Description

Air Fan with Air Cleaning Function and Filter Member Therefor

The present disclosure relates to a fan having an air purification function and a filter member therefor.

The content described in this section merely provides background information for the present disclosure and does not constitute the prior art.

In general, a fan used in a home or office is a machine that generates wind by electricity, and is a home appliance that is often used in hot summer.

Such a fan can provide cool wind to users in summer by rotating the rotor blades according to the driving of the motor and blowing air flowing in from the rear to the front side.

On the other hand, the demand for air purifiers (air purifiers) for purifying indoor air is rapidly increasing due to the emergence of fine dust or ultra-fine dust and the recent corona issue. There is a problem that the purchase cost of an air purifier is burdensome.

In addition, the air purifier is configured to suck air, purify the sucked air, and then discharge it. Therefore, when the air purifier strongly sucks air or does not strongly discharge the purified air, the discharged air is sucked back into the air purifier and the air purifying effect is reduced.

In order to solve this problem, the development of a fan having an air purifying function and a conventional blowing function at the same time at a relatively low cost is being actively developed.

For example, the prior art Registered Utility Model No. 20-0427342 (hereinafter, Utility Model Document 1) includes a mesh cloth that filters dust, etc., and a nonwoven fabric that filters small yellow dust, dust, etc. from the front of the mesh cloth and , a directional humidification filter disposed on the front surface of the nonwoven fabric is provided on the front surface of the fan to purify and humidify the air.

However, in the fan disclosed in Utility Model Document 1, serious frictional resistance is generated in the process of blowing the wind through the humidifying filter and the non-woven fabric and the mesh fabric, so the amount of purified air actually discharged is remarkably small. There is also a problem in that the blowing distance is also significantly shortened.

(Utility Model Document 1) Registered Utility Model No. 20-0427342 (published on September 19, 2006)

An object of the present disclosure is to provide a fan having an air purification function capable of simultaneously performing a conventional blowing function and an air purification function by disposing a filter member having a filter function on the rear surface of the fan.

1 is a front perspective view of a fan according to an embodiment of the present disclosure. 2 is a rear perspective view of a fan according to an embodiment of the present disclosure. For convenience of description, the filter member (see FIG. 4 ) is omitted in FIGS. 1 and 2 .

1 and 2 , the fan 100 according to an embodiment of the present disclosure may include a blade 110 and a housing 120 .

The blade 110 is configured to be rotatable through a motor. The blade 110 may include a hub connected to the drive shaft of the motor, and a plurality of blades extending radially from the hub.

The housing 120 may accommodate the blade 110 therein. The housing 120 may include a front protection net 122 and a rear protection net 124 disposed behind the front protection net 122 . The blade 110 may be disposed between the front protection net 122 and the rear protection net 124 .

The front protective net 122 is disposed to face the front of the blade 110 , and the rear protective net 124 is disposed to face the rear of the blade 110 . The front protection net 122 and the rear protection net 124 may serve to protect the user from the rotating blade 110 .

The fan 100 may further include a support unit 130 , a head unit 140 , and a pillar unit 150 .

The support unit 130 is configured to be in contact with the ground, and serves to support the fan 100 . The head unit 140 may be connected to the housing 120 , and may accommodate a motor for rotation of the blade 110 therein. The pillar 150 may support the blade 110 , the housing 120 , and/or the head 140 . One end of the pillar 150 may be rotatably connected to the head 140 , but the present disclosure is not limited thereto.

The fan 100 shown in FIGS. 1 and 2 is only an exemplary embodiment for convenience of description. Accordingly, the fan according to the present disclosure may have a shape or structure other than the embodiment shown in FIG. 1 .

3 is a view showing a state in which the head unit of the fan according to an embodiment of the present disclosure moves. In FIG. 3 , the filter member (see FIG. 4 ) is omitted for convenience of description.

Referring to FIG. 3 , the head unit 140 may be tilted vertically with respect to the pillar unit 150 . The tilting of the head unit 140 may be made to a range in which the blade 110 can see the ceiling. When the blade 110 faces the ceiling, the housing 120 may be in a state substantially perpendicular to the longitudinal direction of the column part 150 , that is, in a state parallel to the ground.

