Below, with reference to accompanying drawing embodiments of the present invention are described.
Fig. 1 is the stereogram that the air cleaner that one embodiment of the present invention relates to is shown.
The air cleaner that air cleaner 10 possesses for filtered air inserts body 12 and is used for keeping air cleaner to insert the air filter frame 11 of body 12, consists of by the inside of air cleaner being inserted body 12 insertion air filter frames 11.Air filter frame 11 forms the quadrilateral frame shape by metal of timber, aluminium etc. etc.Air cleaner inserts body 12 and forms block filter material for filter 13 is converted into pleated.
Then, the structure for air cleaner insertion body 12 is described in more details.As shown in Figure 2, the folding line S that filter 13 extends along the width at filter 13 is converted into pleated (zigzag) with fixing fold height.Air cleaner inserts body 12 as shown in Figure 3, is converted into pleated by filter 13, forms the overlapping structure of a plurality of plane folding wall 14.And, in the following description, folding wall 14 overlapping directions are decided to be directions X.In addition, as shown in Figure 3, insert in the body 12 at air cleaner, air passes through to back side 13B side from the surperficial 13A of filter 13.That is to say, direction of ventilation is to downside from upside in Fig. 3.
Filter 13 filters airborne particles floating, inserts body 12 as long as can be configured as air cleaner, and any filtering material can.For example, as filter 13, can use the nonwoven of the filter paper that is made of glass fibre or TPO, polyesters, so long as can satisfy the filter of strainability, there is no particular limitation.
Be provided with the a plurality of the 1st and the 2nd protuberance 21,22 that processes shape by embossing at filter 13.Filter 13 is for example sent into along its length and is established on the outer peripheral face between irregular two rollers, carries out embossing processing between these two rollers.As shown in Figure 2, the 1st and the 2nd protuberance 21, the 22 one side sides from filter 13 (surperficial 13A or back side 13B side) depression, and protrude from another side side (back side 13B or surperficial 13A side).
The 1st protuberance 21 and the 2nd protuberance 22 are rolled on wall 14 along doubling direction (width of filter 13) alternative arrangement at each.The 1st interval of protuberance 21 on doubling direction is preferably 25-75mm, is more preferably about 50mm.The 2nd interval of protuberance 22 on doubling direction is preferably 25-75mm too, more preferably about 50mm.
Each is rolled over the 1st and the 2nd protuberance 21,22 that arranges on the wall 14 and is configured in same position with the 1st and the 2nd protuberance 21,22 that other roll over setting on walls 14 at doubling direction respectively.That is to say, in filter 13, as shown in Figure 2, the 1st protuberance 21 and the 2nd protuberance 22 that are arranged in row at the length direction of filter 13 are alternately arranged at doubling direction.
The 1st protuberance 21 alternately to protrude from the mode of surperficial 13A side and back side 13B side, is arranged a plurality of at doubling direction on each folding wall 14.Be arranged on (that is, arranging at the length direction of filter 13) a plurality of the 1st protuberances 21 of same position at doubling direction, protrude from the same face side (surperficial 13A side or back side 13B side) of filter 13.Therefore, a plurality of the 1st protuberances 21 that are arranged on same position at doubling direction as shown in Figure 3, and are when being converted into pleated, alternately outstanding at a direction and its rightabout along directions X.
By such structure, the 1st protuberance 21 is on a doubling wall 14,14 of adjacency, and outstanding in mode close to each other, its front end face 21A, 21A dock each other.Front end face 21A, the 21A that connects is fixing by the bonding agent (not shown) of smearing between them, thus, keeps between the folding wall 14,14 of adjacency separating.And the 1st protuberance 21 that protrudes from surperficial 13A side makes between folding wall 14,14 surperficial 13A, the 13A and keeps separating, and the 1st protuberance 21 that protrudes from back side 13B side makes between folding wall 14,14 back side 13B, the 13B and keeps separating.
Be configured in (that is, arranging at filter 13 length directions) a plurality of the 2nd protuberances 22 of same position at doubling direction, along the length direction of filter 13, alternately protrude from surperficial 13A side, back side 13B side.Therefore, be configured in the 2nd protuberance 22 of same position at doubling direction, outstanding in the same direction along directions X when being converted into pleated, insert in the body 12 at air cleaner, not mutually docking.
The 2nd protuberance 22 and the 1st protuberance 21 are same, on each folding wall 14, alternately to protrude from the mode of surperficial 13A side and back side 13B side, arrange a plurality of at doubling direction.Therefore, as shown in Figure 3, insert in the body 12 at air cleaner, at the 2nd protuberance 22 of giving prominence to along a direction of directions X with at the 2nd outstanding protuberance 22 of its rightabout, alternately arrange at doubling direction.
The the 1st and the 2nd protuberance 21,22 has the vertically extending shape with respect to folding line S at each folding wall 14.That is to say, protuberance 21,22 length directions at filter 13 extend, and extend slightly obliquely with respect to direction of ventilation in air cleaner insertion body 12.
