Description
本發明是在建築空調、產業空調等用途，關於一種為了捕集空氣中的微粒子所使用的空氣過濾器插入體，特別是關於一種濾材片被皺折狀地折彎而成塊狀的空氣過濾器插入體。The present invention relates to an air filter insert for use in collecting airborne particles, and more particularly to an air filter in which a filter sheet is bent into a block shape in a wrinkle-like manner. Insert the body.
以往，為了除去空氣中的塵埃或污染物質，濾材片被皺折地折彎的空氣過濾器插入體，係廣泛使用被收納在過濾器框內部的過濾器。一般來說，空氣過濾器插入體係設有保持折疊的濾材片間的間隔的隔片(separator)，確保通風。Conventionally, in order to remove dust or contaminants in the air, the filter sheet is folded and bent into an air filter insert, and a filter housed inside the filter frame is widely used. In general, the air filter insertion system is provided with a separator that maintains the spacing between the folded sheets of filter material to ensure ventilation.
例如，以浮凸(emboss)加工成形於濾材片的突出部，有做為隔片被使用者。因浮凸加工造成的突出部，在鄰接的濾材片間被設有者突出成彼此接近，其前端面彼此相對，在許多狀況，這些被接著劑接著而保持片間的間隔。For example, the protrusion formed on the filter sheet is processed by emboss, and the spacer is used by the user. The projections due to the embossing process are protruded from each other between the adjacent filter sheets, and the front end faces thereof face each other. In many cases, these adherends maintain the interval between the sheets.

此外，在濾材片被施加浮凸加工的狀況，是考慮因浮凸成形造成的延伸來設計。也就是說濾材片，即使被浮凸加工延伸而變薄，仍被設計成具有能確保所要求最低限度的濾過性能的厚度或密度(每單位面積的重量)。Further, in the case where the filter sheet is subjected to the embossing process, it is designed in consideration of the extension due to the embossing. That is to say, the filter sheet, even if it is thinned by the embossing process, is designed to have a thickness or density (weight per unit area) which ensures the required minimum filtration performance.
但是，由於如此設計，使以浮凸加工未延伸的部分過厚，所以會給予過濾器過剩的濾過性能，使壓力損失變大，有損害過濾器性能者。又，為了提昇過濾器性能，考量到濾材的有效濾過面積變大，但以簡單的方法使濾材的有效濾過面積變大的方法，以往並沒有被找到。However, since it is designed such that the portion which is not stretched by the embossing is too thick, the filter has an excessive filtration property, and the pressure loss is increased to impair the filter performance. Further, in order to improve the performance of the filter, it has been considered that the effective filtration area of the filter medium is increased, but the method of increasing the effective filtration area of the filter medium by a simple method has not been found in the past.
本發明有鑑於以上問題點，提供一種空氣過濾器插入體，以簡單的方法降低、抑制濾材的壓力損失，並使濾材的有效濾過面積提昇，具有良好的過濾器性能為目的。In view of the above problems, the present invention provides an air filter insert body, which reduces and suppresses the pressure loss of the filter material in a simple manner, and improves the effective filtration area of the filter material, and has the purpose of good filter performance.
關於本發明的空氣過濾器插入體具有濾材片被皺折狀地折彎而成塊狀的結構，用以濾過空氣，在空氣過濾器插入體，其特徵為：濾材片藉由被折彎而形成複數個折彎壁，在各折彎壁，以浮凸加工成形的第一突出部與第二突出部在摺痕方向並列，在鄰接的一對折彎壁設有的第一突出部，係突出成彼此接近，前端彼此相對，且第二突出部，係突出成彼此不相對。The air filter insert of the present invention has a structure in which a filter sheet is bent into a block shape, and is used to filter air in an air filter insert, wherein the filter sheet is bent by being bent. Forming a plurality of bending walls, wherein the first protruding portion and the second protruding portion formed by the embossing processing are juxtaposed in the direction of the fold in each of the bent walls, and the first protruding portion provided on the adjacent pair of bent walls is The protrusions are brought close to each other, the front ends are opposed to each other, and the second protrusions are protruded so as not to face each other.
