The present invention relates to a filter for a purifier, and more particularly, to a filter for a purifier that can increase the purification efficiency while considering the pressure loss rate.

In general, a purifier is composed of a suction fan, a suction port for suctioning indoor air by the suction fan, a discharge port for discharging the sucked air back to the room, and a filter for filtering contaminants from the air introduced in the air transfer path. .

Here, the filter has a variety of ways, the performance is also excellent by the development of filter manufacturing technology.

Such a filter is not used alone, but a structure for supporting and the like is used together.

Referring to FIG. 1, the filter unit 1 includes a support 2, a dust prevention nonwoven fabric 3 attached to the front and rear surfaces of the support 2, and an outer frame attached along the edge of the nonwoven fabric 3. 4) consists of.

At this time, the support 2 is manufactured in the form of a wire mesh with good air flow, and as shown in the detailed view, the air purification material 6 such as an adsorbent and a catalyst is attached to the net by the binder 5. The filter unit 1 is a pressure loss value is determined according to the network form of the support 2 caused a lot of inconvenience.

As another filter, a filter including an air purifying material such as an adsorbent or a catalyst in a predetermined thickness of a fabric is developed and used. This fabric filter has the advantage of easy processing because it does not attach the material to the net using a binder as in the conventional method.

However, the fabric filter has a tendency to improve the purification function due to the development of the material, but the pressure loss value is determined according to the thickness of the fabric filter has a disadvantage that the filter thickness should be used.

In other words, although the filter is getting better and thinner, the thicker filter has a higher purification efficiency, and it is natural to purify a larger amount of air, but I know that a thick, multi-ply filter is better, but Considering the loss rate, this situation is not available.

The present invention has been made to solve the above problems, an object of the present invention is to provide a filter for a cleaner that is used by making a plurality of perforations according to the pressure loss rate of the device after overlapping the filter in multiple layers.

The present invention to achieve the above object,

Provides a filter for a cleaner, characterized in that overlapping the fabric for air purification in multiple layers, perforated to penetrate a plurality of vent holes in the fabric, wrapped around the outside of the fabric in a non-woven fabric.

At this time, it is preferable that the air vent is perforated by heat fusion.

Hereinafter, a filter for a cleaner according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a perspective view showing a filter for a cleaner according to the present invention, Figure 3 is a cross-sectional view taken along the line A-A of FIG.

2 and 3, the filter 100 according to the present invention includes a fabric 110 and a nonwoven fabric 130.

Fabric 110 is a material for the air purification, as well as fabrics developed by our company may be used on the market. After cutting the fabric 110 by size, it overlaps several layers. At this time, the size of the fabric or the number of overlap is determined to match the performance of the cleaner to be used.

In this way, a plurality of vent holes 120 are perforated in the overlapped fabric 110. Ventilation 120 is the size and number of the diameter is changed according to the performance of the purifier.

4 is a graph of an example of experiments for the calculation of the size and number of perforations, basically, if the perforation rate is high, the pressure loss rate is lowered, and the pore rate and the pressure loss rate are inversely related.

In the graph of FIG. 4, NPT-H (4mm) has 28 holes and more perforations than NPT-H (6mm), and the perforation area ratio is substantially higher than the total area of the filter, but the pressure loss rate is lower. That is, it can be seen that the size of the perforation has a greater influence on the pressure loss rate than the perforation rate.

On the other hand, since the perforation hole 120 in the fabric 110 itself, heat sealing (Heating) is used to prevent the materials contained in the fabric 110 from leaking out.

This heat-sealed perforation, while preventing the outflow of the material while the fusion surface is perfect, it helps to strengthen the durability of the fabric.

In addition, when the heat-sealed perforation is bonded to each other by the heat-sealed fabrics overlapped with each other to help the bonding strength of the fabric.

The non-woven fabric 130 is finished on the outside of the perforated fabrics 110 in this way to seal. At this time, the non-woven fabric 130 is also used in consideration of the performance of the purifier, a suitable thickness so as not to lose pressure. The nonwoven fabric 130 prevents dust generated in the fabric from being emitted to the outside.

Hereinafter, the performance of the filter 100 for a purifier according to the present invention will be briefly examined.

The equipment for the performance test was patented by the company in 2006 No. 20302, which could not be measured by the existing small chamber method, but also for household and office furniture, home appliances, office equipment, household goods and large building materials, Technology that can suggest fundamental solutions to the problems of sick house syndrome and chemical hypersensitivity by conducting research and testing on the amount of harmful chemicals emitted from automobile interior materials in a state similar to the actual residential or spatial environment A system that provides the foundation.

Performance test conditions on the equipment,

1.chamber (air purification space): 1m ³

2. Initial concentration

formaldehyde 10ppm, ammonia 30ppm

3. analysis: GC-FID, NH ₃ -Detector

4. air flow: 4Nm ³ / min

5.temperature: 25 ℃

6.relative humidity: 30 ~ 40%

7. Filter size: 270mm ㅧ 90mm

The performance test results are shown graphically in FIGS. 5, 6 and 7.

5 is a graph showing the amount of formaldehyde (formaldehyde) per minute, it can be seen that the filter developed in our company (ecopro) has a superior purification ability than the filter of other companies (S company).

In other words, our filter shows a rapid decrease for about 5 minutes and formaldehyde is reduced by 60%. In about 10 minutes, it shows 80% of purification ability.

Figure 6 is a graph showing the amount of ammonia (ammonia) per minute, it can be seen that the filter developed in our company has a superior purification ability than the filters of other companies.

7 is a graph showing the pressure loss rate, and there is almost no pressure loss from the low speed (0.1 m / sec) to the high speed (0.4 m / sec).

As described above, the filter for a purifier according to the present invention has an excellent effect of using a thicker filter to increase the air purification capacity while considering the pressure loss rate according to the device.

That is, in the conventional filter products, since the consideration of the pressure loss rate is determined by the shape of the support network, the filter is a thin product having good air flow, while the filter according to the present invention has the diameter and number of perforated holes in the filter. Since the pressure loss rate is determined by the filter, the thickness of the filter can be thickened to maximize the air purification capacity and the purification amount.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. It will be appreciated.
