 10 and the dust collecting section 20 from the power supply section 30 is configured in accordance with the control signal of the controller 40. [

The controller 40 controls the voltage output of the power supply unit 30 or controls the charging unit 10 and the dust collecting unit 20 in the power supply unit 30 in addition to the control signal for controlling the on / off operation of the power supply unit 30. [ And a control signal for individually controlling the voltages applied to the respective electrodes.

The on / off operation of the power supply section 30 can be controlled in accordance with the control signal output from the controller 40 and the voltage output from the power supply section 30 is controlled in accordance with the control signal output from the controller 40 The voltage applied to the charging section 10 and the dust collecting section 20 can be controlled.

In the embodiment of the present invention, the controller 40 is configured to receive signals from the contamination detecting sensor 51 or the operating device 52, and the controller 40 controls the signal or operation of the contamination detecting sensor 51 Off operation of the power supply unit 30 and controls each voltage applied to the charging unit 10 and the dust collecting unit 20 from the power supply unit 30. [

FIG. 8 is a flowchart showing a control method of an electric dust collector according to an embodiment of the present invention. Referring to FIG. 8, the control process will be described below.

When it is required to raise the dust collecting efficiency and performance of the electric dust collector, that is, when it is necessary to increase the dust collecting efficiency and performance according to the air pollution degree information and the driver's request information detected through the pollution detecting sensor 51, The voltage is raised first and the voltage applied to the charging section 10 is increased when an additional rise is required.

This is because the charging unit 10 is a major source of ozone and electromagnetic waves, and the voltage to be applied to the charging unit 10 is raised in priority order, and when a further increase in efficiency and performance is required, Thereby raising the voltage to the next rank.

On the other hand, when it is required to lower the dust collection efficiency and performance of the electric dust collector, that is, to lower the dust collecting efficiency and performance according to the air pollution degree information and driver's demand information, the voltage applied to the charging portion 10 is firstly lowered first, The voltage applied to the dust collecting unit 20 is lowered when additional efficiency and performance lowering are required.

This is also intended to preferentially lower the supply voltage to the charging section 10, which is the main source of ozone or electromagnetic waves.

The pollution detection sensor 51 detects the air pollution degree and inputs the detected air pollution degree to the controller 40. The control unit compares the pollution degree measurement value detected by the pollution detection sensor 51 with predetermined reference values, Decide whether to keep, raise, or lower.

The pollution detection sensor 51 may be installed at a vehicle interior position capable of detecting the pollution degree of the indoor air of the vehicle or may be installed at a predetermined position in the vehicle capable of detecting pollution degree of indoor air or outdoor air flowing into the electric dust collector And can be a sensor for detecting foreign matter concentration such as dust mixed in the air.

8, when the electric dust collector is turned on (S11), the controller 40 applies a predetermined high voltage to the charging unit 10 and the dust collecting unit 20 through the power supply unit 30 (S12).

The controller 40 then acquires the air pollution degree information detected by the contamination detection sensor 51 and the driver request information set by the driver using the in-vehicle control device 52 such as a switch (S13).

Next, the controller 40 determines whether to increase or decrease the dust removing performance from the current performance based on the air pollution degree information and the driver request information (S14, S15).

Here, the current performance may be an initial default value applied when the electric dust collector which has been turned off is ON, or may be a performance that has been changed in the ON state continuously.

If the current concentration of foreign matter in the air detected by the contamination detection sensor 51 is higher than the set value of the current performance and is higher than the set value of the higher performance level, .

On the contrary, when the current concentration of foreign matter in the air detected by the contamination detection sensor 51 is lower than the set value of the current performance and is lower than the set value of the lower performance stage, the controller 40 Can be set.

In addition, if the driver operates the operation device 52 to select a higher performance level compared to the current performance level, it is determined that a performance improvement is necessary. If the lower performance level is selected in comparison with the current performance level, .

The controller 40 outputs a control signal for raising the voltage applied to the dust collection unit 20 from the power supply unit 30 and supplies the control signal to the dust collection unit 20 through the power supply unit 30. [ (S16).

If it is determined in step S18 that further increase of the dust removal performance is required based on the air pollution degree information and driver request information, the controller 40 determines whether the dust removal performance is required to be further increased from the power supply section 30 to the charging section 10 And the voltage applied to the charging unit 10 is raised from the power supply unit 30 through the control signal (S20).

On the other hand, if it is determined that the performance descending is required after step S13, the controller 40 outputs a control signal for lowering the voltage applied to the charging unit 10 from the power source unit 30, The voltage applied to the power supply 10 is first lowered (S17)

If it is determined that further descent of the dust removing performance is required based on the air pollution degree information and the driver request information in step S19 and the controller 40 determines that further descent is required, And outputs a control signal for lowering the voltage, thereby lowering the voltage applied to the dust collecting unit 20 from the power supply unit 30 (S21)

When the dust removing performance is to be increased as described above, the voltage applied to the dust collecting unit 20 is increased in the order of priority, and the voltage applied to the charging unit 10 is increased to a lower level when further performance improvement is required.

On the other hand, when the dust removing performance is to be lowered, the voltage applied to the charging unit 10 is lowered to a lower level, and when the performance is further lowered, the voltage applied to the dust collecting unit 20 is lowered.

In this manner, according to the control method of the electric dust collector according to the present invention, the dust removing performance can be variably controlled as needed by adjusting the high voltage applied to the charging section and the dust collecting section.

Particularly, when the pollution level of the atmosphere is high and the amount of foreign matter such as dust entering the vehicle interior is high or the driver desires to increase the efficiency and performance of removing foreign matter, dust removal performance of the electric dust collector can be enhanced.

In addition, when the level of pollution in the atmosphere is low or the driver desires to lower the efficiency and performance of removing foreign matter, the dust removing performance of the electric dust collector can be lowered.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Forms are also included within the scope of the present invention.
