Detailed description of the invention
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.
Air cleaner 10 possesses for the Air filter insert 12 of filtered air with for keeping the air filter frame 11 of Air filter insert 12, forms by Air filter insert 12 is inserted the inside of air filter frame 11.Air filter frame 11 forms quadrilateral frame rack-like by the metal etc. of timber, aluminium etc.Air filter insert 12 is for filter 13 is converted into pleated and form block filter material.
Then, the structure for Air filter insert 12 is described in more details.As shown in Figure 2, the folding line S that filter 13 extends on the width at filter 13, is converted into pleated (zigzag) with fixing fold height.Air filter insert 12 as shown in Figure 3, is converted into pleated by filter 13, forms the structure of multiple plane folding wall 14 overlap.Further, in the following description, the direction of folding wall 14 overlap is decided to be X-direction.In addition, as shown in Figure 3, in Air filter insert 12, air rearwardly passes through 13B side from the surperficial 13A of filter 13.That is, direction of ventilation is from the upper side to the lower side in figure 3.
Particles floating in air filters by filter 13, as long as can be configured as Air filter insert 12, any filtering material can.Such as, as filter 13, can use the non-woven fabrics of the filter paper that is made up of glass fibre or TPO, polyesters, as long as can meet the filter of strainability, there is no particular limitation.
Filter 13 is provided with the multiple 1st and the 2nd protuberance 21,22 that embossing processes shape.Filter 13 is such as sent into along its length and outer peripheral face is established between irregular two rollers, between these two rollers, carry out embossing processing.As shown in Figure 2, the 1st and the 2nd protuberance 21,22 caves in from the one side side (surperficial 13A or 13B side, the back side) of filter 13, and protrudes from another side side (back side 13B or surperficial 13A side).
1st protuberance 21 and the 2nd protuberance 22 are alternately arranged along doubling direction (width of filter 13) on each folding wall 14.1st interval of protuberance 21 on doubling direction, is preferably 25-75mm, is more preferably about 50mm.2nd interval of protuberance 22 on doubling direction is preferably 25-75mm too, is more preferably about 50mm.
The the 1st and the 2nd protuberance 21,22 that each folding wall 14 is arranged is configured in same position with the 1st and the 2nd protuberance 21,22 of setting on other folding walls 14 respectively on doubling direction.That is, in filter 13, as shown in Figure 2, the 1st protuberance 21 and the 2nd protuberance 22 that the length direction of filter 13 are arranged in row are alternately arranged on doubling direction.
1st protuberance 21 alternately to protrude from the mode of surperficial 13A side and 13B side, the back side, doubling direction arranges multiple on each folding wall 14.Doubling direction is arranged on (that is, the length direction of filter 13 arranging) multiple 1st protuberance 21 of same position, protrudes from the same face side (surperficial 13A side or 13B side, the back side) of filter 13.Therefore, doubling direction is arranged on multiple 1st protuberances 21 of same position as shown in Figure 3, when being converted into pleated, alternately outstanding on a direction in X direction and its rightabout.
By such structure, the 1st protuberance 21 is on an adjacent doubling wall 14,14, and give prominence in mode close to each other, its front end face 21A, 21A dock each other.Front end face 21A, 21A of connecting are fixed by the bonding agent (not shown) smeared between which, thus, keep being separated between adjacent folding wall 14,14.Further, the 1st protuberance 21 protruding from surperficial 13A side makes surperficial the maintenance between 13A, 13A of folding wall 14,14 be separated, and the 1st protuberance 21 protruding from 13B side, the back side makes the maintenance between the back side 13B, 13B of folding wall 14,14 be separated.
Doubling direction is configured in (that is, filter 13 length direction arranging) multiple 2nd protuberance 22 of same position, along the length direction of filter 13, alternately protrudes from surperficial 13A side, 13B side, the back side.Therefore, doubling direction is configured in the 2nd protuberance 22 of same position, when being converted into pleated, projecting upwards same side in X direction, in Air filter insert 12, mutually not docking.
2nd protuberance 22 is same with the 1st protuberance 21, on each folding wall 14, alternately to protrude from the mode of surperficial 13A side and 13B side, the back side, doubling direction arranges multiple.Therefore, as shown in Figure 3, in Air filter insert 12, the 2nd protuberance 22 projected upwards a side in X direction and the 2nd protuberance 22 outstanding on its rightabout, doubling direction is alternately arranged.
The protuberance 21,22 of the 1st and the 2nd, each folding wall 14 has relative to the vertically extending shape of folding line S.That is, protuberance 21,22 extends on the length direction of filter 13, and extends slightly obliquely relative to direction of ventilation in Air filter insert 12.
