Description

Air Purifier {AIR PURIFIER}

The present invention relates to an air purifier.

In recent years, interest in air pollution has greatly increased both at home and abroad. In particular, air pollution in China is getting worse, and there are many regions in Korea that maintain the worst level due to fine dust and yellow dust from China. Therefore, although the demand for air purifiers is increasing, there are many limited areas to cope with only with filters of air purifiers.

On the other hand, the indoor total heat exchanger can control the temperature and humidity, and there is a fiber filter as a fine dust purification device, but problems are derived due to the limitation of lifespan and low lifespan.

Currently widely used air purifiers are largely classified into two types. One is a method using a filter and the other is a method using a charged dust collection plate.

A method of using a filter separates dust by allowing air to pass through a filter having numerous fine pores and trapping dust in the air through the fine pores of the filter.

However, in the method using a filter, if the hole size of the filter is made very small to increase the efficiency of air purification, pressure loss increases when air is sucked into the air purifier, resulting in increased power consumption and contamination by dust. Since the filter must be frequently washed or replaced, maintenance is cumbersome and uneconomical.

The method of using a charged dust collecting plate is a method of collecting (removing) dust or harmful contaminants in the air in the form of particles by electrifying the dust or harmful pollutants in the charging part (ionizer) and then collecting (removing) the air with the electric suction force of the dust collecting plate (collector) having the opposite polarity.

A conventional electrostatic precipitator includes a charging unit that charges dust by receiving a high voltage and generating a corona discharge, and a dust collection plate that collects the charged dust.

However, since the electric dust collector uses the dust collecting plate disposed in parallel with the direction of air movement, the contact area and contact time between the dust collecting plate and air during air movement is reduced. Accordingly, there is a problem in that the dust contained in the air passes through without sticking to the dust collection plate.

Also, in the conventional electric precipitator, the amount of charge of the ionizer or the length of the precipitator must be increased in order to improve the precipitate collection capability. Here, increasing the length of the dust collector causes a problem in that the size of the entire product also increases.

In addition, when the length of the dust collector is increased, it is necessary to increase the speed of introducing outside air. However, there is a problem in that the dust collection efficiency decreases because the electric suction power is adversely affected when the outdoor air introduction rate increases.

1 is a perspective view of one side of an air purifier according to an embodiment of the present invention, FIG. 2 is a perspective view of the other side of an air purifier according to an embodiment of the present invention, and FIG. This is a front view of an air purifying device according to an exemplary embodiment in a state in which a door is opened.

1 to 3 , the air purifying device 100 according to an embodiment of the present invention may include a main body 110, a charging unit 130, and a dust collecting unit 140.

The air purifier 100 is an electrostatic precipitator type air purifier that can be installed on a ceiling surface of a room, and can improve space efficiency by not occupying an installation space in the room.

Here, an air circulation unit may be installed at the front or rear end of the air purifier 100. The air circulation unit includes a photocatalyst filter, an ultraviolet irradiation unit, and an ozone filter to primarily or secondarily purify external air. In addition, the air circulation unit may further include a blowing unit (not shown) for supplying a constant amount of air so that outside air is introduced into the inlet 110a of the main body 110 and flows toward the outlet 110b in the air purifier 100. there is.

At this time, the air purifier 100 is a horizontal electrostatic precipitator air purifier disposed horizontally on the ceiling. When outside air is introduced and the outside air moves within the air purifier 100, fine dust is removed by gravity from the air purifier ( 100), it is possible to provide an optimal inflow rate so as not to settle to the lower side. This may be supplied from a blower (not shown) installed at the front end.

In this way, the air purifying device 100 can be manufactured as a low-cost, popular type by using a minimal configuration for adsorbing dust contained in external air in an electric precipitator method.

For example, a photocatalyst filter has a photocatalyst coated on its surface to adsorb primary dust when external air passes through. Here, the primary dust may be volatile organic compounds (VOCs) as precursors of ultrafine dust with a size of several microns.

The photocatalyst may be titanium dioxide (TiO2). Titanium dioxide has high photoreactivity, is abundant in resources, is inexpensive, has excellent durability and abrasion resistance as a photocatalyst, is safe in itself, and is non-toxic, so it is environmentally friendly because it does not cause secondary pollution even when discarded.

