Description

Air Purifier {AIR PURIFIER}

The present invention relates to an air purifier, and more particularly to a so-called cylindrical air purifier.

Cylindrical air purifiers often have a structure in which air is sucked into the interior from the outside through a circumferential surface and purified, and then discharged back through the upper surface. Therefore, since air is sucked in at 360°, there is an advantage of covering various directions.

However, when such a cylindrical air purifier is installed adjacent to a wall or corner, the air is sucked at a constant flow rate even though the wall or corner side has a relatively low need to purify the air compared to the side where the user is mainly active. There is a problem that the overall efficiency is lowered.

The present invention provides an air purifier capable of improving efficiency.

In addition, it provides an air purifier that can prevent the fine particles of activated carbon to be discharged to the outside.

It also provides an air purifier that allows the user to easily assemble/disassemble the pre-filter.

The air purifier according to the present invention is a filter assembly formed in a tubular shape, a frame formed in an annular shape and disposed on the outside of the filter assembly, extending in the longitudinal direction of the filter assembly and being rotatably coupled to each other in the frame A plurality of shafts, a louver and air rotatable through the filter assembly passing through the filter assembly passing through the filter assembly to an open position to open a space between two adjacent shafts among the plurality of shafts and a closed position to close the space It may include a fan to force.

In addition, further comprising a sensor for directing a specific direction and sensing an object, when the sensor detects an object, a shaft located in the specific direction among the plurality of shafts may rotate to a closed position.

In addition, further comprising a first sensor pointing to the first direction and sensing the object and a second sensor pointing to the second direction and sensing the object, when the first sensor detects the object, the first of the plurality of shafts When the first shaft positioned in the direction rotates to the closed position, and the second sensor detects an object, the second shaft located in the second direction among the plurality of shafts may rotate to the closed position.

In addition, when all sensors detect an object, the user may be notified that the air cleaner is blocked.

In addition, the plurality of shafts are divided into a first group and a second group, and the first shafts belonging to the first group rotate in cooperation with each other by a first gear, and the second shafts belonging to the second group are second gears. Can rotate in conjunction with each other.

In addition, it may further include a first motor connected to the rotating shaft of any one of the first shafts to drive the shaft and a second motor connected to the rotating shaft of any one of the second shafts to drive the shaft. .

In addition, the first gear and the second gear may have a height difference.

In addition, the filter assembly is formed in a tubular shape and includes a deodorizing filter having activated carbon and a hepa filter formed in a tubular shape having a diameter smaller than that of the deodorizing filter and disposed inside the deodorizing filter. It can be forced to suck air through the circumferential surface.

In addition, it is formed in a cylindrical shape, a hole for air passing is formed on the circumferential surface, and a case and a tubular shape are formed on the inner circumferential surface with a guide along the longitudinal direction, disposed inside the case, and a guide corresponding to the guide of the case on the outer circumferential surface. Further comprising a pre-filter is formed, the pre-filter can be detachably coupled to the case in a downward slide along the guide from the upper side of the case.

In addition, the upper end of the case is provided with a magnet, it is formed in an annular shape is disposed on the upper side of the pre-filter from the inside of the case, but further comprising a fixing ring having a material having a magnetic attraction to the magnet of the case, The fixing ring can be attached to the top of the case by magnetism.

The air purifier according to the present invention can improve the efficiency of the air purifier by reducing unnecessary operation by rotating the shaft and the louver in the corresponding direction when the sensor senses the wall.

In addition, when the air is sucked and purified and then discharged, the deodorizing filter having a pellet-type activated carbon is located upstream on the flow path of the air rather than the HEPA filter, so that even if fine particles of activated carbon are generated from the deodorizing filter, the fine particles are HEPA filters By filtering it can be prevented from being discharged to the outside.

In addition, the pre-filter is detachably coupled to the case downwardly along the guide from the upper side of the case and slided, and the retaining ring is attached to the top of the case by magnetism, thereby preventing the pre-filter from disengaging upward from the case. On the other hand, it can be easily assembled/disassembled by the user, and durability can be improved.

Referring to the drawings will be described in detail with respect to the air purifier 100 according to an embodiment of the present invention.

It is shown. 3 is a longitudinal sectional view taken along line A-A in FIG. 1, and FIG. 4 is a cross-sectional view taken along line B-B in FIG.

5 is a perspective view of the shaft 122 of the air purifier 100 according to an embodiment of the present invention, and FIG. 6 is an enlarged view of part C of FIG. 5.

Referring to Figures 1 to 4, the air purifier 100 is entirely cylindrical, and after the air is sucked and purified from the outside through the circumferential surface of the air purifier 100, the air purifier 100 is external to the outside through the upper surface of the air purifier 100 again. It has a structure that is discharged. Alternatively, in some cases, air may be sucked into the interior from the outside through the upper surface of the air cleaner 100 and purified, and then discharged to the outside through the circumferential surface of the air cleaner 100. However, hereinafter, for convenience, the air purifier 100 will be uniformly described as having an electron structure.

