Description

Electrostatic precipitator for compact air cleaners and using the electrostatic precipitator compact air cleaner

technical field

The present invention relates to an electrostatic precipitator for a compact air cleaner and a compact air cleaner using the same, and more particularly, to an electrostatic precipitator capable of having high dust collection efficiency despite being small in size and A stable electrostatic precipitator for compact air cleaners and small air cleaners using this electrostatic precipitator.

Background technique

Currently, widely used air cleaning devices are mainly divided into two categories. One uses filters and the other uses live collector plates.

Air cleaning using a filter separates contaminant particles by forcing the air through a filter with a large number of fine pores so that the contaminant particles in the air are captured by the fine pores of the filter.

However, if the pore size of the filter is made too small in order to improve the air cleaning efficiency, when the air is drawn into the air cleaning device, the pressure loss increases, thereby increasing the power consumption, and the maintenance becomes troublesome due to contamination by pollutant particles The filter needs to be cleaned or replaced from time to time, and eventually, the use of this filter becomes economically unfeasible.

An electrostatic air cleaner that removes contaminant particles by charging particles in the air with ions and passing them between charged collection plates so that contaminant particles with ions attach to the opposite polarity of the charged particles. collection board.

In electrostatic compact air cleaners, the dust collection section consists of alternately arranged collection plates C1 and C2, which are charged to opposite polarities, as shown in Figure 1. However, since the charge is concentrated at the end of the collector plate C1 charged with one polarity that is adjacent to the end of the collector plate C2 charged with the other polarity that is also charged, So the discharge phenomenon is more likely to occur than other parts of the collector plate, sometimes causing sparks.

Conventionally, to prevent sparking, the ends of the collector plates charged with alternating polarity electricity are spaced apart in the longitudinal direction of the collector plates.

However, in the case of such an interval, when arranging the collecting plates, the space efficiency is reduced, thereby reducing the dust collection efficiency because the dust collection area is reduced in the same size space.

In recent years, there has been a growing interest in air cleaners that can be conveniently used at home or in the car, as the room is not easily ventilated frequently due to the large amount of fine dust and yellow dust. Here, the large size of the air cleaner and the troublesome maintenance are factors hindering the use of the air cleaner.

The electrostatic precipitator 1 for a small air cleaner according to the present invention includes a first main electrode plate 10, a plurality of first electrode plates 20, a second main electrode plate 30, a plurality of second electrode plates 40, a plurality of first electrode plates The blocking member 50 and the plurality of second blocking members 60 .

In an exemplary embodiment of the present invention, the first electrode plate 20 , the second electrode plate 40 , the first blocking member 50 and the second blocking member 60 may be provided in plural.

By receiving the high voltage, the first main electrode plate 10 is charged to negative polarity.

The plurality of first electrode plates 20 are respectively arranged at right angles to the first main electrode plates 10 and the plurality of first electrode plates 20 are parallel to each other. One end of each of the first electrode plates 20 is connected to the first main electrode plate 10 , and is charged to a negative polarity similarly to the first main electrode plate 10 .

The second main electrode plate 30 may be disposed opposite to the first main electrode plate 10 with respect to the first electrode plate 20 and may be disposed in parallel with the first main electrode plate 10 . The second main electrode plate 30 is grounded and charged to positive polarity.

That is, by being grounded, the second main electrode plate 30 is regarded as having a positive polarity with respect to the first main electrode plate 10 charged with negative polarity electricity.

Each of the plurality of second electrode plates 40 is charged as a positive electrode by connecting one end thereof to the second main electrode plate 30 in a state where the plurality of second electrode plates 40 are preferably at right angles to the second main electrode plate 30 sex. Each of the second electrode plates 40 may be disposed between the first electrode plates 20 , more precisely, alternately disposed with the first electrode plates 20 , and may be parallel to the first electrode plates 20 .

An electric field is formed between the first electrode plate 20 charged with negative polarity and the second electrode plate 40 charged with positive polarity, and the charged particles passing between the first electrode plate 20 and the second electrode plate 40 can be collected on electrode plates charged with electricity of opposite polarity.

The first and second main electrode plates 10 and 30 and the first and second electrode plates 20 and 40 may be made of a metal material so as to be charged.

