The present invention relates to a filter device and a cleaner including the same.

In general, a vacuum cleaner uses a vacuum pressure generated by the operation of a motor to suck pollutants, such as hair and dust, together with air, collect the pollutants in a dust collector, and discharge the air to the outside.

Recently, the harmfulness caused by contaminants of relatively small particles such as fine dust has been increasing. Accordingly, high-performance and expensive filtering means are installed in the vacuum cleaner to filter contaminants of small particles by being manufactured in a compact structure like a HEPA filter.

However, when the above-described high-performance filtering means is used for a predetermined period of time, pollutants are adsorbed and filtering performance is deteriorated. Accordingly, the suction power of the vacuum cleaner is reduced, making it difficult to effectively perform the cleaning function. Further, since the cleaner needs to periodically replace the filtering means, there is a problem in that it is inconvenient to use and the maintenance cost is increased.

In addition, when contaminants are adsorbed to the filtering means, the motor may be overheated due to an increase in load acting on the motor, resulting in malfunction or damage.

In addition, very small contaminants such as ultrafine dust are difficult to filter by conventional filtering means, and are discharged to the outside along with air through the filtering means, and may harm human health such as users.

Accordingly, there is a need to develop a filter device that has low maintenance cost and can effectively filter even small particles of contaminants, and a cleaner including the filter device.

In this case, contaminants outside the housing 10 may be introduced into the suction pipe 30 through the suction body 35 together with air and may move toward the suction port.

An outlet (not shown) through which air is discharged to the outside of the housing 10 is formed in the housing 10. In this case, the discharge port discharges air sucked through the suction port, and in this process, some contaminants such as fine dust may be discharged together with the air.

The motor unit 50 is disposed in the housing 10. In this case, the motor unit 50 may be disposed between the inlet and the outlet in the housing 10 as shown in FIG. 1, but is not limited thereto.

For example, the motor unit 50 may include a motor (not shown) and an impeller (not shown).

The motor generates rotational driving force. Such a motor may include various known motors such as a BLDC motor (Brushless Direct Current Motor) or a motor including a carbon brush. Detailed description of this will be omitted.

The impeller is coupled to the motor. When the motor operates, the impeller rotates by the rotational driving force of the motor, and may generate a flow of air from the inlet to the outlet.

The motor unit 50 generates a suction force so that pollutants are sucked together with air. In other words, the motor unit 50 may generate a vacuum pressure inside the housing 10 so that contaminants are sucked together with air.

In more detail, air inside the housing 10 may be discharged to the outside of the housing 10 by rotation of the impeller. At this time, a pressure difference, that is, vacuum pressure, is generated inside the housing 10 with respect to the outside of the housing 10, and air and pollutants outside the housing 10 can be sucked into the housing 10 by the pressure difference. have.

The dust collecting part 70 is formed on the upstream side of the motor part 50 of the housing 10. In this case, the dust collecting unit 70 may be formed inside the housing 10 as shown in FIG. 1.

One side of the dust collecting unit 70 is connected to the suction port. At this time, the dust collecting unit 70 collects some of the pollutants sucked together with the air through the inlet.

In more detail, the dust collecting unit 70 may collect pollutants of relatively large particles among pollutants sucked together with air. At this time, the contaminants of relatively small particles that are not collected by the dust collecting unit 70 may pass through the dust collecting unit 70 and move to the outlet together with air.

A filter member 75 may be disposed inside the dust collecting unit 70. In this case, the filter member 75 includes a known filtering means capable of filtering out inexpensive and large particles such as sponge or nonwoven fabric or cloth, and detailed description thereof will be omitted.

Air and small particles of contaminants discharged from the outlet may be introduced into the filter device 1000. At this time, the filter device 1000 may collect small particles of contaminants and discharge air to the outside.

The filter device 1000 may collect contaminants using water. The specific structure of the filter device 1000 will be described later.

Accordingly, the cleaner 1 according to the present embodiment filters contaminants of large particles in the dust collecting unit 70 on the upstream side of the motor unit 50, and filters small particles in the filter device 1000 on the downstream side of the motor unit 50. By filtering contaminants of various sizes, it is possible to effectively collect and filter contaminants of various sizes, and there is no need to use expensive filtering means such as HEPA filter to filter contaminants of small particles, thus reducing maintenance costs. , It is possible to effectively maintain the cleaning function as it can prevent the reduction of suction power due to contamination of the filter device.