第二突出部，較佳為彼此被配置在摺痕方向的相同位置，且在相同方向突出。在此狀況，各折彎壁所設有的各第二突出部，更佳為其一部分，被配置在鄰接該折彎壁的折彎壁所設有的第二突出部的內部。又，第二突出部係在一方向突出者與在其相反方向突出者，較佳為在摺痕方向交互地並列。又，第二突出部係突出成彼此不接觸為較佳。The second projections are preferably disposed at the same position in the direction of the folds and protrude in the same direction. In this case, each of the second projecting portions provided in each of the bent walls is preferably partially disposed inside the second projecting portion provided adjacent to the bent wall of the bent wall. Further, the second projecting portion is protruded in the opposite direction from the one in the opposite direction, preferably in the direction of the fold. Further, it is preferable that the second protruding portions protrude without coming into contact with each other.
第二突出部的突出高度，較佳為沿著其長方向為大致固定。又，第二突出部的前端面，較佳為平行於折彎壁的平面。第二突出部，較佳為在各折彎壁，具有對摺痕垂直延伸的形狀。又，第二突出部，其橫剖面形狀以及縱剖面形狀的一者，較佳為兩者是梯形。The protruding height of the second protruding portion is preferably substantially constant along the longitudinal direction thereof. Further, the front end surface of the second protruding portion is preferably parallel to the plane of the bent wall. The second projecting portion preferably has a shape in which the folds extend vertically in each of the bent walls. Further, it is preferable that the second protruding portion has a trapezoidal shape in one of a transverse cross-sectional shape and a longitudinal cross-sectional shape.
第一突出部，為例如與第二突出部同樣，在各折彎壁，對摺痕垂直延伸，但其突出高度較佳為沿著長方向增加。第一及第二突出部，為例如在摺痕方向交互地並列。The first projecting portion is, for example, similar to the second projecting portion, and the creases extend vertically in each of the bent walls, but the protruding height thereof preferably increases in the longitudinal direction. The first and second projections are alternately juxtaposed, for example, in the direction of the fold.
在本發明，藉由設有第二突出部，在空氣過濾器插入體，以簡單的方法可以降低壓力損失，並使濾材的有效濾過面積提昇。In the present invention, by providing the second projection, the air filter insert body can reduce the pressure loss in a simple manner and increase the effective filtration area of the filter medium.
參照以下圖式並說明本發明的實施形態。Embodiments of the present invention will be described with reference to the following drawings.
第一圖是表示關於本發明的一實施形態的空氣過濾器的斜視圖。The first figure is a perspective view showing an air filter according to an embodiment of the present invention.
空氣過濾器10具備：用以濾過空氣的空氣過濾器插入體12，與用以保持空氣過濾器插入體12的空氣過濾器框11，空氣過濾器插入體12係被插入空氣過濾器框11的內部而構成。空氣過濾器框11是以木材、鋁等金屬等形成為四角框狀。空氣過濾器插入體12是濾材片13被皺折狀地折彎而成塊狀的濾材。The air filter 10 includes an air filter insert 12 for filtering air, and an air filter frame 11 for holding the air filter insert 12, and the air filter insert 12 is inserted into the air filter frame 11. Internally constituted. The air filter frame 11 is formed in a square frame shape by a metal such as wood or aluminum. The air filter insert 12 is a filter material in which the filter material sheet 13 is bent into a block shape.
接下來，更詳細地說明關於空氣過濾器插入體12的結構。如第二圖所示，濾材片13是沿著在片13的寬方向延伸的摺痕S，以固定的折彎高度被皺折狀(曲折)地折彎。空氣過濾器插入體12，如第三圖所示，藉由濾材片被皺折狀地折彎，成為多個平面狀的折彎壁14被重疊的結構。又，在以下的說明中，將折彎壁14被重疊的方向做為X方向。又，如第三圖所示，在空氣過濾器插入體12，空氣從濾材片13的表面13A通過到背面13B側。也就是說，通風方向變成從在第三圖的上側到下側。Next, the structure of the air filter insert 12 will be explained in more detail. As shown in the second figure, the filter piece 13 is a crease S extending in the width direction of the sheet 13, and is bent at a fixed bending height by a wrinkle (zigzag). As shown in the third figure, the air filter insert 12 is bent in a corrugated shape by the filter sheet, and a plurality of planar bent walls 14 are overlapped. Moreover, in the following description, the direction in which the bending wall 14 is overlapped is referred to as the X direction. Further, as shown in the third figure, in the air filter insert 12, air passes from the surface 13A of the filter medium sheet 13 to the side of the back surface 13B. That is, the ventilation direction becomes from the upper side to the lower side of the third figure.
