に、取り扱いも容易となる。As filters for air purifiers, pleated corrugated filter material is used in order to increase the dust holding capacity and improve the dust trapping ability by slowing the passing wind speed. Additionally, a filter material made of activated carbon or the like is used for deodorization. In addition, if the filter material for dust removal and the filter material for deodorization are installed separately, the installation space for the filter material will become larger and the effort to replace it will also increase. In addition, Japanese Patent Application Laid-Open No. 60-58227 proposes a single filter by inserting deodorizing filter material such as activated carbon into the valleys of a corrugated filter material. ing. in this case,
Not only does the space for installing the filter inside the air purifier become smaller, but it also becomes easier to handle.

In other words, since the deodorizing filter material is granular like activated carbon, it is not possible to fill the troughs of the corrugated dust removing filter material with the granular deodorizing filter material. Fine powder may be generated due to the movement of the filter material,
If the deodorizing filter material is uneven, some air may pass through the filter without being deodorized, resulting in poor deodorizing effect, and variations in filter pressure drop may affect the noise of the blower. Relaxing. The partition plate 6 formed by combining two types of plates 6a and 6b in a lattice shape as shown in FIG.
As shown in FIGS. 1 to 18, the part 1 of the corrugated dust removal filter is housed in a rectangular frame 3, and the troughs of the part 1 of the dust removal filter are divided into a plurality of parts by partition plates 6, and It is possible to insert part of the granular deodorizing filter 2 into this divided area, but in this case, it is necessary to prepare a partition plate 6 as a separate part, which is extremely difficult and costly in terms of manufacturing. It's also expensive. Moreover, since the partition plate 6 closes a part of the suction surface, the suction efficiency is also deteriorated. The present invention has been made in view of these points, and its purpose is to provide the advantages of integrating a dust removal filter material and a deodorizing filter material, as well as to solve the above-mentioned problems associated with this integration. To provide a filter for an air purifier in which problems are solved.