Furthermore, by providing a structure in which small particles of contaminants are collected from the downstream side of the motor unit 50, small particles of contaminants are prevented from being adsorbed to the dust collecting unit 70, thereby acting on the motor unit 50. As the load is reduced, malfunction and damage of the motor unit 50 can be prevented, and suction power of the cleaner can be effectively maintained.

In addition, since the filter device 1000 for collecting small particles of contaminants is disposed on the downstream side of the motor unit 50, the amount of water used for collecting the contaminants can be reduced, and the size of the filter device 1000 It can be downsized.

On the other hand, when the motor unit 50 includes a motor including a carbon brush, small particles of contaminants generated by abrasion of the carbon brush are also air in the filter device 1000 located on the downstream side of the motor unit 50. It can be introduced with and collected.

In this case, the cleaner 1 according to the present embodiment does not need to use a separate filtering means to filter contaminants generated by abrasion of the carbon brush, thereby reducing manufacturing cost and the like.

A filtering area 1150a and an air collection area 1150b are formed in the inner space 1150 of the main body 1100.

Water is accommodated in the filtering region 1150a. In this case, the filtering region 1150a may be formed in a lower region of the inner space 1150 as shown in FIG. 2. In other words, the filtering area 1150a may be a partial area of the inner space 1150 filled with water.

The filtering area 1150a collects pollutants. In this case, the filtering region 1150a may filter air containing pollutants introduced through the inlet line 1200 to be described later.

In more detail, pollutants are introduced into the filtering area 1150a together with air. Contaminants introduced into the filtering area 1150a are filtered by contacting water in the filtering area 1150a, and may remain in the filtering area 1150a. In addition, air may pass through the filtering area 1150a and move outside the filtering area 1150a.

In this case, the filter device 1000 according to the present exemplary embodiment collects pollutants using water in the filtering area 1150a, thereby effectively filtering various pollutants such as particles having a relatively small size.

The air collection region 1150b is formed above the filtering region 1150a as shown in FIG. 2. In other words, the air collection area 1150b may be the remaining area of the inner space 1150 that is not filled with water.

Air that has passed through the filtering area 1150a is collected in the air collection area 1150b. In other words, air from which contaminants have been filtered in the filtering area 1150a may move to the air collection area 1150b.

In this embodiment, the body 1100 may include a container portion 1110 and a lid portion 1120.

The container part 1110 may extend in the vertical direction as shown in FIG. 2.

For example, the container portion 1110 may be provided in a cylindrical shape with an open top. In addition, the container portion is not shown, but may be provided in various forms such as a hexahedral shape.

The lid portion 1120 may extend in the vertical direction as shown in FIG. 2. In this case, the lid part 1120 may be provided in a shape corresponding to the container part 1110 and be coupled to the container part 1110.

For example, the container part 1110 may be provided in a cylindrical shape with an open lower part.

The combination of the container part 1110 and the lid part 1120 may form an inner space 1150 as shown in FIG. 2. At this time, water may be accommodated in at least a part of the container part 1110, that is, a lower region.

The lower area of the container part 1110 containing water forms a filtering area 1150a, and the upper area of the filtering area 1150a, that is, the area surrounded by the upper area of the container part 1110 and the lid part 1120, is air. A collection area 1150b may be formed.

The container part 1110 accommodating water may be made of a light-transmitting material. In this case, the user can easily and effectively check the degree of contamination by the collected pollutants of the water contained in the container unit 1110.

A scale part (not shown) may be formed on a side wall of the container part 1110 made of a light-transmitting material to check the amount of water accommodated in the container part 1110.

In this case, the scale portion is the minimum scale (not shown) corresponding to the minimum capacity of water capable of collecting pollutants, and the maximum amount of water that can be prevented from flowing out of the container unit 1110 during the process of collecting pollutants. It may include a maximum scale (not shown) corresponding to the capacity.

The lid part 1120 may be detachably coupled to the container part 1110 from the upper side of the container part 1110.

In this case, the lid portion 1120 may be coupled to the container portion 1110 containing water before collecting contaminants. Alternatively, the lid part 1120 may be separated from the container part 1110 when it is necessary to inject water into the container part 1110 or when disposing of water in the container part 1110 contaminated by contaminants.