濾材片13只要是能濾過空氣中的懸浮粒子，成形為空氣過濾器插入體12者，則可以是任何過濾器材料。例如做為濾材片13，雖然使用由玻璃纖維組成的濾指或聚烯系、聚酯系的不織布，但若是滿足濾過性能的濾材片則沒有特別限定於這些。The filter material sheet 13 may be any filter material as long as it can filter suspended particles in the air and is formed into the air filter insert body 12. For example, as the filter medium sheet 13, a filter finger composed of glass fibers, a polyolefin-based nonwoven fabric or a polyester-based nonwoven fabric is used, but the filter medium sheet satisfying the filtration performance is not particularly limited thereto.
在濾材片13，設有以浮凸加工所成形的多個第一及第二突出部21、22。濾材片13為例如，在長方向被送到凹凸被設有在外周面的兩個滾筒間，在那些滾筒間進行浮凸加工。如第二圖所示，第一及第二突出部21、22，從片13的一面側(表面13A或背面13B側)內凹，並向他面側(背面13B或表面13A側)突出。The filter medium sheet 13 is provided with a plurality of first and second projecting portions 21 and 22 which are formed by embossing. The filter medium sheet 13 is, for example, sent to the unevenness and the outer peripheral surface between the two rollers in the longitudinal direction, and embossing is performed between those rollers. As shown in the second figure, the first and second projecting portions 21, 22 are recessed from one surface side (the surface 13A or the back surface 13B side) of the sheet 13, and protrude toward the other side (the back surface 13B or the surface 13A side).
第一突出部21與第二突出部22，在各折彎壁14，沿著摺痕方向(片13的寬方向)交互地並列。在第一突出部21的摺痕方向的間隔，較佳為25～75mm，約50mm為更佳。在第二突出部22的摺痕方向的間隔也一樣，較佳為25～75mm，約50mm為更佳。The first projecting portion 21 and the second projecting portion 22 are alternately juxtaposed in the fold direction (the width direction of the sheet 13) in each of the bent walls 14. The interval in the direction of the fold of the first projecting portion 21 is preferably 25 to 75 mm, more preferably about 50 mm. The interval in the direction of the fold of the second projecting portion 22 is also the same, preferably 25 to 75 mm, more preferably about 50 mm.
在各折彎壁14所設有的第一及第二突出部21、22，分別與其他的折彎壁14所設有的第一及第二突出部21、22，被配置在摺痕方向的相同位置。也就是說，在濾材片13，如第二圖所示，在片13的長方向並列成一列的第一突出部21與第二突出部22，在摺痕方向交互地並列。The first and second protruding portions 21 and 22 provided in each of the bent walls 14 and the first and second protruding portions 21 and 22 provided in the other bent walls 14 are disposed in the direction of the fold The same location. That is, in the filter medium sheet 13, as shown in the second figure, the first projecting portion 21 and the second projecting portion 22 which are juxtaposed in a row in the longitudinal direction of the sheet 13 are alternately juxtaposed in the direction of the fold.
第一突出部21，在各折彎壁14，在摺痕方向複數個並列成在表面13A側及背面13B側交互地突出。在摺痕方向的相同位置所設有的(即在片13的長方向並列)複數個第一突出部21，係在濾材片13的同一面側(表面13A側或背面13B側)突出。因此，在摺痕方向相同位置所設有的複數個第一突出部21，如第三圖所示被皺折狀地折彎時，在沿著X方向的一方向與其反方向交互地突出。The first projecting portions 21 are alternately arranged in the fold direction in the fold direction 14 so as to alternately protrude on the side of the front surface 13A and the side of the back surface 13B. A plurality of first projecting portions 21 provided at the same position in the fold direction (that is, juxtaposed in the longitudinal direction of the sheet 13) protrude from the same surface side (the surface 13A side or the back surface 13B side) of the filter medium sheet 13. Therefore, when the plurality of first projecting portions 21 provided at the same position in the fold direction are wrinkled as shown in the third figure, they are alternately protruded in the opposite direction in the X direction.
