本発明はタバコ煙、浮遊じんあい等で汚れた空気を通過
させ、微細じんあい、においを除去する空気清浄用フィ
ルターに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air purifying filter that allows air contaminated with cigarette smoke, suspended dust, etc. to pass through and removes fine dust and odors.

掃により再使用できるが、装置が高価格化し高圧部を有
するため保守が容易でない。後者は圧力損失が大きい、
すなわち通気抵抗が大きいため送風機の大型化、運転音
が大きい等の欠点がめった。Conventionally, as air cleaners for this purpose, there have been either high-pressure charging, electrostatic precipitator cleaners with electrode plate precipitators, or pressure drop type mechanical precipitator metal repulsion air purifiers. The former can be reused by cleaning, but the equipment is expensive and has high pressure parts, making maintenance difficult. The latter has a large pressure loss,
In other words, the ventilation resistance is large, resulting in disadvantages such as the blower becoming larger and the operating noise being louder.
また微細じんあいの除去だけでは清浄効果として不十分
なため、一般に果しん部の波設フィルターとして脱臭用
活性炭フィルターが組付わされ′るが、この場合保守は

かる。In addition, since the removal of fine dust alone is not sufficient as a cleaning effect, a deodorizing activated carbon filter is generally installed as a corrugated filter in the fruit, but in this case, maintenance must be performed on both separately. It is troublesome for the user.

としたものである。The filter of the present invention uses an electret fiber layer filter for removing fine dust, which does not use a high-voltage power source and has a collection efficiency equivalent to that of electrostatic precipitator. For deodorization, we use an activated carbon fiber layer filter in which nonwoven fabric fibers are impregnated with finely powdered activated carbon. The pulverization of activated carbon increases the specific surface area of the activated carbon and has the effect of improving adsorption performance, and compared to using granular carbon alone, it is supported on open-cell nonwoven fabric, so it has a lower bulk density and less airflow resistance. This leads to the advantage that it can be small. The gist of the present invention is to use two types of filters having the above-mentioned features, sandwich the latter activated carbon fiber filter with the former electret fiber layer filter from the front and back, and bind the surrounding edges into a bag shape by heat sealing method etc. The structure is as follows.
本発明に係る一実施例を第1図から第5図で説明する。 One embodiment of the present invention will be described with reference to FIGS. 1 to 5.

化により判断できるものである。1 is an air purifying filter which is the essential part of the present invention. 2
is the air purifier body that circulates indoor air, 3 is the air outlet, 4
is a front cover having a suction port 5. Air circulation vanes 6 and an electric motor 7 are incorporated into the main body 2. The air purifying filter 1 faces the suction port 8 of the blade and is held in a dimensional relationship having a space 9 on the rear surface. The peripheral edge of the air purifying filter 1 is closed by a main body 2 and a front cover 4. When replacing the father, it can be easily done by disassembling the front cover 4 from the main body 2. The time to replace the filter can be determined by looking at the window 9 provided in the front cover 4 and checking the color change of the filter.

均一化の役目をしていることにある。Filter characteristics will be explained with reference to FIGS. 6 to 9. Figure 6 shows a 44-layer electret filter (thickness, a,
Fig. 7 shows a method (method A) in which the activated carbon fiber layer filter 12 is stacked on the latter stage of 10.11.
Electret fiber layer filter 10 from the front and rear surfaces of 2.
11 and the surrounding edges are bound by heat sealing method etc. (Method B). Comparing the characteristics of the two, as shown in Figures 8 and 9, the collection rate against the passing wind speed is The efficiency of method B is slightly lower than that of method A. on the other hand,
Since the electret fiber layer filter collects dust by forming an electrostatic field between the fibers, if the collection efficiency decreases as the dust is collected, the usage time (proportional to the amount of dust) and the collection time will increase. When examining the efficiency relationship, as shown in FIG. 9, the collection efficiency of method A is high initially, but as time passes, the relationship becomes reversed, with method B being higher. Therefore, method B has the advantage that the period in which the filter can be used, that is, the period when the filter can be replaced is longer. The difference in this characteristic is that in method A, the airflow surface where air impinges on the electret fiber layer is 1 + fB (P surface), whereas in method B, there are two surfaces (P and Q surfaces). Furthermore, the activated carbon fiber layer filter 12 has a rectifying effect to equalize the wind speed.
本発明によれば、ここでは活性炭繊維層フィルター12
がスペーサとなり組合せフィルターとしての利点を有す
るものである。 。According to the invention, here activated carbon fiber layer filter 12
serves as a spacer and has the advantage of being a combination filter. .
エレクトレット繊維層フィルター10の厚さaとエレク
トレット繊維層フィルター 11の厚さbは同一でなく
てもよいが、空気の流れ方向に対し組込時の方向性を選
ぶ必要が生ずる。同一であれば組込時の方向性がなく解
りやすい利点がある。Although the thickness a of the electret fiber layer filter 10 and the thickness b of the electret fiber layer filter 11 do not have to be the same, it is necessary to select the directionality at the time of assembly with respect to the air flow direction. If they are the same, there is no directionality when installing and there is an advantage that it is easy to understand.
生産性も標準化されて有利である。Productivity is also standardized and advantageous.

がある。したがって繊維の組合せ1体化の際、用いられ
る方法のニードルパンチング法は適切でない。Next, a drawback of the activated carbon fiber layer filter 12 is that, since finely powdered activated carbon is impregnated and supported on the nonwoven fibers of the base material, the activated carbon is brittle and falls off when rubbed or beaten. Therefore, the needle punching method used when combining the fibers into one is not appropriate.

な効果を上げることができる。Furthermore, the use of adhesive reduces the deodorizing ability, which is also not appropriate. In this regard, in the method of the present invention, the effective surface area of the activated carbon fiber filter 12 is simply overlapped, and the dimensions of the electret fiber layer filter 10.11 are made larger than the external dimensions of the activated carbon fiber layer filter 12 by the amount of the auricle. The sections are bound together using a heat seal method. Therefore, the electret fiber layer filter 10 does not mechanically destroy the activated carbon fiber layer filter 12 and takes advantage of its deodorizing performance to prevent the powdered activated carbon from falling off, which is its drawback.
11 is to be reinforced. This eliminates the need for a separate activated carbon cover. Also, in terms of maintenance, compared to replacing the fine dust and deodorizing filters separately, it is easier to maintain.
It can be handled only once at a time, and the structure of the air purifier main body 1 is simplified. Therefore, the basic effect of reducing near leakage can be achieved.