For example, the container portion 1110 and the lid portion 1120 may be screwed. At this time, a male screw part (not shown) is formed on the outer wall of the upper end of the container part 1110, and a female screw part (not shown) is formed on the inner wall of the lid part 1120 to screw with the male screw part of the container part 1110 Can be.

In this case, the lid part 1120 is disposed on the upper side of the container part 1110 and is screwed when rotating in one direction to be coupled to the container part 1110, and when rotating in the other direction, the screw connection is released and the container part ( 1110).

In addition, the container portion and the lid portion are not shown, but may be combined in various separable structures.

Meanwhile, although the main body is not shown, it may be provided in various structures capable of accommodating water in at least a part of the internal space.

In this embodiment, the body 1100 may be detachably coupled to the housing 10.

In this case, the main body 1100 may be coupled to the housing 10 when the cleaner 1 operates to suck the pollutants. Alternatively, the main body 1100 may be separated from the housing 10 when the cleaner 1 ends its operation.

For example, a first locking projection (not shown) may be formed in the housing 10. In addition, a second locking projection (not shown) and a second locking projection (not shown) and a second locking projection (not shown) that engages in the first locking projection to be caught on the first locking projection or the second locking projection is operated to release the locking operation. A button (not shown) may be formed.

When the main body 1100 is coupled to the housing 10, the user may press the operation button so that the second locking projection is engaged. Alternatively, when the main body 1100 is separated from the housing 10, the user may press the operation button so that the second locking protrusion is disengaged.

In addition, although the main body is not shown, it may be detachably coupled to the housing in various ways, such as sliding with respect to the housing.

The inlet line 1200 extends to connect the outside of the main body 1100 and the filtering region 1150a as shown in FIG. 2. In this case, the inlet line 1200 provides a path through which contaminants along with air flow into the filtering region 1150a from the outside of the main body 1100.

In this case, air and small particles of contaminants discharged from the outlet of the housing 10 may flow into the inlet line 1200 and move into the filtering region 1150a, that is, water.

One end of the inflow line 1200 is located in the filtering area 1150a. In other words, one end of the inlet line 1200 may be located in an area in which water is received in the inner space 1150 of the main body 1100.

The other end of the inlet line 1200 may face the outside of the main body 1100, that is, toward the outlet of the housing 10.

In this embodiment, a disturbing part 1400 may be formed at one end of the inflow line 1200 as shown in FIGS. 2, 3 and 4.

The disturbing part 1400 disturbs the water contained in the main body 1100 while the air introduced into the inflow line 1200 moves to the filtering area 1150a. In this case, the disturbed water is more likely to contact pollutants than the water in a stationary state, and pollutants flowing into the filtering area 1150a can be more effectively collected by the disturbed water.

The disturbing part 1400 may extend in the extending direction of the inflow line 1200. One end of the disturbance part 1400 may be connected to one end of the inflow line 1200, and the other end of the disturbance part 1400 may be formed to open toward the filtering region 1150a. In this case, air and pollutants introduced into the inlet line 1200 may move to the filtering region 1150a through the disturbing part 1400.

For example, the disturbance part 1400 may be provided in a form in which the area of the disturbance part 1400 decreases as the other end moves away from one end of the inflow line 1200 as shown in FIG. In this case, the air moving from the disturbance unit 1400 to the filtering region 1150a increases in speed, thereby effectively disturbing water.

In this case, a part of the sidewall of the other end of the disturbance part 1400 may be cut in the extending direction of the disturbance part 1400 as shown in FIG. 4. In this case, the other end of the disturbing unit 1400 is shaken by the air moving from the disturbing unit 1400 to the filtering region 1150a, thereby more effectively disturbing the water.

The disturbing part 1400 may be formed of a material such as rubber, but is not limited thereto.

The discharge line 1300 extends to connect the outside of the main body 1100 and the air collection area 1150b as shown in FIG. 2. At this time, the discharge line 1300 provides a path through which the air collected in the air collection region 1150b is discharged from the air collection region 1150b to the outside of the main body 1100.

In this case, the air that has passed through the filtering region 1150a, that is, air filtered with pollutants, may move to the air collection region 1150b and be discharged to the outside of the main body 1100 through the discharge line 1300.

