Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can purify indoor air, and in particular, places where dust tends to accumulate, such as corners of rooms, the back of furniture and home appliances, and other places where clean air is preferred. And a small air purifier capable of supplying clean air.

[0002]

2. Description of the Related Art An air purifier for purifying indoor air is conventionally known. However, there is no known air cleaner that supplies clean air directly to a place where clean air is preferred.

An object of the present invention is to provide a small-sized air purifier capable of purifying indoor air and supplying clean air directly to a place where clean air is preferred. .

[0004]

According to the first aspect of the present invention,
An air purifier characterized in that a bag-shaped filter is detachably attached to an air outlet of a fan body so as to close the air outlet.

According to a second aspect of the present invention, in the first aspect of the invention, the filter can be washed and reused.

According to a third aspect of the present invention, in the first aspect of the invention, a dust adsorbent is applied to an inner surface of the filter.

[0007]

FIG. 1 is a longitudinal sectional view of an air purifier according to the present invention. The air purifier 1 includes an axial fan body 2.
And a filter 3. The fan body 2
As shown by an arrow, air is sucked from the suction port 21 and sent out from the outlet 22 on the opposite side. The outlet 22 of the fan body 2 protrudes in a cylindrical shape, and has a flange 221 at the tip.

The filter 3 has a bag shape and is made of a material which is breathable but has fine eyes. The size of the eyes is set smaller than the dust to be collected. The filter 3 can be washed and reused. Further, a dust adsorbent is applied to the inner surface of the filter 3.

The filter 3 is detachably attached to the outlet 22 of the fan main body 2 so as to cover the outlet 22 by externally fitting the opening of the filter 3 to the cylindrical outlet 22 and fastening it with the rubber band 4. ing. At this time, the flange 221 prevents the rubber band 4 from shifting.

When the air cleaner 1 having the above configuration is operated,
In the fan body 2, air is sucked in from the inlet 21 and sent out from the outlet 22, as indicated by the arrow. Then, the sent air enters the filter 3, passes through the filter 3, and is sent out of the filter 3 from the entire peripheral surface of the filter 3, as shown by the arrow. At this time, dust in the air is removed by the filter 3 when the air passes through the filter 3, and adheres to the inner surface of the filter 3. Therefore, according to the air purifier 1, the air is sucked in from the suction port 21 and purified, and then sent out from the entire peripheral surface of the filter 3. Thereby, the indoor air is purified.

The dust is adsorbed and held on the inner surface of the filter 3 by a dust adsorbent. For this reason, the dust is efficiently removed by the filter 3, and the dust does not fly in the filter 3. Therefore, from this point, the dust is efficiently removed by the filter 3. Therefore, the cleaning efficiency of the air purifier 1 is improved. Furthermore, since dust adheres to the inner surface of the filter 3,
The appearance of the air purifier 1 is not covered with dust due to adhesion of dirt, and it is not difficult to see.

Further, since the filter 3 can be washed and reused, the filter 3 always exhibits stable dust removal efficiency by being used after washing.
In addition, by reusing the filter 3, the economy of the air purifier 1 is improved.

FIG. 2 is a plan view showing an example of a use form of the air cleaner 1. Here, the air purifier 1 is installed with the filter 3 inserted into the gap 7 between the television 5 and the wall 6. The filter 3 is formed in a curved shape in plan view. According to this use mode, since the purified air is sent from the entire peripheral surface of the filter 3 as shown by the arrow, the clean air is always supplied to the gap 7 between the television 5 and the wall 6 where dust easily accumulates. Since air is supplied, accumulation of dust in the gap 7 is prevented. Therefore, a fire accident such as tracking due to the adhesion of dust is prevented.

The mode of use is not limited to the case shown in FIG. 2. For example, the filter 3 may be arranged at the bedside of the bed, whereby clean air is always supplied to the sleeping person. And sleep comfort is improved.

The fan body 2 is not limited to an axial fan, but may be a sirocco fan.

[0016]

According to the first aspect of the present invention, the air sucked by the fan body can be cleaned by passing through the filter, so that the indoor air can be cleaned. In addition, since the bag-shaped filter can be placed in any place as an arbitrary shape, it can be placed in any corner, such as a corner of the room, the back of furniture or home appliances, or other places where clean air is preferred. Can be supplied with clean air. Therefore, it is possible to prevent dust from accumulating in a place where dust easily accumulates, to construct a comfortable living space, and to prevent a fire accident such as tracking.

According to the second aspect of the present invention, by using the filter after cleaning, the dust removing efficiency can be constantly exhibited, and therefore, the cleaning efficiency of the air purifier can be maintained at a stable level. In addition, the economy of the air purifier can be improved by reusing the filter.

According to the third aspect of the present invention, since dust can be adsorbed and held on the inner surface of the filter, the efficiency of dust removal by the filter can be improved. In addition, since the dust can be prevented from flying inside the filter, the efficiency of dust removal by the filter can be improved from this point as well. Therefore,
The cleaning efficiency of the air purifier can be improved.