Each of the plurality of first blocking members 50 may be disposed at the other end of the first electrode plate 20 to insulate between the other end of the first electrode plate 20 and the second electrode plate 40 . In an exemplary embodiment of the present invention, the first blocking members 50 may be respectively disposed between the other end of each first electrode plate 20 and one end of the second electrode plate 40 adjacent to the first electrode plate 20, And may be arranged to surround the other end of the first electrode plate 20 . The first blocking member 50 is made of insulating material.

Similar to the first blocking member 50, a plurality of second blocking members 60 are made of an insulating material, and are disposed at the other ends of the corresponding second electrode plates 40, so as to be disposed such that the other ends of the second electrode plates 40 and the first An electrode plate 20 is insulated. In an exemplary embodiment of the present invention, the second blocking members 60 may be respectively disposed at one of the other end of each second electrode plate 40 and one end of the first electrode plate 20 adjacent to the second electrode plate 40 . and may be arranged to surround the other end of the second electrode plate 40 .

When ends of electrode plates charged with electricity of different polarities are adjacent to each other, discharge may occur and sparks may be generated, however, since the first blocking member 50 and the second blocking member 60 are made of insulating materials, preventing An electric current occurs between the end of the first blocking member 50 and the end of the second blocking member 60, so the discharge phenomenon does not occur.

As a result, the first electrode plate 20 and the second electrode plate 40 can be arranged more space-efficiently, and the dust collecting area in the same size space can become larger, so that the dust collecting efficiency can be improved. That is, even if the electrostatic air cleaner is made small in size, excellent dust collection efficiency can be exhibited.

When the electrostatic precipitator 1 according to the present invention is installed in a compact air cleaner and used, since the dust collection efficiency may be lowered as the dust is continuously collected in the first electrode plate 20 and the second electrode plate 40, Dust on the first electrode plate 20 and the second electrode plate 40 must be removed periodically.

The electrostatic precipitator 1 according to the present invention is provided with various equipment that is easy to maintain.

The electrostatic precipitator 1 firstly includes a frame 100 as an easy-to-maintain device.

The frame 100 is formed to surround the first and second main electrode plates 10 and 30 , the first and second electrode plates 20 and 40 , and the first and second blocking members 50 and 60 , and is disposed at the first and second portions of the inner space of the frame 100 . The first and second main electrode plates 10 and 30 etc. are directly fixed to the frame 100 .

Therefore, when maintaining the electrostatic precipitator 1 according to the present invention, the components of the electrostatic precipitator 1 provided in the frame 100 can be detached or attached from the compact air cleaner at one time, and the first and second main electrode plates 10 and 30 can be easily arranged in the correct position because the frame 100 can be used as a reference for arranging the first and second main electrode plates 10 and 30 .

Since the charged dust along with the air must flow into the space between the first and second electrode plates 20 and 40, the frame 100 is opened to both sides in the width direction of the first and second electrode plates 20 and 40, and the first and second electrode plates 20 and 40 are opened to both sides. Ends of the first and second main electrode plates 10 and 30 connected to an external power source or the like may be exposed to the outside of the frame 100 .

The frame 100 is made of an insulating material such as plastic so as not to electrically affect the first and second main electrode plates 10 and 30 and the first and second electrode plates 20 and 40 that are charged.

When the electrostatic precipitator 1 according to the present invention further includes the frame 100 , preferably, the first and second electrode plates 20 and 40 and the first and second blocking members 50 and 60 are formed to be detachable from the frame 100 .

Since the first and second electrode plates 20 and 40 in the frame 100 are arranged adjacent to each other with a small interval, it is not easy to remove dust adhering to the first and second electrode plates 20 and 40, however, when the first and second electrode plates 20 and 40 are not easily removed When the two electrode plates 20 and 40 are formed to be detachable from the frame 100, the first and second electrode plates 20 and 40 can be separated from the frame 100 for easy cleaning.

The first and second main electrode plates 10 and 30 each include a main plate p1, a sub plate p2, and a support plate p3, wherein the electrostatic precipitator 1 according to the present invention may further include an auxiliary support b. FIG. 5 shows the first and second main electrode plates 10 and 30 and the auxiliary support bars b.

The main plate p1 is the structure of the first main electrode plate 10 and has a long plate shape. The plurality of sub-boards p2 are disposed to be spaced apart from each other in the longitudinal direction of the main board p1, and extend from the main board p1 in the width direction of the main board p1.