以如此結構，第一突出部21在鄰接的一對折彎壁14、14，突出成彼此接近，其前端面21A、21A彼此相對。相對的前端面21A、21A，被塗佈於該些間的接著劑(圖未顯示)所固定，藉此，鄰接的折彎壁14、14間保持分離。又，在表面13A側突出的第一突出部21，使折彎壁14、14的表面13A、13A間保持分離，在背面13B側突出的第一突出部21，使折彎壁14、14的背面13B、13B間保持分離。With such a configuration, the first projecting portion 21 protrudes in proximity to each other in the adjacent pair of bent walls 14, 14, and the front end faces 21A, 21A face each other. The opposing front end faces 21A and 21A are fixed by an adhesive (not shown) applied between the front end faces 21A and 21A, whereby the adjacent bent walls 14 and 14 are kept separated. Further, the first projecting portion 21 projecting on the side of the front surface 13A keeps the surfaces 13A and 13A of the bent walls 14 and 14 separated, and the first projecting portion 21 projecting on the side of the back surface 13B causes the bent walls 14 and 14 to be bent. The back faces 13B and 13B are kept separated.
在摺痕方向的相同位置所配置的(即在片13的長方向並列)複數個第二突出部22，沿著片13的長方向，在表面13A側、背面13B側交互地突出。因此，在摺痕方向的相同位置所配置的第二突出部22，被皺折狀地折彎時，變成在沿著X方向的相同方向突出，在空氣過濾器插入體12彼此不相對。A plurality of second projecting portions 22 disposed at the same position in the fold direction (that is, juxtaposed in the longitudinal direction of the sheet 13) alternately protrude on the surface 13A side and the back surface 13B side along the longitudinal direction of the sheet 13. Therefore, when the second projecting portions 22 disposed at the same position in the fold direction are bent in a wrinkle shape, they protrude in the same direction along the X direction, and the air filter inserts 12 do not face each other.
第二突出部22，與第一突出部21一樣，在各折彎壁14，在摺痕方向複數個並列成在表面13A側以及背面13B側交互地突出。因此，如第三圖所示，在空氣過濾器插入體12，第二突出部22是在沿著X方向的一方向突出者，與在其相反方向突出者，在摺痕方向交互地並列。The second projecting portion 22, like the first projecting portion 21, is alternately arranged in the fold direction in the fold direction 14 so as to alternately protrude on the side of the front surface 13A and the side of the back surface 13B. Therefore, as shown in the third figure, in the air filter insert body 12, the second projecting portion 22 is protruded in one direction along the X direction, and is juxtaposed in the direction of the fold in the direction opposite to the fold in the opposite direction.
第一及第二突出部21、22，在各折彎壁14具有對摺痕S垂直延伸的形狀。也就是說，突出部21、22在濾材片13的長方向延伸，且在空氣過濾器插入體12對通風方向些微傾斜而延伸。The first and second protruding portions 21 and 22 have a shape in which each of the bent walls 14 extends perpendicularly to the crease S. That is, the protruding portions 21, 22 extend in the longitudinal direction of the filter material sheet 13, and extend in the air filter inserting body 12 with a slight inclination to the ventilation direction.