The 1st protuberance 21 is connected in the 1st protuberance 21 of adjacency at folding line S place, arrange continuously a plurality of on the length direction of filter 13.That is to say, the length of the 1st protuberance 21 is identical with the width (that is, fold height) of folding wall 14.On the other hand, the 2nd protuberance 22 unshapeds are not connected at folding line S place with the 2nd protuberance 22 of adjacency near folding line S.That is to say, the 2nd protuberance 22 is arranged a plurality of on the length direction of filter 13 discontinuously, and the length of the 2nd protuberance 22 is the 1/2-2/3 of fold height.
The 1st protuberance 21 increases along its length direction projecting height.Here, the 1st protuberance 21 that protrudes from surperficial 13A side reduces gradually along the direction of ventilation height, simultaneously, protrudes from the 1st protuberance 21 of back side 13B side, increases gradually along the direction of ventilation height.Therefore, the distance between the folding wall 14 of adjacency, 14 surperficial 13A, the 13A shortens gradually along direction of ventilation, and the distance between back side 13B, the 13B is elongated gradually along direction of ventilation.
The 1st protuberance 21 is shown in Fig. 4,5, and the shape of its cross section is trapezoidal shape, and from the cardinal extremity forward end, its width diminishes gradually, and simultaneously, its front end face 21A forms the plane.And, the width of the 1st protuberance 21 cardinal extremities, roughly fixing on the length direction of protuberance 21.
On the other hand, the 2nd protuberance 22 is shown in Fig. 4-6, and the shape of its cross section and longitudinal section is trapezoidal shape, and from the cardinal extremity forward end, its width and length diminish gradually, and simultaneously, front end face 22A forms the plane parallel with rolling over wall 14.And, the width of the 2nd protuberance 22 (for example, the width of front end and cardinal extremity), roughly fixing on the length direction of protuberance 22.The width of the cardinal extremity of protuberance 22 is preferably 5-15mm, more preferably about 10mm.
In addition, the projecting height of the 2nd protuberance 22 is fixing in the direction perpendicular to folding line S.The projecting height of the 2nd protuberance 22 is the height between the height of the height of the highest part of the 1st protuberance 21 and lowermost portion, is preferably about 3-5mm specifically.In the situation that highly not enough 3mm, can not make air cleaner insert the filter area of body 12 enough large, if be higher than 5mm, then add the man-hour filter at embossing and breakage may occur.
Because the projecting height of the 2nd protuberance 22 is fixed, therefore near folding line S, as shown in Figure 5, when watching from the top, its front is configured to exceed folding line S.Here, be configured in a plurality of the 2nd protuberances 22 of same position at doubling direction, as mentioned above, outstanding to equidirectional on directions X, simultaneously, the width of the front of the 2nd protuberance 22 and Length Ratio base end side are little.Therefore, shown in Fig. 5,6, the part of front that exceeds the 2nd protuberance 22 of folding line S is contained in the inside (recess is inner) of base end side of the 2nd protuberance 22 of adjacency, and the 2nd protuberance 22 does not contact each other.And, as shown in Figure 6, in the present embodiment, be configured in a plurality of the 2nd protuberances 22 of same position at doubling direction, end on its length direction is configured in the inside of the other end of another protuberance 22, simultaneously, an end of another protuberance 22 is configured in the inside of the other end, forms the structure that so repeats.
As mentioned above, in the present embodiment, because as the part between the 1st protuberance 21 of separator, processing shape by embossing is the 2nd protuberance 22, therefore can increase the area that air cleaner inserts body 12.Because the 2nd protuberance 22 does not dock, contacts with other protuberance, therefore, by the area that the 2nd protuberance 22 increases, directly becomes the increase of effective filtration area, can effectively increase effective filtration area.And owing to being provided with the segment thickness attenuation of the 2nd protuberance 22, strainability is suitable, therefore also can suppress the pressure loss that air cleaner inserts body 12.
In the present embodiment, the 2nd protuberance 22 that is configured in same position at doubling direction is outstanding in same direction, and simultaneously, the part of each the 2nd protuberance 22 is disposed at the inside of another the 2nd protuberance 22.Therefore, can make the projecting height of each the 2nd protuberance 22 larger, be easy to increase effective filtration area.In addition, in the 2nd protuberance 22, because front end face 22A is the plane, and cross section and longitudinal section be trapezoidal, therefore can effectively increase the filter material area, improves simultaneously the rigidity of respectively rolling over wall 14.In addition, because the width of the 2nd protuberance 22 on its length direction and highly roughly fixing, so wind is easy to pass through along direction of ventilation.
In addition, in the present embodiment,, towards the 2nd ledge 22 of a direction of directions X and the 2nd ledge 22 of direction towards the opposite, at the doubling direction alternative arrangement.Therefore, can further improve the rigidity of folding wall 14, simultaneously, be easy to make wind to insert body 12 by air cleaner equably.