One end of the discharge line 1300 is located in the air collection area 1150b.

The other end of the discharge line 1300 may face the outside of the main body 1100. In this case, the other end of the discharge line 1300 may face the outside of the main body 1100 rather than the discharge port of the housing 10.

In this embodiment, the inlet line 1200 and the outlet line 1300 may be supported by the lid portion 1120 as shown in FIGS. 2 and 3. In this case, the inlet line 1200 and the discharge line 1300 can be moved inside or outside the container portion 1110 together with the lid portion 1120, so that management is easy and loss can be prevented.

One end of the inlet line 1200 extends vertically from the inside of the container 1110 as shown in FIG. 2 and is located in the filtering region 1150a, and the other end of the inlet line 1200 penetrates the inside of the lid 1120. It extends toward the outlet of the housing 10 and may be supported by the lid portion 1120.

In addition, one end of the discharge line 1300 extends in the vertical direction as shown in FIG. 2 and is located in the air collection area 1150b, and the other end of the discharge line 1300 penetrates the inside of the lid part 1120 and the lid part 1120 It extends toward the outside, that is, to the outside of the main body 1100 and may be supported by the lid portion 1120.

On the other hand, although not shown in other embodiments, the inlet line and the discharge line may be supported by the container.

In this case, one end of the inlet line extends vertically from the inside of the container and is located in the filtering area, and the other end of the inlet line penetrates through the sidewall of the upper end of the container, that is, the sidewall that forms the air collection area, and extends toward the outlet of the housing. And can be supported on the container part.

In addition, one end of the discharge line extends in the vertical direction and is located in the air collection area, and the other end of the discharge line penetrates through the upper end sidewall of the container and extends toward the outside of the container and may be supported by the container.

The filter device 1000 according to the present exemplary embodiment may further include a porous portion 1500 as shown in FIGS. 2, 3 and 5.

The porous portion 1500 is disposed in the air collection region 1150b. In this case, the porous part 1500 may be located inside the container part 1110 as shown in FIG. 2, and may be disposed in parallel with the water surface above the water surface.

A plurality of through holes 1500a are formed in the porous portion 1500. In this case, the plurality of through-holes 1500a may be formed by respectively penetrating the porous portion 1500 in the vertical direction.

For example, the porous portion 1500 may be provided as a plate member as shown in FIG. 5, but is not limited thereto.

The porous part 1500 may crush bubbles generated by air passing through the filtering region 1150a.

In more detail, air introduced into the inlet line 1200 may generate bubbles in the process of passing through the filtering region 1150a, that is, water contained in the main body 1100. The bubble moves upward and may move from the filtering area 1150a to the air collection area 1150b. In this process, bubbles may be collected in the filtering area 1150a by collecting some contaminants that are not collected in the filtering area 1150a but moving to the air collection area 1150b together with air.

At this time, the bubble passes through the plurality of through holes 1500a of the porous portion 1500 in the process of moving upward, and may be crushed into a plurality of relatively small bubbles (hereinafter, referred to as microbubbles).

The total surface area of the plurality of microbubbles formed by pulverization by the porous portion 1500 may be larger than the surface area of the bubbles before pulverization. In this case, the likelihood that the plurality of microbubbles come into contact with contaminants is increased rather than the bubbles before being pulverized, so that contaminants can be more effectively collected.

Accordingly, the filter device 1000 according to the present embodiment pulverizes the bubbles moving to the air collection area 1150b by the porous part 1500 into a number of small bubbles, and thus the filtering area using the plurality of small bubbles Some contaminants moving from 1150a to the air collection area 1150b may be effectively collected, and further, an effect of filtering contaminants flowing into the main body 1100 may be improved.

The porous portion 1500 may be disposed to have a predetermined interval with respect to the water surface. Here, the set interval is the interval between the bottom surface and the water surface of the porous portion 1500 at which the bubble moving to the air collection region 1150b can be crushed to the maximum, and may be determined through a number of simulations or numerical analysis. .

In this embodiment, the inlet line 1200 may extend through the porous portion 1500.

In this case, the coupling hole 1500b is formed through the porous portion 1500 as shown in FIG. 5, and the inlet line 1200 may pass through the coupling hole 1500b and extend to the filtering region 1150a.

