向上や、冷暖房機器の普及に比例し高まってきている。[Detailed Description of the Invention] Industrial Application Fields Demands for dust collection and deodorization in general households are becoming stronger year by year. In particular, requests for the removal of cigarette odors, pet and toilet odors, etc. are increasing in proportion to improvements in the degree of airtightness of buildings and the spread of air conditioning equipment.
本発明はこのような要請に基づく空気清浄器に用いる空
気浄化用フィルタに関するものである。The present invention relates to an air purifying filter for use in an air purifier based on such requirements.

浄化性能を発揮しなくなるなどの欠点を有していた。BACKGROUND OF THE INVENTION The conventional method for this type of filter has been to simply fill a flat or zigzag filter case with granular adsorbent. This method has drawbacks such as the filling rate changes due to transportation, vibration, etc., the generation of fine powder and dirt, and the flow path of the processing fluid changes, making it no longer able to achieve its initial purification performance. .
また、これらの欠点を補うため、近年各種フィルタ加工

吸着能が低下したり、吸着剤の散布が不均一に成りやす
かったり、吸着剤の使用量を増やすと圧損が増加するな
どの欠点を有していた。Furthermore, in order to compensate for these drawbacks, various filter processing methods have been proposed in recent years. That is, as shown in FIG. 6, particles of adsorbent 320 are directly sprinkled on a thermoplastic resin nonwoven fabric 31 and bonded under heat to form a filter, or as shown in FIG. The adsorbent 32 is bonded to a nonwoven fabric, a three-dimensional mesh elastic sheet 33, etc. by selecting an adhesive such as the above adhesive. Of these, the former has drawbacks such as a weak bonding force between the adsorbent 32 and the nonwoven fabric 31, components attached to the adsorbent being altered by heat during heating, and high air pressure loss. The latter uses an adhesive, so the solvent and solute have a considerable effect on the adsorption capacity of the adsorbent.
This method has disadvantages such as reduced adsorption capacity, non-uniform distribution of the adsorbent, and increased pressure drop when the amount of adsorbent used increases.
そこで本発明者等は先に、上記のような欠点を解決する
空気浄化用フィルタを提案している。以下、その構成に

巣状接着シート９で接合している。Therefore, the present inventors have previously proposed an air purifying filter that solves the above-mentioned drawbacks. The configuration will be described below with reference to FIGS. 8 to 10. The honeycomb-shaped base material 34 is made of a thin aluminum plate or kraft paper hardened with a phenolic resin or the like. In this filter, an adsorbent 32 is placed in cells 35 of a honeycomb-shaped base material 34, and a nonwoven fabric 36 is bonded to one surface of the honeycomb-shaped base material 34 with a spider web-shaped adhesive sheet 9.

カム状基材は固いため、フィルタはフレキシブル性が乏
しく形状が限定されるという課題もあった。Problems to be Solved by the Invention However, in this filter, fine particles are usually included as the adsorbent 32 inside the filter, so the fiber basis weight of the nonwoven fabric 36 must be increased, resulting in high pressure loss. In addition, the pressure drop is relatively low for laminar air flow, but the pressure drop increases due to lateral flow and turbulent flow that occur in actual use as they collide with the honeycomb walls. Furthermore, since such a honeycomb-shaped base material is hard, there is also the problem that the filter has poor flexibility and its shape is limited.

It has a sexual septum 5. That is, one side of the three-dimensional knitted fabric 1 is closed with the mesh sheet 3 in a net shape. Here, the front and back polygonal mesh 2. The mesh sheet 3 was made of twisted polyester yarn, and the connecting yarn 4 was a single nylon yarn. The opening of the mesh sheet 3 was approximately 1.5 mm. The dimensions of a cell are generally expressed as 1 dimension and C dimension, and these 1 dimension and C dimension greatly affect the performance of the filter.

Therefore, the opening of the mesh sheet 3 on the back side of the three-dimensional knitted fabric 1 was set to about 0.5 mm. Moreover, a nonwoven fabric is used instead of the breathable sheet 8 of Example 1. Non-woven fabric is polyester,

/see, the pressure loss is 1 mmAq or less. Here, acrylic fibers that had been subjected to conductive treatment in advance were used as the mesh sheet 8 in order to serve as electrodes during electrostatic precipitation. The conductivity was set to IKΩ/C11 or less.

大きさにした。In the filter of the comparative example, the size of the kraft paper cells is 12 mm, the same as in Examples 1 and 2, and the thickness is 7 mm, and the adsorbent 36 is 6 mesh to 12 mesh (approximately 4 mm
2 mm) of four types of crushed charcoal, one for aldehydes, one for ammonia, one for sulfur compounds, and one for hydrocarbons, was used. - Also, the nonwoven fabric 36 is polyester, acrylic,
A fibrous nonwoven fabric made of thermoplastic resin such as PP or PE and having a basis weight of 30 g/j was used. The spider web-like adhesive sheet 9 was the same as in Examples 1 and 2, and the dimensions of the filter were 454 mm x 302 mm x about 7.5 mm thick.

などの繁殖を抑えることができる。The pressure drop was evaluated when the filter alone was measured in laminar flow at a flow rate of 1 m/sec, and when it was installed in the air purifier shown in Figures 4 and 5 and operated at a flow rate of approximately 0.4 m/sec. went. The results are as follows.As is clear from the results, the filters of the embodiments of the present invention all have lower pressure losses than the conventional filters of the comparative examples. Among them, Example 1 using granulated coal and reticulated sheet 8 has a low pressure loss. These effects are particularly noticeable when installed in air purifiers that generate turbulent flow. In addition, by applying antibacterial and antifungal treatment to each breathable sheet and three-dimensional knitted fabric, the growth of germs, bacteria, mold, etc. can be suppressed.

騒音で大風量の空気清浄機が可能となる。Effects of the Invention As is clear from the above embodiments, the present invention has a three-dimensional knitted fabric consisting of polygonal mesh cells with breathable partition walls as its core, so it is resistant to laminar and turbulent flows in actual use. A flexible air purifying filter with low pressure loss can be provided. Moreover, since it is flexible and has a net-like sheet integrally knitted on the back surface, it is possible to provide an air purifying filter with high shape retention. Therefore, the air purifying filter according to the present invention enables an air purifier with low noise and large air volume.