The ultraviolet irradiator irradiates the photocatalyst filter with ultraviolet rays to remove primary dust adsorbed on the photocatalyst filter. That is, the ultraviolet irradiator directly irradiates ultraviolet rays to the photocatalyst filter to generate a photoreaction to decompose and remove the primary dust adsorbed on the photocatalyst filter with carbon dioxide and water.

As described above, the photocatalytic filter serves to filter primary dust from the outside air, and in the process, the ultraviolet irradiation unit removes the adsorbed primary dust. Accordingly, the photocatalytic filter can be used semi-permanently without replacement.

The photocatalyst filter is disposed at a position corresponding to the ultraviolet irradiation unit in order to effectively remove primary dust adsorbed on the photocatalyst filter.

The ozone filter can remove ozone generated in the process of charging dust in the air purifier 100 from outside air. The ozone filter may be installed at the rear end of the air purifying device 100.

The main body 110 may have a square shape to facilitate installation on the ceiling surface. That is, the main body 110 may have a flat surface installed on the ceiling surface, and a space for accommodating the charging unit 130 and the dust collecting unit 140 may have a rectangular shape.

The main body 110 may be provided with an inlet 110a through which external air flows into one side of the air purifier 100 in the horizontal direction. 1 to 3, the inlet 110a may be provided on the right side of the air purifying device 100.

At this time, the inlet 110a may be provided with an inclined plate 113 so that external air is concentrated on the charging unit 130 . Referring to FIG. 1 , the inclined plate 113 may be provided to extend from the edge of the inlet 110a toward the center of the inlet 110a.

That is, the inclined plate 113 may be provided to extend from the four side edges of the inlet 110a toward the center of the inlet 110a. Here, the inclined plate 113 may be inclined at a predetermined angle.

Accordingly, the air purifying device 100 may induce the inflow of external air and simultaneously improve the inflow speed by concentrating the external air toward the center of the inlet 110a when it is introduced into the inlet 110a.

In addition, the main body 110 may be provided with an outlet 110b through which purified air is discharged on the other side of the air purifier 100 in the horizontal direction. Referring to Figure 2, the outlet (110b) may be provided with a rectangular frame.

The body 110 may include a first door 111 and a second door 112 provided along one side. Here, the main body 110 may have openings having corresponding shapes at positions corresponding to the first door 111 and the second door 112 .

The first door 111 may be provided at a position corresponding to the charging unit 130 on one side of the main body 110 . That is, the first door 111 may be provided on the side of the inlet 110a. 1 to 3, the first door 111 may be provided on the right side of one side (front in the drawings) of the air purifier 100.

At this time, the first door 111 may be provided to open and close. That is, the first door 111 may be opened to expose the charging unit 130 built in the main body 110 to the outside. As a result, the operator can easily access the charging unit 130 .

The second door 112 may be provided at a position corresponding to the dust collecting unit 140 on one side of the main body 110 . That is, the second door 112 may be provided on one side of the first door 111 toward the outlet 110b.

For example, in FIGS. 1 to 3 , the second door 112 may be provided on the left side of one side (front in the drawings) of the air purifier 100 .

At this time, the second door 112 may be provided to open and close. That is, the second door 112 may be opened to expose the dust collecting unit 140 built in the main body 110 to the outside. As a result, the operator can easily access the dust collecting unit 140 .

The charging unit 130 may be provided on the inlet side of the main body 110 . The charging unit 130 may charge dust included in external air introduced through the inlet 110a. Here, the charging unit 130 may be provided with a plurality of electrodes for charging dust.

At this time, a high voltage may be applied to the charging unit 130 under the control of the control unit 170 as will be described later. Accordingly, the charging unit 130 may generate a corona discharge between the internal electrodes by the applied high voltage.

The charging unit 130 may charge the dust included in the external air to become electrically charged through the corona discharge. Here, the charged dust may be fine dust on the order of several tens of micrometers.