The air purifier 100 includes a filter assembly 110, a flow path control assembly 120 and a housing assembly 130.

Of course, the air purifier 100 further includes a fan (not shown) for forcing air to pass through the filter assembly 110 (not shown), a cover (not shown) having a discharge port, and the like. However, these components themselves are already known, and a person skilled in the art can easily design them by considering the characteristics of the filter assembly 110, the flow path control assembly 120, and the housing assembly 130 below. Description is omitted.

The filter assembly 110 is generally formed in a tubular shape, and air is purified as it passes through the circumferential surface of the filter assembly 110.

The filter assembly 110 may be combined with different types of filters. For example, the filter assembly 110 may include a pellet-type activated carbon and include a deodorizing filter 111 for removing odor or harmful gas, a hepa filter 112 for removing fine dust or bacteria, and the like.

In this case, the deodorizing filter 111 is formed in a tubular shape having a specific inner diameter, and the hepa filter 112 is formed in a tubular shape having an outer diameter substantially equal to or slightly smaller than the inner diameter of the deodorizing filter 111, and thus the deodorizing filter 111 It is arranged coaxially inside.

According to this, when the air passes through the circumferential surface of the filter assembly 110, it passes through the deodorizing filter 111 and then passes through the HEPA filter 112. Therefore, even if fine particles of activated carbon are generated from the deodorizing filter 111, it can be prevented that the fine particles are filtered by the HEPA filter 112 and discharged to the outside.

5 and 6, the flow path control assembly 120 includes a frame 121, a shaft 122, and a louver 123.

The frame 121 is formed in an annular shape having a larger diameter than the filter assembly 110, and is disposed coaxially on the upper and lower sides of the filter assembly 110.

The shaft 122 extends in the longitudinal direction of the filter assembly 110. In addition, a plurality of shafts 122 are provided and are spaced apart from each other along the circumferential direction of the filter assembly 110. In other words, the shafts 122 are vertically arranged in the frame 121 and are spaced apart from each other.

Further, the shaft 122 is rotatably coupled to the frame 121, respectively.

The louver 123 is formed in a plate shape having a width corresponding to the distance between two adjacent shafts 122. Accordingly, the louvers 123 are coupled to the shafts 122 and rotate together to selectively open and close the space between two adjacent shafts 122.

Specifically, the louver 123 may open a space between two adjacent shafts 122 by rotating the plate surface side by side in the radial direction of the filter assembly 110. Hereinafter, the position is referred to as an "open position".

On the other hand, by rotating the plate surface in parallel to the circumferential direction of the filter assembly 110 or its tangential direction, it is possible to close the space between two adjacent shafts 122. Hereinafter, the position is referred to as a "closed position".

Moreover, the shaft 122 and the louver 123 may be divided into a plurality of groups. For example, in a cross-sectional view, it can be divided into a first group corresponding to one semicircle side and a second group corresponding to the other semicircle side. Of course, it may be further divided into a third group, a fourth group, a fifth group, and the like, but hereinafter, it will be described as being divided into two groups for convenience.

In addition, hereinafter, any one of the semicircle sides with respect to the center is referred to as a "first direction", and a shaft and a louver located in the first direction, that is, a shaft and a louver belonging to the first group are referred to as "first shaft 122-1". And "First Louver (123-1)". Similarly, the other semicircle side with respect to the center is referred to as the "second direction", and the shafts and louvers located in the second direction, that is, shafts and louvers belonging to the second group are referred to as "second shafts 122-2" and " The second louver (123-2)".

In this case, the first shaft 122-1 rotates in cooperation with each other by the first gear 124-2, and the second shaft 122-2 rotates in cooperation with each other by the second gear 124-2. can do.

Accordingly, the first motor 125-1 is coupled to the central axis of any one of the first shafts 122-1 to drive the shaft, so that the first shafts 122-1 all rotate at the same time, and the second shaft The second motor 125-2 is coupled to the central axis of one of the shafts 122-2 to drive the shaft, so that the second shaft 122-2 can all rotate at the same time. In addition, the first shaft 122-1 and the second shaft 122-2 can be controlled independently.

The first gear 124-1 and the second gear 124-2 may have a height difference as shown in FIG. 6 to prevent mutual interference.

The housing assembly 130 includes a case 131, a pre-filter 132, a fixing ring 133, and a sensor S.

The case 131 is formed in a substantially cylindrical shape to surround the filter assembly 110 and the flow path control assembly 120.

A hole 131A for air to pass through is formed on the circumferential surface of the case 131.

In addition, a guide 131B is formed on the inner circumferential surface of the case 131, which extends in the longitudinal direction and is spaced apart from each other along the circumferential direction.

Furthermore, the case 131 is provided with a magnet 131C at the top.

The pre-filter 132 is formed in a tubular shape having an outer diameter substantially equal to or slightly smaller than the inner diameter of the case 131 and coaxially disposed inside the case 131.

A guide 132A corresponding to the guide 131B of the case 131 is formed on the outer circumferential surface of the pre-filter 132. Therefore, the pre-filter 132 may be detachably coupled to the case 131 in a sliding manner downward along the guides 131B and 132A from the upper side of the case 131.