For example, the porous part 1500 may be fixedly coupled to the inlet line 1200 passing through the coupling hole 1500b. At this time, the porous portion 1500 is fitted into the inlet line 1200 to form a set interval with respect to the water surface, and may be fixedly coupled by a method such as welding.

In this case, the porous portion 1500 can move inside or outside the container portion 1110 together with the inlet line 1200 supported by the lid portion 1120, so that management is easy and loss can be prevented.

In addition, although not shown, the porous portion may be coupled to the inlet line in various ways, such as detachably coupled to the inlet line.

Meanwhile, the porous portions 1501 ′ and 1502 ′ may be provided in plural as shown in FIG. 6. For reference, FIG. 6 is a view showing a modified example of the porous portion of FIG. 2, and in FIG. 6, the +Z-axis direction indicates an upward direction of the main body 1100.

The plurality of porous portions 1501 ′ and 1502 ′ may be spaced apart from each other in the extending direction of the inflow line 1200 ′ as shown in FIG. 6. In other words, the plurality of porous portions 1501 ′ and 1502 ′ may be spaced apart from each other in the vertical direction, that is, the extending direction of the main body 1100.

In this case, the through hole 1501a' of the porous portion 1501 ′ located on the side far from the water surface may be smaller than the through hole 1502a ′ of the porous portion 1502 ′ located on the side near the water surface. In this case, the bubbles moving to the air collection region 1150b pass through the plurality of porous portions 1501 ′ and 1502 ′ in sequence, and are pulverized into more fine bubbles, and contaminants may be more effectively collected.

For example, two porous portions 1501 ′ and 1502 ′ may be provided as shown in FIG. 6. The two porous portions 1501 ′ and 1502 ′ may be disposed to be spaced apart from each other in the vertical direction. At this time, of the two porous parts 1501 ′ and 1502 ′, the first porous part 1501 ′ may be located at a side far from the water surface, and the second second porous part 1502 ′ may be located at a side close to the water surface. have.

The number of porous portions 1501 ′ and 1502 ′ may be variously determined in consideration of the size of the inner space 1150 of the main body 1100.

The inlet line 1200 ′ may extend through the plurality of porous portions 1501 ′ and 1502 ′ in order. In this case, the inlet line 1200 ′ has a cross-sectional area reduced in a direction in which the plurality of porous portions 1501 ′ and 1502 ′ are spaced apart from each other, that is, in the vertical direction, and can penetrate the plurality of porous portions 1501 ′ and 1502 ′. have.

In other words, the inlet line 1200 ′ is provided in a multi-stage structure in which the cross-sectional area decreases as it passes through the porous part 1502 ′ located on the side closer to the water surface in the porous part 1501 ′ located on the far side to the water surface. Can be.

For example, in the inflow line 1200', a large area area 1200a' with the largest cross-sectional area is formed at the upper end of Fig. 6 and farthest from the water surface, and the large area area 1200a' is located below the large area area 1200a'. A first small area area 1200b' having a smaller cross-sectional area is formed, and a second small area area 1200c' having a smaller cross-sectional area than the first small area area 1200b' is formed under the first small area area 1200b'. ) Can be formed.

At this time, the first small area area 1200b' penetrates the first porous portion 1501', the second small area area 1200c' penetrates the second porous portion 1502', and the first porous portion A coupling hole (not shown) corresponding to the first small area area 1200b' is formed in 1501', and a coupling hole corresponding to the second small area area 1200c' is formed in the second porous portion 1502' (Not shown) can be formed.

In this case, the first porous portion 1501 ′ is supported on a step formed by the large area area 1200a ′ and the first small area area 1200b ′ and is prevented from moving to the large area area 1200a ′, The second porous portion 1502 ′ is supported on a step formed by the first small area area 1200b ′ and the second small area area 1200c ′ and is prevented from moving to the first small area area 1200b ′. I can.

Accordingly, the first porous portion 1501 ′ and the second porous portion 1502 ′ can be easily separated in the extending direction of the inflow line 1200, and the through hole 1501a ′ of the first porous portion 1501 ′ ) And the through hole 1502a' of the second porous portion 1502' may be prevented from contacting each other so that they are closed.

