The best mode carried out an invention
Below humidification filter of the present invention and humidification filter layered product are specifically described.
As filter ground, can so resinous plate, film, the metal plate such as stainless steel or aluminium, film etc.Resinous plate, the film of preferred use non-foamed shape, to make it possible to form moisture film after hydrophilic treated, and then can suppress the attachment of incrustation scale.
The resin used in filter ground is without particular determination, include, for example out polystyrene resin, the aromatic species resins such as pet resin, acrylonitrile-styrene resin (AS resin), acrylonitrile-butadiene-styrene resin (ABS resin), the styrene resins such as Methyl Methacrylate-Styrene resin (MS resin), the butadiene type resins such as acrylonitrile-butadiene resin (AB resin), (methyl) acrylic resins such as poly-(methyl) methacrylate resin (PM (M) A resin), polyvinyl resin, the polyolefin resins such as acrylic resin, polycarbonate resin etc.
By making the lower thickness of filter ground, miniaturization and the lightweight of humidification filter and humidification filter layered product become possibility.Therefore, as filter ground, more preferably film is used.The thickness of filter ground without particular determination, but is preferably 50 ~ 1000 μm, is more preferably 50 ~ 500 μm, more preferably 200 ~ 500 μm.If the thickness of filter ground is lower than preferred scope, then there is the anxiety causing the distortion of filter ground or breakage.On the other hand, if the thickness of filter ground exceedes preferred scope, then in damping device, under unit volume, open ended humidification filters the minimizing of blade number, so there is the anxiety that cannot obtain enough humidifying performances.In addition, be also preferably in above-mentioned scope from the aspect of weight or cost.
As the means of jut, use the method for a part for crushed filter disc ground.As the method for this extruding, can list and form jut method by means of only extruding; A part for filter ground is cut, by extruding, relative to filter ground in method etc. that is vertical or incline direction bending.Compared with the method for carrying out extruding after a part of cutting filter, preferably form the method for jut by means of only extruding, this is due to can be cheap and form jut simply, and is difficult to the cause of the breakage causing filter ground without a side of cut.
The height of jut is preferably 0.5 ~ 3.0mm, is more preferably 1.0 ~ 2.0mm.If the height of jut is lower than preferred scope, then fully cannot guarantees the gap between humidification filter, make wind be difficult to pass through, have the anxiety that cannot export and add moisture.On the other hand, if the height of jut exceedes preferred scope, then in damping device, under unit volume, open ended humidification filters the minimizing of blade number, so there is the anxiety that cannot obtain enough humidifying performances.It should be noted that the quantity of jut, width indefinite can be determined arbitrarily according to the size of humidification filter.
By the humidification of humidification filter lamination with in filter layered product, when arranging the jut of adjacent humidification filter in the mode do not overlapped each other, the protuberance of jut does not enter the depressed part of adjacent humidification filter, adjacent humidification filter does not overlap each other, thus can not the gap passed through of inaccessible wind and stable output add moisture.For making the jut of the humidification filter adjoined not overlap each other, such as, the jut of adjacent humidification filter can be arranged at position different from each other.
As instantiation, the position of departing from (90/N) ° is in a circumferential direction being provided with the N kind of jut (wherein, N is the integer of more than 2) in the humidification filter layered product of humidification filter lamination successively, the jut of adjacent humidification filter is not overlapping, can be present in position different from each other.
Fig. 1 ~ 4 are provided with the schematic plan view of an example of the humidification filter wearing the hole 2 of axle and the involved in the present invention of multiple jut 3 on filter ground 10 for representing.Fig. 1 illustrates successively when N=2, depart from a circumferential direction (90/2) °=position of 45 ° is provided with the schematic plan view of 2 kinds of humidification filters of jut 3.When lamination 2 kinds of humidifications are with filter 1A and 1B successively, because humidification filter 1A and 1B jut 3 is separately not overlapping, can not the gap passed through of inaccessible wind and stable output add moisture.Fig. 2 is the schematic plan view of the humidification filter of the situation that N=3 is shown successively, and Fig. 3 is the schematic plan view of the humidification filter of the situation that N=6 is shown successively.
As other instantiation, as shown in Figure 4, jut 3 and the jut 3 of humidification filter 1D of humidification filter 1C are arranged respectively to different circle-shaped of radius, when adjacent, jut 3 each other also can be made not overlapping.
The hole of wearing axle or location mark are preferably set on humidification filter.If arrange the hole of wearing axle, then can not offsets formation pressure humidification filter.Fig. 5 and 6, for illustrate N=2 successively, to depart from (90/2) °=position of 45 ° is provided with the schematic plan view of 2 kinds of humidification filters of jut 3 in a circumferential direction.Wear the shape in the hole of axle without particular determination, but as (I) of Fig. 5 when the hole of wearing axle is positive round, when humidification rotates with filter layered product, humidification filter also rotates, and adjacent humidification filter exists overlapping possibility.Therefore, the shape of preferably wearing the hole of axle is not positive round.Such as, as (II) of Fig. 5 when the hole of wearing axle is octagon, when humidification rotates with filter layered product, humidification filter does not rotate, so adjacent humidification filter is not overlapping in rotary course, therefore preferably.But, as octagon during N=2, when the shape congruence in the hole of axle is worn in rotation (90/N) ° front and back in a circumferential direction, when carrying out lamination through axle on humidification filter, there is anisotropy when humidification filter rotates or passes thus the situation causing the jut of the humidification filter adjoined rarely overlapping.Therefore, as the humidification filter of Fig. 6 (I), preferably arrange location mark 11, or as Fig. 6 (II) ~ (IV), preferably making to rotate in a circumferential direction (90/N) ° front and back, to wear the shape in the hole of axle not congruent.Location mark arranges by printing and also arranges by adding indentation.When printing, the one side that only can be arranged at filter ground also can be arranged at two sides.