第一突出部21，在摺痕S連接於鄰接的第一突出部21，在片13的長方向連續而複數個並列。也就是說，第一突出部21的長度，變成與折彎壁14的寬度(即折彎高度)相同。另一方面，第二突出部22未成形於摺痕S附近，在摺痕S未連接於鄰接的第二突出部22。也就是說，第二突出部22，在片13的長方向，不連續地複數個並列，第二突出部22的長度成為折彎高度的1/2～2/3。The first protruding portion 21 is connected to the adjacent first protruding portion 21 at the crease S, and is continuous in the longitudinal direction of the sheet 13 and plural in parallel. That is, the length of the first protruding portion 21 becomes the same as the width of the bent wall 14 (i.e., the bending height). On the other hand, the second projecting portion 22 is not formed in the vicinity of the crease S, and the crease S is not connected to the adjacent second projecting portion 22. That is, the second projecting portion 22 is juxtaposed in a plurality of discontinuous directions in the longitudinal direction of the sheet 13, and the length of the second projecting portion 22 is 1/2 to 2/3 of the bending height.
第一突出部21，沿著其長方向突出高度會增加。在此，在表面13A側突出的第一突出部21，沿著通風方向高度逐漸減少，並且在背面13B側突出的第一突出部21，沿著通風方向高度逐漸增加。因此，鄰接的折彎壁14、14的表面13A、13A間的距離，沿著通風方向逐漸變短，並且背面13B、13B間的距離，沿著通風方向逐漸變長。The first protruding portion 21 has a height that protrudes along the long direction thereof. Here, the first protrusion 21 protruding on the side of the surface 13A gradually decreases in height along the ventilation direction, and the first protrusion 21 protruding on the side of the back surface 13B gradually increases in height along the ventilation direction. Therefore, the distance between the surfaces 13A, 13A of the adjacent bent walls 14, 14 gradually becomes shorter along the ventilation direction, and the distance between the back faces 13B, 13B gradually becomes longer along the ventilation direction.
第一突出部21，如第四、五圖所示，其橫剖面的形狀呈現梯形形狀，從基端向著前端，其寬度逐漸變小，並且其前端面21A成為平面。又，在第一突出部21的基端的寬度，在突出部21的長方向為大致固定。As shown in the fourth and fifth figures, the first projecting portion 21 has a trapezoidal shape in a cross-sectional shape, and its width gradually decreases from the base end toward the front end, and the front end surface 21A thereof becomes a flat surface. Further, the width of the base end of the first protruding portion 21 is substantially constant in the longitudinal direction of the protruding portion 21.
另一方面，第二突出部22，如第四～六圖所示，其橫剖面以及縱剖面的形狀呈現梯形形狀，從基端向著前端，其寬度以及長度逐漸變小，並且前端面22A成為平行於折彎壁14的平面。又，第二突出部22的寬度(例如前端以及基端的寬度)，在突出部22的長方向為大致固定。在突出部22的基端的寬度，較佳為5～15mm，更佳為約10mm。On the other hand, as shown in the fourth to sixth figures, the second projecting portion 22 has a trapezoidal shape in cross section and a longitudinal cross section, and its width and length gradually decrease from the base end toward the front end, and the front end surface 22A becomes Parallel to the plane of the curved wall 14. Further, the width of the second protruding portion 22 (for example, the width of the front end and the base end) is substantially constant in the longitudinal direction of the protruding portion 22. The width of the base end of the projection 22 is preferably 5 to 15 mm, more preferably about 10 mm.
再者，第二突出部22的突出高度，在垂直於摺痕S方向為固定。第二突出部22的突出高度，是第一突出部21的最高部分的高度，與最低部分的高度間的高度，具體來說是約3～5mm為較佳。因為是在高度未滿3mm的狀況，空氣過濾器插入體12的濾過面積不夠大，超過5mm的高度則浮凸加工時濾材片有破損之虞。Further, the protruding height of the second protruding portion 22 is fixed perpendicular to the direction of the crease S. The protruding height of the second protruding portion 22 is the height of the highest portion of the first protruding portion 21, and the height between the height of the lowest portion, specifically, about 3 to 5 mm is preferable. Because the height is less than 3 mm, the filtration area of the air filter insert 12 is not large enough, and if the height exceeds 5 mm, the filter sheet is damaged during the embossing.