The charging unit 130 may be a carbon brush. Accordingly, the charging unit 130 can suppress ozone generated in the process of charging the dust. Accordingly, the air purifying device 100 can prevent air pollution caused by a large amount of AM.

The charging unit 130 may be provided on a portion exposed by the inclined plate 113 of the inlet 110a. That is, the charging unit 130 can be charged while the external air concentrated by the inclined plate 113 toward the center of the inlet 110a is introduced.

The dust collecting unit 140 may be provided at the rear end of the charging unit 130 inside the main body 110 . Here, the dust collecting unit 140 may include a plurality of dust collecting plates 141 arranged in series along the horizontal direction of the main body 110 .

In addition, each of the plurality of dust collecting plates 141 may be formed in a flat rectangular shape. Here, both sides of the plurality of dust collecting plates 141 may be coupled to the support 142 in a sliding manner.

At this time, the dust collecting unit 140 may electrically collect dust charged by the charging unit 130 from the dust collecting plate 141 as the outside air moves. Here, each of the plurality of dust collection plates 141 may be charged with a polarity opposite to that of the charged primary dust.

Specifically, when outside air moves from the charging unit 130 to the dust collecting unit 140, dust charged by the charging unit 130 adheres to the plurality of dust collecting plates 141 by electrical attraction, and thus, outside Dust can be removed from the air.

On the other hand, if the dust collected on the dust collecting plate 141 is saturated, it is difficult to collect dust any more, so the dust collecting plate 141 needs to be washed at regular intervals. At this time, when one dust collecting plate 141 is manufactured and used in a relatively large size, it causes inconvenience during washing, and there is a high possibility that the dust collecting plate 141 is damaged during the washing process.

Since the air purifying device 100 according to an embodiment of the present invention is provided with a plurality of relatively small dust collecting plates 141, it is possible to easily clean the dust collecting plate 141, and during washing, the dust collecting plate 141 damage can be prevented.

Referring to FIG. 3 , the dust collection unit 140 may be configured in multiple stages with respect to the longitudinal direction of the main body 110 and arranged in series from the charging unit 130 side to the outlet 110b side. Here, the dust collecting unit 140 may further include a support 142 supporting the plurality of dust collecting plates 141 .

At this time, the support 142 may be disposed at regular intervals from the charging unit 130 side to the discharge port 110b side. That is, the supports 142 may be arranged at regular intervals to form a space into which the dust collecting plate 141 is inserted.

Here, the dust collection plate 141 may be coupled to the support 142 in a sliding manner. That is, when the dust collecting plate 141 is coupled to the supports 142 provided on both sides, it may be coupled in a sliding manner from the side of the second door 112 toward the inside of the main body 110 .

For example, the support 142 may be provided with a slot at a portion where the dust collecting plate 141 is coupled along the height direction. That is, the dust collection plate 141 may slide along the slot of the support 142 .

In addition, the support 142 may be coupled with a plurality of dust collecting plates 141 such that an angle thereof is adjustable. That is, the plurality of dust collection plates 141 may move in the height direction of the main body 110 along the support 142 . For example, the dust collecting plate 141 may be disposed inclined as one side is fixed and the other side moves in the height direction of the main body 110 .

At this time, the plurality of dust collecting plates 141 may be disposed such that external air moves along the surfaces of the plurality of dust collecting plates 141 . Specifically, the plurality of dust collecting plates 141 may be arranged in multiple stages in the longitudinal direction of the air purifying device 100 . That is, the plurality of dust collecting plates 141 may be arranged in series in the longitudinal direction of the air purifying device 100 .

In addition, the plurality of dust collecting plates 141 may be spaced apart at regular intervals and arranged in parallel between the dust collecting plates 141 adjacent to each other in the height direction of the air purifying device 100 . In this way, the plurality of dust collecting plates 141 may form a movement path of external air therebetween.

On the other hand, when a plurality of dust collecting plates 141 arranged in series are arranged in a straight line along the longitudinal direction of the air purifier 100, the movement direction of the plurality of dust collecting plates 141 and the outside air are parallel, so that the outside air moves. The contact area and contact time between the time dust collecting plate 141 and the outside air are reduced.