The tilting angle of the head 140 may be adjusted differently depending on the use of the fan 100 as well as the blowing direction of the fan 100 . For example, in the case of maximizing the air purification function, the head unit 140 may be completely tilted so that the blade 110 faces the ceiling or an angle close thereto. When the filter member (see FIG. 4 ) according to the present disclosure is mounted on the fan 100 in a state in which the blade 110 faces the ceiling or faces a similar angle, the air purification function can be maximized.

Referring back to FIG. 2 , the rear protection net 124 includes a plurality of first guard ribs 210 extending radially and at least one second guard rib 220 connecting the plurality of first guard ribs 210 . may include

The second guard rib 220 may include an inner guard rib 222 adjacent to the center of the rear guard net 124 and an outer guard rib 224 spaced apart from the center of the rear guard net 124 . However, the present disclosure is not limited thereto, and the second guard rib 220 may include only one of the inner guard rib 222 and the outer guard rib 224 .

Meanwhile, in FIG. 2 , the rear protection net 124 is illustrated as including both the first protection ribs 210 and the second protection ribs 220 , but the present disclosure is not limited thereto. For example, the back protection net 124 may include only the first protection ribs 210 without including the second protection ribs 220 . In this case, the hook coupling part (see FIG. 8 ) or the clip coupling part (see FIG. 10 ) of the filter member may have a structure or shape for coupling to the first protective rib 210 .

4 is a view showing a state in which the filter member according to an embodiment of the present disclosure is mounted on the fan.

5 is an exploded perspective view of a filter member mounted on a fan according to an embodiment of the present disclosure.

4 and 5 , the filter member 400 may include an activated carbon fabric 510 , a filter 520 , and a case 530 accommodating the filter 520 . The activated carbon fabric 510 , the filter 520 and the case 530 will be described later.

The filter member 400 may be disposed on the rear surface of the housing 120 . Accordingly, the air blown out from the blade 110 may proceed forward without obstruction of the filter member 400 , and the air may be discharged farther.

As a result, air circulation through the fan 100 can be made in a larger area, and the air purification effect can be further improved.

The filter member 400 may be detachably coupled to the rear protection net 124 . In this case, the filter member 400 may include a hook coupling part (refer to FIG. 8) and/or a clip coupling part (refer to FIG. 10) for detachably coupling to the rear protection net 124.

By configuring the filter member 400 to be detachably coupled to the fan 100 , the fan 100 according to the present disclosure may have a suitable driving state according to the surrounding conditions.

For example, when the fan 100 is used for a normal blowing function for providing cold air, the filter member 400 may be removed and the fan 100 may be used. Conversely, when the fan 100 is used to perform the air purification function as well as the blowing function, the fan 100 may be used after the filter member 400 is mounted on the rear surface of the housing 120 .

Meanwhile, in FIGS. 4 and 5 , the filter member 400 is detachably coupled to the rear surface of the housing 120 , but the present disclosure is not limited thereto. For example, the case 530 of the filter member 400 may be integrally formed with the rear surface of the housing 120 .

6 is a rear view of a fan equipped with a filter member according to an embodiment of the present disclosure.

Referring to FIG. 6 , at least one filter member 400 may be disposed on the rear surface of the housing 120 . For example, the at least one filter member 400 may be detachably coupled to the rear protection net 124 .

As shown in FIG. 6 , the two filter members 400 may be disposed on the rear surface of the housing 120 , but the present disclosure is not limited thereto. For example, one or three or more filter members 400 may be disposed on the rear surface of the housing 120 .

Each of the filter members 400 of the plurality of filter members 400 may have a shape of an outer light inner constriction. For example, the filter member 400 may have a sectoral shape in which a lower portion is partially removed. Through this, it is possible to prevent physical interference between the filter member 400 and the head unit 140 .

Meanwhile, in a state in which all the filter members 400 are disposed on the rear surface of the housing 120 , the filter member 400 may not be disposed in the lower region of the head unit 140 . Through this, when the head part 140 is tilted up and down, physical interference between the filter member 400 and the column part 150 can be prevented.

7 is a rear view of the fan from which the filter member is detached according to an embodiment of the present disclosure.

Referring to FIG. 7 , the rear surface of the housing 120 may include a first suction area 710 overlapping the filter member 400 and a second suction area 720 not overlapping the filter member 400 . .

