JP2000140533A - Filter for capturing/separating fine dust and capturing/ separating of fine dust using this filter - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable the easy capturing/separation of fine dust which can be the cause for allergy and contains a tick, a mildew and the like in a room by using a felt which shows the respective specific values of thickness and density as a filter to be mounted in the suction process of a suction device such as a vacuum cleaner. SOLUTION: A guide 1 is fitted to a pipe part in the suction process of a suction device such as a vacuum cleaner, and a filter 3 is mounted on the guide 1. The method for mounting the filter 3 is preferably to sandwich it between filters 2, 4 of nylon or the like having 10-70 mesh and 10-250 mesh, respectively. The filter 3 to be used is made of a felt with 1-3 mm thickness and 0.1-0.4 g/cm3 density. The felt material to be used is not particularly limited but is preferably a polyester needle punch felt. In the practical use application of the filter, the three filters 2-4 are, for example, fitted into the guide 1 and fixed with screws 5, 6, and further, the guide 1 is mounted on the pipe part in the suction process of the vacuum cleaner.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for cleaning house dust,
The present invention relates to a filter used for collecting and separating fine dust which may cause allergy including mites and molds, and a method for collecting and separating fine dust using the same.

[0002]

2. Description of the Related Art Conventionally, methods for collecting and separating fine dust include:
A filter is provided in the suction process of a suction device such as a vacuum cleaner, and a filter using a high-density fiber with a gap of 100 μm or less is used as the filter. A double three-layer structure in which two different types of nonwoven fabrics are stacked is used. A stack of a plurality of filters having different eye sizes (for example, 16 mesh and 200 mesh) (Japanese Patent Laid-Open No. 64-305
31) are known.

[0003]

However, in the above-mentioned method, the suction power of the vacuum cleaner is extremely lowered, which is not practical, and also places an excessive load on the motor of the vacuum cleaner. . On the other hand, in the method (1), although a reduction in the suction power of the vacuum cleaner can be avoided, there is a problem in that fine dust comes off and the filter is clogged.

[0004]

The inventors of the present invention have conducted intensive studies on a means for collecting and separating fine dust in house dust. As a result, a filter was provided in the suction process of a suction device such as a vacuum cleaner. , As its filter, thickness 1
It has been found that fine dust can be collected and separated very easily by using a felt having a density of 0.1 to 0.4 g / cm ^{3 and} a size of 0.1 to 0.4 mm, and the present invention has been completed. That is, the present invention has a thickness of 1 to 3 mm and a density of 0.1 to 0.4 g.
/ Cm ³ is a filter for collecting fine dust, which is preferably a needle-punched felt made of synthetic fiber such as polyester. It is.
In addition, the method is a method of collecting and separating fine dust using the filter, and is a method of collecting and separating the fine dust by attaching the filter to a pipe portion in a suction process of a suction device such as a vacuum cleaner. According to the present invention, by increasing the thickness of the filter portion, clogging of the filter due to fine dust can be reduced, and the load on the motor of the vacuum cleaner can be reduced. Further, since the negative charge of the synthetic fiber such as polyester attracts the positive charge of the dust, the fine dust can be adsorbed almost without missing.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a guide on a funnel as shown in FIGS. 1 and 2 is attached to a pipe portion in a suction process of a suction device such as a vacuum cleaner, and a filter of the present invention is attached thereto. As an example of use of the filter of the present invention,
It is preferable to mount the filter between the first 10-70 mesh filter made of nylon or the like and the last 10-250 mesh filter made of nylon or the like.
The filter of the present invention has a thickness of 1 to 3 mm and a density of 0.1 to
Consists of 0.4 g / cm ³ of felt. When the thickness is less than 1 mm, it is not preferable because a large amount of fine dust is removed.
If it exceeds m, the suction power is undesirably reduced. On the other hand, when the density is less than 0.1 g / cm ³ , it is not preferable because a large amount of fine dust is removed, and when the density exceeds 0.4 g / cm ³ , the suction power decreases, which is not preferable.
The felt material to be used is not particularly limited, but polyester needle punch felt is preferable. In the present invention, house dust containing fine dust that may cause allergies, such as mites and molds, is sucked by the above-mentioned vacuum cleaner or the like using such a filter. At this time, coarse dust is collected and separated on the first filter, and target fine dust is collected and separated on the filter of the present invention. The main purpose of the final filter is to hold the filter of the present invention.

[0006]

Next, the present invention will be described with reference to examples.
The present invention is not limited to these. The three filters 2, 3, and 4 shown in FIG. 2 (2: 10-70 mesh made of nylon, 3:
The filter of the present invention, 4: nylon 10-250 mesh) was fitted, fixed with screws 5 and 6, and then attached to the pipe part of the vacuuming process of the vacuum cleaner. In addition, as Comparative Example 1, a filter in which only two filters 2 and 4 were fitted, as Comparative Example 2, a filter in which a high-density fiber having a gap of 100 μm or less was fitted in place of the filter of the present invention in 3, and Comparative Example 3 Comparative Example 4 in which felt having a thickness of 0.5 mm (density 0.05 g / cm ³ ) was inserted instead of the filter of the present invention. As Comparative Example 4, the filter of the present invention 3 was replaced with a thickness of 4 mm (density of 0.5 g / cm ³ ). cm ³ ) felt, and the density of 0.05 g / cm ³ (thickness 0.5
mm) felt, 3 as Comparative Example 6
0.5g / cm density instead of the filter of the present invention
³ (thickness: 4 mm) was fitted with felt, fixed with screws 5 and 6, and each was attached to a pipe part of a suction process of a vacuum cleaner. Fine dust (approximately 50 μm or less) sampled in advance and sifted through a 200 mesh sieve was used as test dust, and 1 g of the dust was spread evenly on 1 m ² of the floor, followed by suction with the vacuum cleaner for 20 seconds.
The same applies to Comparative Examples 1 and 2. As a result, Table 1
As shown in the figure, when the filter of the present invention was used, the fine dust collection rate was 80%, but when Comparative Example 1 was used, the fine dust collection rate was 10%. When the filter of Comparative Example 2 was used, no suction was performed. Comparative Example 3 and Comparative Example 5 were the same, and the fine dust collection rate was 40% or less. Comparative Example 4 and Comparative Example 6 were the same, and the collection rate of fine dust could not be measured because the suction force was extremely reduced.