The support plates p3 are formed to be bent from one side of each sub-board p2 so as to protrude to one surface of the sub-boards p2, and the auxiliary supports b are provided to be slightly spaced from the support plates p3 to form between the support plates p3 tiny gaps.

The main board p1, the sub board p2, and the support board p3 may be integrally formed to be all charged, and the auxiliary supporter b may be integrally formed with the frame 100 and not to be charged.

The first electrode plate 20 or the second electrode plate 40 may be detached from the gap between the support plate p3 and the auxiliary support b, and when the first electrode plate 20 is inserted into the gap between the support plate p3 and the auxiliary support b , the first electrode plate 20 is fixed at a predetermined position relative to the first main electrode plate 10, and at the same time one surface of the first electrode plate 20 is in contact with the charged support plate p3, so that the first electrode plate 20 can also have a connection with the first electrode plate 20. The main electrode plate 10 has the same polarity of electricity.

The first main electrode plate 10 for fixing the first electrode plate 20 and charging the first electrode plate 20 may be manufactured using one metal plate. That is, a long plate-shaped metal plate as shown in (a) of FIG. 6 may be cut into the shape shown in (b) of FIG. 6 in which an "L"-shaped member is attached to the widthwise end of the long plate part, and then as shown in Fig. 6(c), the end of the "L"-shaped member may be fabricated by bending upward.

Similar to the connection between the first main electrode plate 10 and the first electrode plate 20, since the auxiliary supporter b is provided at a position slightly spaced from the support plate p3 of the second main electrode plate 30, and the second electrode plate 40 is inserted Between the support plate p3 of the second main electrode plate 30 and the auxiliary supporter b, the second electrode plate 40 is fixed at a predetermined position with respect to the second main electrode plate 30 and is charged by being in contact with the second main electrode plate 30 .

The support plates p3 of the first and second main electrode plates 10 and 30 may be formed to be convexly curved in the direction of the auxiliary support bars b. Preferably, the central area of the support plate p3 may be convexly curved towards the auxiliary support bar b

In this case, the support plate p3 functions as a plate spring to firmly support the first and second electrode plates 20 and 40 by pressing them against the side surfaces of the auxiliary support b 40, and the entrance of the space between the support plate p3 and the auxiliary support bar b is expanded, thereby easily inserting the first and second electrode plates 20 and 40 into the space between the support plate p3 and the auxiliary support bar b.

Fixing grooves g may be formed in the first and second blocking members 50 and 60, respectively.

The other end of the first electrode plate 20 is inserted into the fixing groove g of the first blocking member 50 , and the other end of the second electrode plate 40 is inserted into the fixing groove g of the second blocking member 60 .

In this way, the first and second blocking members 50 and 60 having the fixing groove g surround the other ends of the first and second electrode plates 20 and 40 inserted in the fixing groove g, the other ends of the first and second electrode plates 20 and 40 The other end is insulated from one end of the adjacent first and second electrode plates 20 and 40, and the first and second electrode plates 20 and 40 can be kept in a fixed state, so there is no need to provide separate equipment for fixing the blocking members 50 and 40. 60.

The plurality of first blocking members 50 may be connected to each other by the first connecting bars 70 , and the plurality of second blocking members 60 may be connected by the second connecting bars 80 .

The first connection bars 70 connect the first blocking members 50 respectively formed according to the number of the first electrode plates 20, and the second connection bars 80 connect the second barrier members 60 respectively formed according to the number of the second electrode plates 40, whereby the The first and second blocking members 50 and 60 may be handled as a single body.

Therefore, in order to perform maintenance on the electrostatic precipitator 1, the first and second blocking members 50 and 60 can be easily detached from the first and second electrode plates 20 and 40 at the same time, instead of being removed one by one, and in the first In the case where the first and second blocking members 50 and 60 are arranged in a straight line by the first and second connection bars 70 and 80, respectively, the first and second electrode plates 20 and 40 may be arranged side by side.

The first connection bars 70 may have fixing slits s into which the second electrode plates 40 are inserted, and the second connection bars 80 may have fixing slits s into which the first electrode plates 20 are inserted.

As described above, since the first electrode plates 20 and the second electrode plates 40 are alternately arranged, the second electrode plates 40 pass between the first blocking members 50 and the first electrode plates 20 are between the second blocking members 60 pass through.