Accordingly, the charged dust included in the external air does not stick to the dust collecting plate 141 and the external air can pass through the dust collecting unit 140 as it is. In particular, such a problem is that the faster the moving speed of the outside air is, the more it tends to pass without sticking to the dust collector 140.

To solve this problem, in the air purifying device 100, the plurality of dust collecting plates 141 may be disposed inclined at a predetermined angle with respect to the moving direction of the external air. Here, the inclined angle of the plurality of dust collecting plates 141 may be 10 degrees to 20 degrees, preferably 15 degrees.

Accordingly, the air purifying device 100 according to an embodiment of the present invention can improve the dust collecting efficiency of the dust collecting plate 141 by increasing the contact area and contact time between the dust collecting plate 141 and external air.

For example, the plurality of dust collecting plates 141 arranged in series in the longitudinal direction of the main body 110 may be arranged in an oblique shape in the same direction for each stage. As another example, the plurality of dust collecting plates 141 may be repeatedly arranged in an oblique shape in different directions for each stage. Preferably, as shown in FIG. 3 , the plurality of dust collecting plates 141 may be arranged in a zigzag form for each stage.

4 is a side view of an air purifying device according to an embodiment of the present invention in an open state, and FIG. 5 is an upper perspective view of an air purifying device according to an embodiment of the present invention in an open state.

Referring to FIG. 2 , a first hydraulic slider 111a may be provided on one side of the first door 111 . For example, the first door 111 may be provided with a first hydraulic slider 111a on the side of the second door 112 . At this time, one side of the first hydraulic slider 111a may be coupled to the body 110 and the other side may be coupled to the first door 111 .

Here, the first hydraulic slider 111a can open and close the first door 111 by sliding linearly by hydraulic pressure. That is, the first hydraulic slider 111a linearly slides from the inside to the outside of the main body 110, so that the first door 111 can be opened upward in a state where the opening of the main body 110 is closed.

Referring to FIG. 5 , the first door 111 may be rotatably coupled to the body 110 through the first hinge 114 . Here, the first hinge 114 may be a rotatable coupling member. That is, the first hinge 114 is coupled to a portion where one side of the first door 111 and one side of the main body 110 are coupled and is rotatable with respect to the main body 110 according to the opening and closing of the first door 111. .

In this way, the first door 111 can be opened and closed at one side of the main body 110 by the linear sliding of the first hydraulic slider 111a and the rotation of the first hinge 114 at the same time.

Referring to FIGS. 2 and 4 , the second door 112 may be provided with a pair of second hydraulic sliders 112a and 112b on both sides thereof. For example, the second door 112 may be provided with second hydraulic sliders 112a and 112b on the first door 111 side and the outlet 110b side, respectively. At this time, one side of each of the second hydraulic sliders 112a and 112b may be coupled to the main body 110 and the other side may be coupled to the second door 112 .

Here, the second hydraulic sliders 112a and 112b can open and close the second door 112 by linearly sliding by hydraulic pressure. That is, each of the second hydraulic sliders 112a and 112b linearly slides from the inside to the outside of the main body 110, so that the second door 112 can be opened upward in a state in which the opening of the main body 110 is closed.

Referring to FIG. 5 , the second door 112 may be rotatably coupled to the body 110 through the second hinge 115 . Here, the second hinge 115 may be a rotatable coupling member. That is, the second hinge 115 is coupled to a portion where one side of the second door 112 and one side of the main body 110 are coupled and is rotatable with respect to the main body 110 according to the opening and closing of the second door 112. .

In this way, the second door 112 can be opened and closed at one side of the main body 110 by linear sliding of the second hydraulic sliders 112a and 112b and rotation of the second hinge 115 at the same time.

Accordingly, in the air purifying device 100 according to an embodiment of the present invention, the first door 111 and the second door 112 are easily opened and closed even when installed on the upper part of the ceiling, and the dust collecting plate 141 is removed. Since it is easy to slide and couple to the support 142, overall maintenance of the device can be facilitated.