On the other hand, the pre-filter 132 may be formed lower than the case 131, the fixing ring 133 is formed in an annular shape having an outer diameter substantially equal to or slightly smaller than the inner diameter of the case 131, the case 131 of It is arranged coaxially on the upper side of the pre-filter 132 from the inside.

The retaining ring 133 is provided with a magnet 133A to which magnetic attraction acts on the magnet 131C of the case 131. Therefore, the fixing ring 133 is attached to the upper end of the case 131 by magnetism, so that the pre-filter 132 can be prevented from deviating upward from the case 131.

Of course, for this purpose, only one of the upper end of the case 131 and the retaining ring 133 may be provided with a permanent magnet, and the other may be provided with a conductive material such as an iron plate.

A plurality of sensors S are provided, and are arranged to be spaced apart from each other along the circumferential direction of the case 131, and radially directs different directions and senses an object.

More specifically, it may include a first sensor (S-1) pointing in the first direction and a second sensor (S-2) pointing in the second direction.

Based on the configuration of the air cleaner 100 described above, the assembly/disassembly of the air cleaner 100 will be described below.

First, in order to assemble the filter assembly 110, the HEPA filter 112 is inserted into the deodorizing filter 111.

According to this, as described above, when the air is sucked into the interior from the outside through the circumferential surface of the air purifier 100 and purified, and then discharged again through the upper surface of the air purifier 100, the deodorizing filter 111 It is located upstream of the air passage than the HEPA filter 112. Therefore, even if fine particles of activated carbon are generated from the deodorizing filter 111, it can be prevented that the fine particles are filtered by the HEPA filter 112 and discharged to the outside.

In addition, the pre-filter 132 is inserted into the case 131 to assemble the housing assembly 130.

At this time, since the pre-filter 132 can be coupled to the case 131 in a downward manner along the guides 131B and 132A from the upper side of the case 131, the user will be able to assemble more easily.

Next, a fixing ring 133 is installed on the upper side of the pre-filter 132.

At this time, since the fixing ring 133 is naturally attached to the top of the case 131 by magnetism, the user can more easily assemble it.

Moreover, it is preferable that the pre-filter 132 is usually disassembled or washed once or twice a month. Since the pre-filter 132 needs to be frequently assembled/disassembled as described above, if the pre-filter 132 is fixed to the case 131 by a conventional mechanical fastening method, such as a protrusion and a groove or an interference fit, the corresponding part is assembled/disassembled. There is a problem that the corresponding part can be easily broken as it is used for a long time due to the stress acting on it and its fatigue accumulation. On the other hand, the air purifier 100 can effectively prevent the above problem by using the magnets 131B and 133A.

Hereinafter, the operation of the air cleaner 100 will be described.

First, when the air cleaner 100 is operated, the shaft 122 and the louver 123 rotate to an open position as shown in FIGS. 7A and 7B. Therefore, air is sucked from the outside through the space between the hole 131A of the case 131 and the adjacent two shafts 122 and purified by the filter assembly 110 and then discharged again through the discharge port. have.

Conversely, when the air purifier 100 stops working, the shaft 122 and the louver 123 rotate to the closed position as shown in FIGS. 8A and 8B. Therefore, air cannot pass through the space between two adjacent shafts 122.

On the other hand, when the air purifier 100 is installed adjacent to a wall or corner, the need to purify the air may be relatively low on the wall or corner side compared to the side in which the user is mainly active. Therefore, when the sensor S detects an object, that is, a wall, the shaft 122 and the louver 123 in the corresponding direction rotate to a closed position or an intermediate position between the open position and the closed position.

Specifically, for example, as illustrated in FIGS. 9A and 9B, when the first sensor S-1 senses a wall, the first shaft 122-1 and the first louver 123-1 are in a closed position or in the middle thereof. It rotates to the position, and the second shaft 122-2 and the second louver 123-2 rotate to the open position. Therefore, the air is not introduced from the first direction in which the necessity to purify the air is relatively low, and air is intensively introduced and purified only in the second direction in which the necessity to purify the air is concentrated, thereby improving the efficiency of the air purifier 100. Can improve.

Furthermore, if the first sensor S-1 and the second sensor S-2 detect an object at the same time, the user may notify the user to move the air purifier 100 to an appropriate space because the periphery of the air purifier 100 is blocked.

The air cleaner 100 described above is only one of the air cleaners according to various embodiments of the present invention.

For example, the air purifier according to another embodiment of the present invention further includes a sensor for detecting the illuminance, and if the illuminance is greater than or equal to a predetermined value, the user determines the time zone during which the user is active, and the shaft and louver rotate to the open position, and the illuminance is preset If the value is less than a predetermined value, the user may determine that the time is inactive, and the shaft and the louver may rotate to a closed position or an intermediate position.

As described above, the technical spirit of the present invention is not limited to the above embodiments, and as described in the claims, there will be a technical spirit to the extent that a person having ordinary knowledge in the technical field to which the present invention pertains can easily change.