In FIG. 7, the +Z axis direction indicates the upper direction of the filter device 2000 and the main body 2100.

7 and 8, a filter device 2000 according to another embodiment of the present invention includes a main body 2100, an inlet line 2200, a discharge line 2300, and a porous part 2500, and water The pollutants introduced with the air can be filtered using.

The filter device 2000 according to the present embodiment differs from the previous embodiment in the structure of the inner space 2150 of the main body 2100. Hereinafter, in describing the present embodiment, differences from the previous embodiments will be described.

In this embodiment, the inner space 2150 of the main body 2100 may be divided into a plurality of small spaces 2151 and 2152 by the partition member 2600. In this case, filtering regions 2151a and 2152a and air collection regions 2151b and 2152b are formed in each of the small spaces 2151 and 2152.

For example, the inner space 2150 may be divided into two small spaces 2151 and 2152 by arranging a partition member 2600 in the central portion as shown in FIGS. 7 and 8. In this case, filtering regions 2151a and 2152a and air collection regions 2151b and 2152b may be formed in the two small spaces 2151 and 2152, respectively.

For reference, one of the two small spaces 2151 and 2152 is referred to as a first small space 2151 and the other is referred to as a second small space 2152. In this case, the filtering region 2151a and the air collection region 2151b formed in the first small space 2151 are referred to as a first filtering region 2151a and a first air collection region 2151b, respectively, and the second small space The filtering region 2152a and the air collecting region 2152b formed in the 2152 are referred to as a second filtering region 2152a and a second air collecting region 2152b, respectively.

However, this is only an example, and although not shown in other embodiments, it may be divided into three or more small spaces through a partition member.

The partition member 2600 may extend in an extension direction of the main body 2100 inside the main body 2100. In this case, the partition member 2600 may be supported on the inner wall of the main body 2100.

For example, the partition member 2600 may be provided in the form of a plate extending in the vertical direction as shown in FIG. 7. In this case, the partition member 2600 may extend from the bottom surface of the lid part 2120 to the bottom surface of the container part 2110.

The upper end of the partition member 2600 may be fixedly supported on the bottom surface of the lid part 2120 as shown in FIG. 7. In this case, the partition member 2600 is arranged to divide the inner space 2150 into two small spaces 2151 and 2152 when the lid part 2120 is coupled to the container part 2110, or the lid part 2120 When is separated from the container part 2110, the compartment for the inner space 2150 may be released.

The side end portion of the partition member 2600 may be supported on the inner wall of the container portion 2110 facing the side end portion of the partition member 2600 as shown in FIG. 8.

At this time, a pair of support protrusions 2700 may be formed on the inner wall of the container part 2110 to protrude toward the inside of the container part 2110. Each of the pair of support protrusions 2700 extends in the extension direction of the container part 2110 and may be spaced apart from each other in correspondence with the thickness direction of the partition member 2600 (eg, the X-axis direction as seen in FIG. 8 ). . In this case, the side end portion of the partition member 2600 may be inserted into the space between the pair of support protrusions 2700 and supported when the lid portion 2120 and the container portion 2110 are coupled.

A pair of support protrusions 2700 are the inner wall of the container part 2110 facing one end of the partition member 2600 and the container part 2110 facing the other end of the partition member 2600 as shown in FIG. Each may be formed on the inner wall. In this case, since both ends of the partition member 2600 are supported, shaking is prevented and can be effectively supported even when air and contaminants move inside the container unit 2110.

The lower end of the partition member 2600 may be supported by contacting the bottom surface of the container 2110 as shown in FIG. 7.

In this embodiment, contaminants introduced together with air may be collected through a plurality of small spaces 2151 and 2152 in sequence. In this case, among the plurality of small spaces 2151 and 2152, the air collection area 2151b of the small space 2151 of the previous order is a filtering area 2152a and the connection line 2800 of the small space 2151 of the next order. Can be connected.

Therefore, the filter apparatus 2000 according to the present embodiment can collect pollutants more effectively by sequentially collecting pollutants flowing into the inner space 2150 through a plurality of steps, thereby having an effect of filtering pollutants. It can be improved.

For example, one end of the inlet line 2200 is located in the first filtering region 2151a of the first small space 2151, and discharged to the second air collection region 2152b of the second small space 2152 One end of the line 2300 may be located.