木鉢型の空気清浄器を示している。Therefore, the present invention provides a dust removal filter material having air permeability in the form of a corrugated plate, a granular deodorizing filter material that is filled into the valley space on one side of the dust removal filter material, and a dust removal filter material. A cover made of a breathable sheet that is fixed to the top of the peak on one side of the material and covers the deodorizing filter material, the dust removing filter is attached to the part of the deodorizing filter side of the dust removing filter material. The first feature is that the ribs in the direction that intersect the ridgeline of the mountain part of the filter material are formed by adding hot melt material. is disposed on the one surface side of the dust removal filter material, and the end portion of the conductor is exposed to the outer surface and serves as a terminal portion. [Function] According to the first feature of the present invention, the ribs formed by adding hot melt material to the dust removal filter material prevent the movement of the granular deodorizing filter material, According to the second feature, the presence of the terminal portion facilitates electrical connection, and it is possible to reliably use the conductor as a ground electrode when performing electrostatic precipitate collection. [Example] The present invention will be described in detail based on the illustrated example below.
Figures 3 to 3 show a first embodiment, and this filter is composed of a rectangular frame 3, a part 1 of the dust removal filter, a part 2 of the deodorizing filter, and a cover material 4. It has become something that has been done. Part 1 of the dust removal filter is called a fiber filter made of non-woven fabric such as polypropylene fiber or polyester fiber, and this part of the filter is capable of attaching ultrafine particles down to the micron level to the fiber surface. 1 is bent into a corrugated plate shape in order to increase the filtration area and slow down the passing wind speed. The part 1 of the dust removal filter whose peripheral edge is adhered to the inner surface of the frame 3 to prevent air leakage is provided with a plurality of ribs 10 made of hot melt material on one side thereof. These ribs 10, which are formed in a direction that intersects the ridgeline of the peak of the filter part 1, which is shaped like a corrugated plate, and are interrupted at the bottom of the valley, are used to increase the filtration area. The problem that when the bending pitch P is reduced, adjacent peaks come into close contact with each other and pressure loss increases is prevented by bringing ribs 10 on adjacent peaks into contact with each other. The deodorizing filter part 2 is made of granular activated carbon, and is evenly filled in the troughs of the corrugated filter part 1. A cover 4 is a breathable sheet made of non-woven fabric.
is attached to one side of the frame 3. The cover 4 is attached to the top of the rib 10 made of hot melt material using a hot press. When the filter formed in this way is attached to an air purifier, the air flow is in the direction shown by the arrow in FIG. It is brought into contact with the odor filter material 2. Here, the granular deodorizing filter material 2 used has a particle size that cannot easily pass between the opposing ribs 10. In other words, the bending pitch P of the filter material 1 and the height of the ribs 10 are selected depending on the particle size of the deodorizing filter material 2 to be used. Therefore, the granular deodorizing filter material 2 is prevented from moving by the ribs 10, and furthermore, the ribs 10 are prevented by adhering the hot melt material to the dust removing filter material 1, and are made into separate parts. Compared to assembling partition plates, the cost is lower and the finished product is much more compact. As shown in FIG.
may also be provided on the opposite side of the filter material 2. In this case, in order to prevent the filter material 1 from swelling to the opposite side when filling the deodorizing filter material 2, it is possible to hold the filter material 2. can be performed in a more stable state. In adhering and fixing the cover 4, as shown in FIGS. 5 and 6, hot pressing may be performed using a coarse adhesive sheet 30 made of polyamide and having a low pressure loss type. In this case, the cover 4 is fixed not only at the top of each rib 10 but also at the ridgeline of the peak of the filter material 1, so that particulate matter is not fixed through the gap between the filter material 1 and the cover 4. Not only can movement of the deodorizing filter material 2 be eliminated, but also unevenness in pressure loss can be eliminated. The embodiments shown in FIGS. 7 to 9 are of a type used in an electric S seat type air purifier. As shown in Fig. 20, the electrostatic precipitator air cleaner disposes a discharge electrode 71 and a counter electrode 72 in front of the filter, and applies a high voltage of 7000 V between them to cause corona discharge. It charges particles such as, and at this time,
By providing the filter with a conductor 5 having air permeability as a ground electrode, charged particles are electrically collected. 7 in the figure is a fan. In this case, the filter must be provided with the conductor 5 as described above, and at this time, it is necessary to ensure that the electrical connection to the conductor 5 is made reliably. For this purpose, we will introduce the back side of the dust removal filter material■,
In other words, an air permeable sheet-like conductor 5 is placed on the side of the deodorizing filter material 2, and both ends of the conductor 5 are placed over the outer surface of the frame 3 to cover the exposed portion. is used as a terminal portion 50, and when assembled into an air purifier, the terminal portions 50, 50 located on both sides come into contact with connection terminals provided in a filter installation portion of the air purifier. The reason why the terminal portions 50, 50 are provided on both sides is to eliminate directionality when the filter is assembled. The conductor 5 is formed by mixing conductive particles such as activated carbon or carbon into a nonwoven fabric made of polyester fibers. It may also be made of a nonwoven fabric made of nickel-coated fibers or metal fibers, although the latter is expensive. In the case shown in FIGS. 10 and 11, the frame 3 in which the terminal section 50 is disposed is eliminated, and the terminal section 50 also serves as the frame. In this case, the overall strength of the filter is maintained by adhesively fixing the cover 4 to the ridgeline of the peak of the filter material 1. As shown in FIGS. 12 and 13, the terminal portion 50 may be formed by cutting out a portion of the frame 3 and exposing a portion of the conductor 5 from this portion. Even in this case, directionality can be eliminated by providing the terminal portions 50 on both sides and positioning them in the center. Note that the ribs 10 do not have to extend in a direction perpendicular to the ridgeline of the peak of the filter part 1, and may intersect diagonally. Further, as shown in FIG. 14, the part of the dust removal filter 1 may have a cylindrical shape as a whole, and the ridge lines of the peaks may spread out radially. FIG. 15 shows a flowerpot-shaped air purifier equipped with the filter A shown in FIG. 14.

Because the ribs are provided, which is more severe due to the addition of melt material, the movement of the granular deodorizing filter material is prevented by the ribs. This eliminates problems, and since the ribs are made of hot melt material, the ribs can be easily provided regardless of the material of the dust removal filter material. According to the second feature, the presence of the terminal portion facilitates electrical connection, and it is possible to reliably use the conductor as a ground electrode when performing electrostatic precipitate collection.