The fixing slit s is a hollow space so that the second electrode plate 40 provided between the first blocking members 50 does not interfere with the first connecting bars 70 connecting the first blocking members 50 and is provided on the second blocking member 60 The first electrode plates 20 in between do not interfere with the second connecting bars 80 .

In addition, since the first and second electrode plates 20 and 40 inserted in the fixing slit s are fixed without moving in the thickness direction of the fixing slit s, there is no space between the first and second electrode plates 20 and 40. The gap can be kept constant, which is beneficial to generate an electric field of a predetermined magnitude between the first and second electrode plates 20 and 40 .

Each of the first blocking members 50 and each of the first connection bars 70 may be formed by being separated on both sides in the width direction of the first electrode plate 20 , and each of the second barrier members 60 and each of the second connection bars 80 may be formed by being separated on both sides in the width direction of the second electrode plate 40 .

That is, each of the plurality of first blocking members 50 may be provided as a separator that is divided on both sides in the width direction of the first electrode plate 20 , and the first connection bars 70 may be respectively provided at On both sides in the width direction of the first electrode plate 20, or may be provided in a separator. Each of the first blocking members 50 may have a separator, which may be coupled to each other along the width direction of the first electrode plate 20 .

Similarly, each of the plurality of second blocking members 60 may be provided as a separator that is divided on both sides in the width direction of the second electrode plate 40, and the second connection bars 80 may be respectively provided on the second electrode plate 40. Both sides of the two electrode plates 40, or may be provided in the separator.

In an exemplary embodiment of the present invention, the first and second blocking members 50 and 70 may be provided on both sides in the width direction of the first and second electrode plates 20 and 40 in a bipartite form. For reference, the width directions of the first and second electrode plates 20 and 40 are shown to be parallel to the vertical direction in FIG. 3 .

When the first and second electrode plates 20 and 40 move the first and second blocking members 50 and 60 in the length direction of the first and second electrode plates 20 and 40 or relative to the first and second blocking members 50 and 60 The alignment can be achieved by moving the first and second electrode plates 20 and 40 in the lengthwise direction of the first and second electrode plates 20 and 40 .

However, the first and second barrier members 50 and 60 and the first and second connection bars 70 and 80 connecting the first and second barrier members 50 and 60 are separated at the first and second electrode plates 20 and 40 . In the case of both sides in the width direction, when the first and second electrode plates 20 and 40 and the first and second blocking members 50 and 60 are provided in the frame 100, the first and second electrode plates 20 and 40 Or the first and second blocking members 50 and 60 may be aligned while moving in the width direction and the longitudinal direction of the first and second electrode plates 20 and 40 so that the first and second electrode plates 20 and 40 and the first and second electrode plates 20 and 40 and the first and the second blocking members 50 and 60 can be further easily arranged.

The electrostatic precipitator 1 according to the present invention may further include a gap maintaining member 90 .

The gap maintaining member 90 has a plurality of gap maintaining grooves 91 which are elongated and formed at predetermined intervals in the longitudinal direction, and the first electrode plate 20 and the second electrode plate 40 can be respectively inserted into the gap maintaining grooves 91.

The gap holding member 90 may extend along the arrangement direction of the first electrode plates 20 and the second electrode plates 40 and may be provided at right angles at outer positions in the width direction of the first electrode plates 20 and the second electrode plates 40 so as to pass through the gap The holding grooves 91 , the first electrode plate 20 and the second electrode plate 40 do not move in the longitudinal direction of the gap holding member 90 , thereby constantly maintaining the gap between the first electrode plate 20 and the second electrode plate 40 .

Preferably, the gap maintaining members 90 are provided on both sides in the width direction of the first and second electrode plates 20 and 40, respectively, and at many positions in the longitudinal direction of the first and second electrode plates 20 and 40, such that The first and second electrode plates 20 and 40 may maintain a constant gap in the entire longitudinal direction and the entire width direction. Since the first and second blocking members 50 and 60 are located at both ends of the first and second electrode plates 20 and 40 in the longitudinal direction, the gap maintaining member 90 must be provided between the first and second blocking members 50 and 60 .