The connection line 2800 is disposed in the second small space 2152 and extends, and a first small space 2151 and a second small space in an area corresponding to the first air collection area 2151b of the partition member 2600 A communication hole 2600a communicating with the 2152 may be formed through. At this time, one end of the connection line 2800 is connected to the communication hole 2600a and is connected to the first air collection region 2151b via the communication hole 2600a, and the other end of the connection line 2800 is subjected to second filtering. It may be located in the area 2152a.

In this case, the first filtering area 2151a of the first small space 2151 collects contaminants first, and the second filtering area 2152a of the second small space 2152 is next, that is, the last contamination. It can capture material.

In more detail, pollutants introduced together with air through the inlet line 2200 may be first introduced into the first filtering region 2151a and collected. Air and some pollutants that have passed through the first filtering region 2151a may be collected in the first air collection region 2151b.

Thereafter, air and pollutants collected in the first air collection region 2151b may flow into the second filtering region 2152a through the connection line 2800. In other words, the connection line 2800 may provide a path through which air and contaminants in the first air collection region 2151b move from the first air collection region 2151b to the second filtering region 2152a.

Pollutants introduced together with air through the connection line 2800 are collected in the second filtering area 2152a, and the air that has passed through the second filtering area 2152a is collected in the second air collection area 2152b. It may be discharged to the outside of the main body 2100 through the discharge line 2300.

Meanwhile, as shown in FIG. 7, each disturbing part 2400 may be formed at one end of the inflow line 2200 and the other end of the connection line 2800.

The porous part 2500 may be provided in the first small space 2151 and the second small space 2152, respectively, as shown in FIG. 7. In this case, the porous portion 2500 provided in the first small space 2151 is coupled to the inlet line 2200 in the first air collection region 2151b, and the porous portion provided in the second small space 2152 ( 2500 may be coupled to the connection line 2800 in the second air collection region 2152b.

Meanwhile, in another embodiment, a backflow prevention part 1900 may be formed in the air inflow line 1200 as shown in FIG. 9.

For reference, FIG. 9 is a view showing a state in which a backflow prevention part is installed in the air inflow line of FIG. 2, and in FIG. 9, a part of the air inflow line 1200 of FIG. 2 is enlarged.

The backflow prevention part 1900 may be installed inside the other end of the air inlet line 1200 toward the outlet of the housing (refer to 10 in FIG. 1 ).

The backflow prevention unit 1900 may prevent water contained in the main body (see 1100 of FIG. 2) from flowing back through the air inlet line 1200.

In more detail, the body containing water may fall by an external force in a state separated from the housing (see 10 in FIG. 1) of the cleaner (see 1 in FIG. 1) or in a state coupled to the housing. In this case, the water contained in the main body may flow back to the air inlet line 1200 and be discharged to the outside of the main body. Further, when the main body is coupled to the housing, the water contained in the main body flows backward and into the housing through the outlet of the housing. Can be introduced.

At this time, the backflow prevention unit 1900 closes the air inlet line 1200 to prevent the water contained in the main body from flowing backward, and water contained in the main body, especially water contaminated by pollutants, is discharged to the outside of the main body or the housing It can prevent inflow to the inside.

For example, the backflow prevention part 1900 may include an opening/closing member 1910, an elastic member 1920, and a stopper 1930.

The opening/closing member 1910 is provided in a plate shape and disposed inside the air inlet line 1200. In this case, the opening/closing member 1910 may have a cross-sectional area corresponding to the cross-sectional area of the air inflow line 1200.

The opening/closing member 1910 may be rotatably supported on the inner wall of the air inflow line 1200 at one end through the hinge shaft H. At this time, the opening/closing member 1910 may rotate around the hinge shaft H and open and close the air inlet line 1200.

In more detail, the opening and closing member 1910 may rotate in one direction around the hinge axis H as shown in FIG. 9 to open the air inlet line 1200. In this case, air and pollutants discharged from the outlet of the housing may be introduced into the air inlet line 1200.

Alternatively, the opening/closing member 1910 may rotate around the hinge axis H in another direction to close the air inflow line 1200 (see dotted line in FIG. 9 ). In this case, water accommodated in the main body may be prevented from flowing backward through the air inlet line 1200.