For example, when the air purifier 100 is installed on the ceiling surface, the operator installs the first hydraulic slider 111a and the second hydraulic slider 112a installed on both sides of the first door 111 and the second door 112, 112b) can easily open the first door 111 and the second door 112.

In addition, since the dust collecting plate 141 is individually manufactured in multiple stages, a worker can easily attach and detach the dust collecting plate 141 from the main body 110 in a sliding manner while the second door 112 is open.

6 is a side view of an air purifying device according to an embodiment of the present invention, and FIG. 7 is a side view of the air purifying device according to an embodiment of the present invention.

Referring to FIG. 6 , the main body 110 may be provided with an inclined plate 113 at the side of the inlet 110a. The inclined plate 113 is provided to extend from the rim of the main body 110 toward the center, thereby inducing the inflow of external air and improving the inflow speed.

Referring to FIG. 7 , the main body 110 may be provided in a square shape on the side of the outlet 110b. Here, the support 142 may be provided on both sides of the outlet 110b. That is, the support 142 may be provided in the width direction of the main body. Here, the width direction means the left-right direction in FIG. 7 .

Accordingly, the dust collection plate 141 may be coupled to the support 142 in a sliding manner in the width direction. That is, the dust collection plates 141 may be coupled in parallel in multiple stages in the height direction on the support 142 .

8 is a block diagram of an air purifying device according to an embodiment of the present invention.

Referring to FIG. 8 , the air purifying device 100 may further include a sensor unit 150, a display unit 160, and a control unit 170.

The sensor unit 150 may be disposed inside the inlet 110a to measure the pollution level of external air. In addition, the sensor unit 150 may be disposed inside the outlet 110b to measure the degree of purification of purified air.

The display unit 160 may be provided on the outside of the main body 110 to display the degree of contamination of external air and the degree of purification of purified air measured by the sensor unit 150 , respectively.

The control unit 170 may control operations of the charging unit 130, the dust collecting unit 140, the sensor unit 150, and the display unit 160. The controller 170 may be a microprocessor built into the air purifier 100.

The control unit 170 may control angles of the plurality of dust collecting plates 141 with respect to the bottom surface of the main body 110 according to the degree of contamination of external air measured by the sensor unit 150 . That is, the controller 170 may control the angle of the dust collecting plate 141 by controlling the sliding of the dust collecting plate 141 along the support 142 .

For example, the control unit 170 may increase the angles of the plurality of dust collecting plates 141 as the degree of contamination of the external air measured by the sensor unit 150 increases. Accordingly, the plurality of dust collecting plates 141 can effectively remove dust from the outside air by increasing the area and time in which external air is in contact with the plurality of dust collecting plates 141 .

Meanwhile, the control unit 170 may control the rotational speed of the blowing unit of the air circulation unit in conjunction with the air circulation unit provided at the front end according to the degree of contamination of the external air measured by the sensor unit 150.

For example, the control unit 170 may control the rotational speed of the blower fan of the air circulation unit installed at the front end to increase as the degree of contamination of the external air measured by the sensor unit 150 increases. Accordingly, the air purifying device 100 can quickly purify the outside air by increasing the speed of the outside air flowing into the main body 110 .

On the other hand, when the angle of the plurality of dust collecting plates 141 is relatively small even though the inflow speed of the outside air is increased, a large amount of outside air can pass through without contacting the plurality of dust collecting plates 141. dust cannot be collected effectively.

Unlike this, despite the increase in the angle of the plurality of dust collecting plates 141, when the inflow speed of external air is relatively slow, the plurality of dust collecting plates 141 act as an obstacle while the external air passes through the dust collecting unit 140, The discharge speed of purified air is slowed down.

Therefore, the control unit 170 appropriately adjusts the rotational speed of the blowing unit of the air circulation unit and the angles of the plurality of dust collecting plates 141 according to the degree of contamination of the external air, thereby responding to the degree of contamination of the external air in real time to purify the external air. , the degree of purification and purification speed of external air can be improved.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented herein, and those skilled in the art who understand the spirit of the present invention may add elements within the scope of the same spirit. However, it will be possible to easily suggest other embodiments by means of changes, deletions, additions, etc., but this will also be said to fall within the scope of the present invention.