由於第二突出部22其突出高度為固定，所以在摺痕S附近，其前端側，如第五圖所示從上方來看，變成超過摺痕S被配置。在此，在摺痕方向的相同位置所配置的複數個第二突出部22，如上述，在X方向的相同方向突出，並且第二突出部22的前端側，其寬度以及長度比基端側更小。因此，如第五、六圖所示，超過摺痕S的第二突出部22的前端側，其一部分收納於鄰接的第二突出部22的基端側的內部(凹部內部)，第二突出部22彼此沒有接觸。又，如第六圖所示，在本實施形態，在摺痕方向的相同位置所配置的複數個第二突出部22，在其長方向的一端被配置於其他突出部22的他端的內部，並且其他的突出部22的一端被配置在他端的內部，成為重複此的結構。Since the protruding height of the second protruding portion 22 is fixed, the front end side of the second protruding portion 22 is disposed beyond the crease S as viewed from above as shown in the fifth figure. Here, the plurality of second protrusions 22 disposed at the same position in the fold direction protrude as in the same direction in the X direction as described above, and the front end side of the second protrusion 22 has a width and a length larger than the base end side. smaller. Therefore, as shown in the fifth and sixth figures, a part of the distal end side of the second protruding portion 22 that exceeds the crease S is housed inside the proximal end side of the adjacent second protruding portion 22 (inside the concave portion), and the second projection The portions 22 are not in contact with each other. Further, as shown in the sixth embodiment, in the present embodiment, the plurality of second projecting portions 22 disposed at the same position in the fold direction are disposed at the other end of the other projecting portion 22 at one end in the longitudinal direction. Further, one end of the other protruding portion 22 is disposed inside the other end, and this structure is repeated.
如上述，在本實施形態，由於為隔片的第一突出部21之間的部分，被浮凸加工成形為第二突出部22，所以可使空氣過濾器插入體12的面積增加。因為第二突出部22，並未與其他突出部相對、接觸，所以以第二突出部22增加的面積，仍是有效濾過面積的增加量，可以使有效濾過面積有效率地提昇。然後，因為第二突出部22被設有的部分，係厚度變薄，濾過性能為適當者，所以可以抑制空氣過濾器插入體12的壓力損失。As described above, in the present embodiment, since the portion between the first protruding portions 21 of the spacer is embossed into the second protruding portion 22, the area of the air filter insert 12 can be increased. Since the second protruding portion 22 does not face and contact with the other protruding portions, the increased area of the second protruding portion 22 is still an increase amount of the effective filtering area, and the effective filtering area can be efficiently raised. Then, since the portion where the second projecting portion 22 is provided is thinned and the filtration performance is appropriate, the pressure loss of the air filter insert 12 can be suppressed.
在本實施形態，在摺痕方向的相同位置所配置的第二突出部22，在相同方向突出，並且各第二突出部22的一部分，被配置在其他的第二突出部22的內部。因此，各第二突出部22的突出高度可變得相對大，變得容易使有效濾過面積增加。又，第二突出部22在前端面22A為平面，且橫剖面與縱剖面為梯形，所以使濾材面積有效率地提昇，並可以使各折彎壁14的剛性也提昇。再者，第二突出部22，在其長方向的寬度與高度為大致固定，所以在通風方向風變得容易通過。In the present embodiment, the second protruding portions 22 disposed at the same position in the fold direction protrude in the same direction, and a part of each of the second protruding portions 22 is disposed inside the other second protruding portions 22. Therefore, the protruding height of each of the second protruding portions 22 can become relatively large, and it becomes easy to increase the effective filtering area. Further, since the second projecting portion 22 has a flat surface on the front end surface 22A and a trapezoidal cross section and a longitudinal cross section, the filter material area can be efficiently raised, and the rigidity of each of the bent walls 14 can be improved. Further, since the width and height of the second projecting portion 22 in the longitudinal direction are substantially constant, the wind easily passes through in the ventilation direction.
又，在本實施形態，第二突出部22，是向著X方向的一方向者，與向著相反方向者，在摺痕方向交互地並列。因此，可以使折彎壁14的剛性更加提昇，並且在空氣過濾器插入體12均勻地讓風變得容易通過。Further, in the present embodiment, the second projecting portion 22 is oriented in one direction in the X direction, and is alternately arranged in the direction of the fold in the opposite direction. Therefore, the rigidity of the bent wall 14 can be further increased, and the air filter insert body 12 uniformly allows the wind to easily pass.