1st protuberance 21, is connected to the 1st adjacent protuberance 21 at folding line S place, the length direction of filter 13 arranges continuously multiple.That is, 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 unshaped, near folding line S, is not connected at folding line S place with the 2nd adjacent protuberance 22.That is, the 2nd protuberance 22 arranges multiple discontinuously on the length direction of filter 13, and the length of the 2nd protuberance 22 is the 1/2-2/3 of fold height.
1st protuberance 21 along its length projecting height increases.Here, the 1st protuberance 21 protruding from surperficial 13A side reduces gradually along direction of ventilation height, meanwhile, protrudes from the 1st protuberance 21 of 13B side, the back side, increases gradually along direction of ventilation height.Therefore, the surperficial distance between 13A, 13A of adjacent folding wall 14,14 shortens gradually along direction of ventilation, and distance between the back side 13B, 13B is elongated gradually along direction of ventilation.
As shown in Figure 4,5, the shape of its cross section is trapezoidal shape to 1st protuberance 21, and from cardinal extremity forward end, its width diminishes gradually, and meanwhile, its front end face 21A forms plane.Further, the width of the 1st protuberance 21 cardinal extremity, roughly fixing on the length direction of protuberance 21.
On the other hand, as Figure 4-Figure 6, the shape of its cross section and longitudinal section is trapezoidal shape to the 2nd protuberance 22, and from cardinal extremity forward end, its width and length diminish gradually, and meanwhile, front end face 22A forms the plane parallel with folding wall 14.Further, the width (such as, the width of front end and cardinal extremity) of the 2nd protuberance 22, roughly fixing on the length direction of protuberance 22.The width of the cardinal extremity of protuberance 22 is preferably 5-15mm, is more preferably about 10mm.
In addition, the projecting height of the 2nd protuberance 22 is fixing on the direction perpendicular to folding line S.The projecting height of the 2nd protuberance 22, is the height between the height that divides of the highest portion of the 1st protuberance 21 and the height of lowermost portion, is preferably about 3-5mm specifically.When highly less than 3mm, the filter area that can not make Air filter insert 12 is enough large, if higher than 5mm, then adds man-hour filter at embossing and may occur breakage.
Because the projecting height of the 2nd protuberance 22 is fixed, therefore near folding line S, as shown in Figure 5, when viewed from above, its front is configured to exceed folding line S.Here, doubling direction is configured in multiple 2nd protuberances 22 of same position, as mentioned above, outstanding to equidirectional in the X direction, meanwhile, width and the length of the front of the 2nd protuberance 22 are less than base end side.Therefore, as shown in Figure 5,6, the part exceeding the front of the 2nd protuberance 22 of folding line S is contained in the inside of the base end side of the 2nd adjacent protuberance 22 (recess is inner), and the 2nd protuberance 22 does not contact each other.And, as shown in Figure 6, in the present embodiment, doubling direction is configured in multiple 2nd protuberances 22 of same position, one end on its length direction is configured in the inside of the other end of another protuberance 22, meanwhile, one end of another protuberance 22 is configured in the inside of the other end, forms the structure so repeated.
As mentioned above, in the present embodiment, due to the part between the 1st protuberance 21 as separator, processing shape by embossing is the 2nd protuberance 22, therefore, it is possible to increase the area of Air filter insert 12.Because the 2nd protuberance 22 does not dock with other protuberance, contacts, therefore, the area increased by the 2nd protuberance 22, is directly become the increase of effective filtration area, effectively can increase effective filtration area.And because the segment thickness being provided with the 2nd protuberance 22 is thinning, strainability is suitable, therefore also can suppress the pressure loss of Air filter insert 12.
In present embodiment, the 2nd protuberance 22 that doubling direction is configured in same position is given prominence in the same direction, and meanwhile, a part for each the 2nd protuberance 22 is configured at the inside of another the 2nd protuberance 22.Therefore, it is possible to make the projecting height of each the 2nd protuberance 22 comparatively large, be easy to increase effective filtration area.In addition, in the 2nd protuberance 22, because front end face 22A is plane, and cross section and longitudinal section are trapezoidal, increase filter material area, improve the rigidity of each folding wall 14 simultaneously therefore, it is possible to effective.In addition, due to the 2nd protuberance 22 width in their length direction and highly roughly fixing, therefore wind is easy to pass through along direction of ventilation.
In addition, in present embodiment, towards the 2nd ledge 22 in a direction of X-direction and the 2nd ledge 22 in direction towards the opposite, be alternately arranged at doubling direction.Therefore, it is possible to improve the rigidity of folding wall 14 further, meanwhile, be easy to make wind uniformly across Air filter insert 12.
