【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、消臭等を行う空気清浄機のフィルタに関
するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for an air purifier that performs deodorization and the like.
従来、空気清浄機の消臭用のフィルタでは粒状活性炭
等の消臭剤を用いており、底部を格子状とした偏平な箱
状のフィルタケースに充填して網体で閉蓋している。BACKGROUND ART Conventionally, a deodorizing filter of an air purifier uses a deodorant such as granular activated carbon, and is filled in a flat box-shaped filter case having a lattice-like bottom portion and closed with a net.
消臭剤の移動を防止するため、特願昭58−158678号で
は、前記フィルタケースの底部に仕切突条を突設し、か
つ消臭剤をクッション材で押さえることが提案されてい
る。In order to prevent the movement of the deodorant, Japanese Patent Application No. 58-158678 proposes that a partition ridge is projected from the bottom of the filter case and the deodorant is held down by a cushion material.
しかし、仕切突条とクッション材による押さえ込みだ
けでは不充分であり、強い衝撃や輸送時の長時間の微振

では圧損が大きくなり、送風量が低下する。また、粉塵
が発生すると、外部に漏れた粉塵によりフィルタケース
の外面を汚し、見栄えが悪くなるという問題点が生じ
る。However, it is not enough to only hold down the ridges and the cushioning material, and the deodorant moves due to strong impact or long-term micro-vibration during transportation, creating a gap in the filter case or generating dust. May be. When the gap is formed as described above, the air flow is short-circuited and flows, and the air cleaning efficiency is reduced. In addition, the pressure loss is increased in a portion where the deodorant is biased and has a high density, and the amount of air blow is reduced. Further, when dust is generated, there is a problem that the external surface of the filter case is stained by the dust leaked to the outside and the appearance is deteriorated.

である。The present invention provides a flat box-shaped filter case having a gas-permeable bottom, a partition ridge protruding from the bottom to partition the inside into a plurality of sections, and the partition ridge located inside the section. A grid-like first filler movement preventer having a lower height than the first filler movement prevention body positioned inside a section defined by the first filler movement prevention body; A low grid-like second filler movement preventer, and a granular filler serving as a filter element filled in the filter case;
And a breathable lid that closes the filter case.

効果的に移動防止できる。According to the configuration of the present invention, the partition protrusion is protruded from the bottom of the filter case, and the first filler movement prevention member that is shorter than the partition protrusion and the second filler movement that is shorter than this. Since the prevention body is provided, the movement of the filler is reliably prevented by these, and the filler does not move due to vibration or impact and is not biased. For this reason, it is possible to prevent a gap from being formed in the packing material and prevent a short circuit flow from occurring, and prevent a pressure loss from increasing in a densely packed portion of the packing material, and maintain good air cleaning efficiency. In addition, there is no generation of dust due to the movement of the filler,
The filter case is prevented from being contaminated with dust. Further, the first filler movement preventing body is lower than the partitioning protrusion, and the second filling movement preventing body is lower than the first packing movement preventing body. In comparison, the filler can be filled to an appropriate density without hindering the filling of the filler, and the movement can be effectively prevented even if the particle size of the filler is large or small.

縦横に突設してある。The filter case 1 is a flat box having a bottom 2 meshed with vertical and horizontal lattices 2a. A partition ridge 3 for partitioning the interior into a plurality of sections is provided vertically and horizontally on the upper surface of the bottom 2. is there. The bottom part 2 of the filter case 1 is further provided with
Filler movement prevention body 5a consisting of a ridge with a lower protruding height than

効果がより一層良好に得られる。According to this configuration, in the partition section of the filter case 1 formed by the partitioning ridges 3, the packing movement prevention members 5 a and 5 b formed of ridges shorter than the partitioning ridges 3 are provided in a lattice shape. The object 6 is prevented from moving by the object movement preventing members 5a and 5b. In particular, this is effective when the diameter of the granular filler 6 is large or small, for example, when the diameter of the granular filler 6 is 3 mm or 2 mm. In other words, the small-diameter filler 6 is easy to move within each partitioning ridge 6, but the
The movement is blocked by a and 5b. In addition, even if the filler 6 is made of a material or a shape that is easy to move, the fixing is easily performed. Therefore, even by shock or long-term micro-vibration during transportation. The packing 6 is prevented from moving and being biased, and the packing 6
This prevents a short-circuit flow from occurring in the gap between them and prevents the pressure loss from increasing in a densely packed portion of the filling 6. Therefore, good air cleaning efficiency can be maintained. In addition, the filling 6
Is fixed, so that no dust is generated by the filler 6,
The filter case 1 is prevented from being contaminated with dust. Further, since the filler movement preventing members 5a and 5b are lower than the partitioning ridges 3, unlike the case where the tall partitioning ridges 3 are provided at a fine pitch, the filling of the filler 6 is not hindered. The object 6 can be filled to an appropriate density. The packing movement prevention bodies 5a and 5b
Although two types having different heights are provided, the effect of reliably preventing movement without lowering the packing density of the packing material 6 can be more favorably obtained.

Are composed of small projections protruding from each intersection of the lattice element 2a. As shown in FIG. 10, the packing movement prevention body 18 has a cross shape in a plan view and a triangular mountain shape in a front view, as shown by a hatched chain line. The height of the filler movement preventing member 18 is lower than the partitioning ridge 3 in FIG. Other configurations are the same as those of the first embodiment. As described above, even when a large number of small protrusion-shaped filler movement prevention members 18 are provided, the effect of preventing the movement of the filler material can be obtained as described above.

In particular, if the filling material 6 is small, if the filling material 6 is filled so as not to move to some extent, it becomes clogged, the pressure loss increases, and the suction amount cannot be increased. But,
When two types of fillers, large and small, are filled in this way, a gap is created between the large and small fillers, and pressure loss can be reduced.
In other words, it is possible to have an adjusting function for the pressure loss, it is possible to provide an appropriate suction amount, and it is possible to have a degree of freedom.

があっても効果的に移動防止できるという効果がある。A filter for an air purifier according to the present invention has a first protrusion that is protruded from a bottom portion of a filter case, and is lower than the first protrusion, and a second stopper that is shorter than this. Since the filler movement preventing member is provided, the movement of the filler is surely prevented by these, and the filler does not move due to vibration or impact and is not biased. For this reason, it is possible to prevent a gap from being formed in the packing material and prevent a short circuit flow from occurring, and prevent a pressure loss from increasing in a densely packed portion of the packing material, and maintain good air cleaning efficiency. Also, no dust is generated due to the movement of the filler, and the filter case is prevented from being contaminated with the dust. Further, the first filler movement preventing body is lower than the partitioning protrusion, and the second filling movement preventing body is lower than the first packing movement preventing body. In comparison with this, there is an effect that the filler can be filled to an appropriate density without disturbing the filling of the filler, and the movement can be effectively prevented even if the particle diameter of the filler is large or small.