Humidification filter is as shown in Figure 1 the example being arranged jut 3 by extruding, and jut 3 is only formed at the one side of filter ground 10.Fig. 7 is the schematic cross-section of the jut 3 under the dotted line XY of Fig. 1.Fig. 8 is humidification filter 1E and 1F that jut is formed at the two sides of filter ground 10, and the jut of humidification filter 1E and 1F circumferentially departs from (90/2) °.Fig. 9 is the schematic cross-section under the dotted line ST of Fig. 8.At the opposing face of jut 3A (Fig. 8: solid line), extruding is provided with jut 3B (Fig. 8: dotted line).Like this, jut can be formed on the two sides of filter ground and also can only be formed at one side, but because the preparation of humidification filter is not time-consuming, and by making this jut can not make mistakes when lamination towards same direction ground lamination, thus more preferably jut only the side that one side is formed.
The shape of the jut formed by means of only extruding not particular determination is polygonal tapers such as prism-shaped, circular cone, pyrometric cone such as cylindric, triangular prism shape, bowl-shape etc.But, when the position of the jut of adjacent humidification filter is identical, when the Breadth Maximum of jut is below the width of the foot of jut, when lamination humidification filter, jut enters the depressed part of adjacent humidification filter, gap between humidification filter disappears, and makes wind be difficult to pass through, and adds moisture and reduces.Therefore, by the width making the Breadth Maximum of jut be greater than the foot of jut, even if the position of the jut between adjacent humidification filter is identical, jut is still made not overlap each other, the gap between humidification filter can be guaranteed, can guarantee stable to add moisture.
Cutting a part for filter ground, relative to filter ground in the method for vertical or incline direction bending, the shape of jut is not limited to arc-shaped, horn shape etc.But, such as when the both sides of cutting equilateral triangle, when base is in 90 ° relative to the bending of filter ground, if the position of the jut of adjacent humidification filter is identical, then jut enters the notch portion of adjacent filter ground, gap between filter ground disappears, and makes wind be difficult to pass through, and adds moisture and reduces.Therefore, jut is present in by the region with the width longer than broken line width, even if the position of the jut between adjacent humidification filter is identical, the jut of adjacent humidification filter also can not enter the notch portion of the jut being present in humidification filter, the gap between ground can be guaranteed, can provide stable and add moisture.
The shape of jut is as mentioned above without particular determination, but can be the shape of " length of the circumferencial direction of the length > jut of the radial direction of the humidification filter of jut, and the radius of the length < humidification filter of the radial direction of the humidification filter of jut ".Figure 10 represents schematic plan view filter ground 10 being provided with an example of the humidification filter wearing the hole 2 of axle and the involved in the present invention of multiple jut 3.Figure 11 is the enlarged drawing of the jut 3 of Figure 10, and symbol A is " length of the radial direction of the humidification filter of jut ", and symbol B is " length of the circumferencial direction of jut ".As " length of the circumferencial direction of the length > jut of the radial direction of the humidification filter of jut; and the jut of the radius of the length < humidification filter of the radial direction of the humidification filter of jut " concrete shape, the shape that fillet rectangle as shown in figure 11, rectangle, ellipse etc. are as shown in figure 12 elongated can be listed.
Figure 13 represents the humidification filter being provided with bowl-shape jut to impregnated in tank 20, and the schematic diagram of the flowing 23 of wind when direction of rotation 22 rotates, wind does not substantially collide with jut 3 and directly flows.On the other sidely be, as Figure 14, the humidification filter being provided with the jut 3 of elongated shape if make rotates, then because jut 3 makes the direction of the wind entered in humidification filter layered product change to downwards, so wind can be made by former wind to be difficult to the humidification filter layered product bottom flowed into, can increase and add moisture.
Figure 15 represents to impregnated in tank 20 by there is multiple humidification filter in order to the cave 7 by air, the schematic diagram of the flowing 23 of wind when direction of rotation 22 rotates.Owing to existing in order to the cave 7 by air, wind is made to pass this cave 7, thus can by between filter ground, the holdup time of wind increases, and can increase thus and add moisture.In order to can be arranged at the arbitrary place in filter ground 10 by the cave 7 of air, but due to for not making this cave 7 wetting and the side that is often preferably placed on the water surface 21, so be preferably disposed on the near middle of filter ground 10.
The shape of filter ground can list circle, polygon, star, waveform etc., if rotatable in time rotating in damping device, then shape is without particular determination, also can be irregular shape.But, the peripheral shape of filter ground is made concavo-convex, formed star or waveform (Figure 16) etc. time, the sectional area outside filter ground relative to compared with circle time increase, thus the area of water-wet increases, so obtain increasing the effect adding moisture.
Humidification filter preferably has hydrophilicity.Hydrophilicity is arranged in order to the object forming moisture film when damping device operates in the top layer of humidification filter, can provide stable humidifying performance.Hydrophilicity by use hydrophilic material as the material of filter ground method, make the discharge process such as the method for filter surface of bottom material roughening, plasma treatment or sided corona treatment, surfactant process, grafting process, the imparting such as method of hydrophilic layer be set.Wherein, the method for hydrophilic layer is preferably set from the point of excellent in te pins of durability.