The elastic member 1920 elastically supports the opening and closing member 1910. In this case, the elastic member 1920 may expand and contract when the opening/closing member 1910 is opened/closed.

In more detail, air and pollutants may be introduced into the air inlet line 1200 from the outlet of the housing when the cleaner is operated. At this time, the opening/closing member 1910 is pressurized by the air introduced from the outlet to open the opening, and the elastic member 1920 may support the opening/closing member 1910 which contracts and opens.

Alternatively, air and pollutants may be stopped from flowing into the air inlet line 1200 from the outlet of the housing when the cleaner stops operating. At this time, the elastic member 1920 is elongated, and the opening/closing member 1910 is supported by the elongated elastic member 1920 to be closed. In other words, the opening/closing member 1910 may be closed by the elastic force of the elastic member 1920.

The elastic force of the elastic member 1920 may be determined in consideration of the vacuum pressure formed by the motor unit.

The elastic member 1920 may include a spring, but is not limited thereto.

The stopper 1930 supports the closing member 1910 in a closed operation. In this case, the stopper 1930 may protrude from the inner wall of the air inlet line 1200 and support the other end of the closing member 1910.

At this time, the stopper 1930 prevents the opening and closing member 1910 from opening the air inflow line 1200 by continuously rotating in the other direction during the closing operation by the elastic force of the elastic member 1920, and the opening and closing member 1910 ) Can maintain the closing operation.

In addition, although not shown, the backflow prevention unit may be provided in various structures capable of preventing backflow of water contained in the main body.

Meanwhile, although not shown in another embodiment, the porous portion may be detachably coupled to the inlet line.

For example, a male threaded portion may be formed on an outer wall of the inlet line, and a female threaded portion screwed with the male threaded portion of the inlet line may be formed on a sidewall forming a coupling hole of the porous portion. In this case, the porous portion moves upward when rotating in one direction and is coupled to the inlet line, and the porous portion moves downward when rotating in the other direction and may be separated from the inlet line.

Such a porous part moves up and down according to the amount of water injected into the container part, and the position of the inlet line can be adjusted.

In more detail, when the amount of water injected into the container is large, the water surface may rise. At this time, the porous portion may move upward with respect to the inflow line to form a set interval with respect to the water surface.

Alternatively, if the amount of water injected into the container is small, the water surface may be lowered. At this time, the porous portion may move downward with respect to the inflow line to form a set interval with respect to the water surface.

On the other hand, although not shown in the other embodiment, the position control portion may be formed on the bottom surface of the porous portion.

The position control unit may adjust the position of the inlet line of the porous portion corresponding to the rising water surface according to the amount of water injected into the container unit. In this case, the sidewall forming the coupling hole of the porous portion is spaced apart from the outer wall of the inlet line passing through the coupling hole of the porous portion, and the porous portion can be moved vertically with respect to the inlet line.

At this time, the porous portion may maintain a set interval with respect to the water surface even when the amount of water injected into the container portion is changed.

As an example, the position control unit may be provided in the form of a buoyancy body that forms buoyancy such as a rubber balloon.

In this case, the porous portion may float on the water surface due to the buoyancy of the position control portion. At this time, the porous portion is raised and lowered by buoyancy in response to the raised water surface and may maintain a set interval with respect to the water surface.

As another example, the position control unit may be provided in the form of a rod that can expand and contract in the vertical direction. In this case, a plurality of position control units may be provided, one end of each of the plurality of position control units supports the bottom surface of the porous unit, and the other end of each of the position control units may be supported on the bottom surface of the container unit.

In this case, the position control unit is elongated when the water surface rises, and the porous portion is supported by the elongating position control unit to move upward and maintain a set interval with respect to the rising water surface.

Alternatively, the position control unit may contract when the water surface descends, and the porous part may be supported by the contracting position control unit to move downward and maintain a set interval with respect to the descending water surface.

As described above, in this embodiment, when the filter device 1000 is coupled to the housing 10 of the cleaner 1 as shown in FIG. 1, the cleaner 1 collects pollutants that are sucked and discharged together with air. It has been described with an example.

However, this is only an example, and although not shown in other embodiments, a filter device is coupled to an air moving duct, which is a facility for ventilation, and collects pollutants that move along with the air along the air moving duct. Can be combined with equipment to trap contaminants.