In addition, during maintenance of the electrostatic precipitator 1, the gap maintaining member 90 connected to the first connection bar 70 or the second connection bar 80 may be processed together with the first connection bar 70 or the second connection bar 80, so that the electrostatic precipitator 1 Easy to maintain.

Since the first and second electrode plates 20 and 40 of the electrostatic precipitator 1 can be separated from the frame 100, the ease of maintenance work can be further improved.

Preferably, the fan 3 is rotated in order to move the air from the electrostatic precipitator 1 in the direction of the ion generating unit 2 .

The purification of the air by the small air cleaner according to the present invention is performed by sequentially performing the ion generating process of the ion generating unit 2, the process of charging the dust in the air with ions, and the dust collecting process of the electrostatic precipitator 1, and if the ions make the air If the process of charging the dust in the middle does not sufficiently occur, even if the electrostatic precipitator 1 operates, the efficiency of dust collection will become low.

In addition, when the ion generating unit 2 is disposed upstream of the electrostatic precipitator 1 based on the flow of air, the dust in the air should be charged as much as possible by the ions generated by the ion generating unit 2 before the air completely passes through the electrostatic precipitator 1 .

As a result of this, due to the space constraints of the dust to be charged, a higher level of high voltage should be supplied to the ion generating unit 2 to increase the unit volume or energy consumption, thereby overcoming the space constraints.

Therefore, in the exemplary embodiment of the present invention, by flowing the air so as to move in the direction of the ion generating unit 2 in the electrostatic precipitator 1 and then discharging to the outside, the charging process of the dust is allowed to be performed outside the air cleaner, instead of doing it inside an air cleaner.

In other words, the ions generated from the ion generating unit 2 are immediately discharged to the outside of the air cleaner to allow the ions to sufficiently contact dust in the air, and then the wind by the fan 3 flows into the air cleaner and passes through the electrostatic precipitator 1 .

Therefore, the air introduced into the air cleaner first passes through the electrostatic precipitator 1 by the fan 3 , and then passes through the ion generating unit 2 . The position of the fan 3 can be variously determined.

The dust in the air flowing into the air cleaner has been charged by the ions generated in the ion generating unit 2 and removed from the air while passing through the electrostatic precipitator 1 after flowing into the air cleaner, and the purified air moves to the ion generating unit 2 , and flows to the outside again together with the ions generated in the ion generating unit 2 .

As shown in FIG. 7, the ion generating unit 2 may be provided inside the small air cleaner, but in this case, the ions generated by the ion generating unit 2 may adhere to the inner wall of the air cleaner, or the ions may be in the air cleaning It disappears or decreases in number due to various reasons in the process of internal flow.

Therefore, in the exemplary embodiment of the present invention, the discharge electrode, that is, a member that generates ions by a discharge phenomenon, is preferably formed to protrude to the outside of the small air cleaner.

The discharge electrodes may be provided in pairs, and at least a portion of the discharge electrodes may be exposed to the outside of the housing of the air cleaner. Furthermore, in consideration of the airflow of the fan 3, the discharge electrode may be provided near the air outlet of the air cleaner.

In this case, in the compact air cleaner, there is little fear of disappearance of ions generated by the ion generating unit 2, and thus dust particles outside the compact air cleaner can be charged more efficiently. On the other hand, in the exemplary embodiment of the present invention, the length of the discharge electrode protruding outward may be variously determined as required, and is preferably 0 to 10 mm, more preferably 3 mm to 6 mm. In this case, the amount of ions detected outside the air cleaner may appear high.

However, the exemplary embodiments of the present invention are not limited to the above-mentioned range, and may be variously determined according to the structure of the air cleaner, the flow of air, or the operating conditions of the ion generating unit.

In addition to the above configuration, the compact air cleaner according to the present invention may further include a power supply unit (not shown) for supplying power to the ion generating unit 2, the electrostatic precipitator 1 and the fan 3, for controlling the power supply from the power supply A power button (not shown) for the power supply of the unit, a sensor (not shown) for measuring the amount of dust in the air, or a controller (not shown) for adjusting the amount of ion production or dust collection intensity based on the measurement value of the sensor out). While this invention has been described in connection with what is presently considered to be the actual exemplary embodiments, it is to be understood that this invention is not limited to the disclosed embodiments, but on the contrary is intended to cover the spirit and scope of the appended claims. Various modifications and equivalent arrangements within the scope.