At least some of the air sucked through the rotation of the blade 110 is configured to pass through the filter member 400 and the first suction region 710 , and at least another part of the air sucked through the rotation of the blade 110 is It is configured to pass through the second suction region 720 .

The first suction area 710 may be disposed adjacent to the central area of the rear surface of the housing 120 , and the second suction area 720 may be disposed spaced apart from the center area of the rear surface of the housing 120 .

If the filter is placed on the back of the housing, the flow of air entering the blade may be obstructed by the filter. In this case, since the amount of sucked air is reduced, the amount of discharged air may also be reduced. Accordingly, the air is discharged weakly, so that the range of air circulation may be narrowed, and as a result, the air purification effect may be reduced.

In this aspect, the fan 100 according to an embodiment of the present disclosure has a second suction area 720 that does not overlap with the filter member 400 as well as the first suction area 710 in which the filter member 400 is disposed. There is a technical feature in that the amount of air sucked can be additionally secured by arranging it around the first suction region 710 .

Accordingly, the air introduced through the first suction region 710 and purified by the filter member 400 may be discharged from the blade 110 together with the air introduced through the second suction region 720 . Since the air introduced through the first suction region 710 and the air introduced through the second suction region 720 are mixed, the discharged air may be discharged more strongly.

Accordingly, the fan 100 according to an embodiment of the present disclosure may have a wider air circulation range, and the air purification effect may also be improved. In addition, as the air is discharged more strongly, the original function of the fan 100, the blowing function, can also be improved.

On the other hand, in order to increase the amount of discharged air, the amount of air passing through the second suction region 720 is configured to be greater than the amount of air passing through the filter member 400 and the first suction region 710 . can

However, the present disclosure is not limited thereto, and the amount of air passing through the second suction region 720 is configured to be less than or equal to the amount of air passing through the filter member 400 and the first suction region 710 . can be

5 and 8 , the filter member 400 may include a filter 520 and a first filter case 810 accommodating the filter 520 .

The filter 520 may filter dust or bacteria contained in the sucked air. In this case, in order to reduce the filtering effect, a HEPA filter (High Efficiency Particulate Air, HEPA) may be used. A H13 filter may be used, but is not limited thereto.

The HEPA filter is made of electrified fiber, has strong adsorption power, and has excellent folding efficiency that removes 99.97% of polluting dust of 0.3 μm or larger, such as house dust, mites, viruses and mold, which are harmful to the human body.

However, the filter 520 according to the present disclosure is not limited to the HEPA filter, and other types of filters may be used. For example, to further enhance the filtering effect, an Ultra Low Penetration Air (ULPA) filter may be used. The Wolfa filter removes 99.99% of contaminant dust of 0.1 μm or larger, so it has better folding efficiency than the HEPA filter.

The cross-section of the filter 520 may have a shape in which a folded structure is repeated, such as a shape of 'VVVVVV'. However, the present disclosure is not limited thereto, and the filter 520 may have other cross-sections or structures.

In this case, the first opening 811 may be closed by the rear surface of the housing 120 while the filter member 400 is disposed on the rear surface of the housing 120 . Accordingly, the fan 100 according to an embodiment of the present disclosure has the effect of safely accommodating the filter 520 in the first filter case 810 without a separate cover member.

The filter member 400 may include a hook coupling part 820 configured to be hook-coupled to the rear protection net 124 .

The hook coupling part 820 may be configured to be hook-coupled to the second protective rib 220 . In this case, the hook coupling part 820 includes a first hook 822 hook-coupled to the inner guard rib (222, see FIG. 2) and a second hook 824 hook-coupled to the outer guard rib (224, see FIG. 2). ) may be included.

A hook coupling direction of the first hook 822 and a hook coupling direction of the second hook 824 may be opposite to each other. Accordingly, the protrusions formed on the first hook 822 may face the protrusions formed on the second hook 824 , or may face away from each other.

The filter member 400 may further include an activated carbon fabric 510 (refer to FIG. 4 ). The activated carbon fabric 510 has a function of removing harmful gases and odors in the air. Since the surface area of the carbon granules is large, the activated carbon fabric 510 has an advantage in that it is excellent in capturing gas passing through a conventional particle filter.

As shown in FIG. 4 , the activated carbon fabric 510 may be disposed between the rear surface of the housing 120 and the filter 520 , but the present disclosure is not limited thereto. it might be
