The combination that constitutes the sheet filtering material of above-described middle high-performance filter, accurate HEPA filter, HEPA filter, ulpa filter only is an example, is not limited to this situation, also can not change purport of the present invention even carry out various changes.
The effect of technique scheme is as described below.Filter selected is to change and the variation of surrounding environment determines according to meteorology, here narrates at the situation of middle high-performance filter.
At first, in this in high-performance filter, if send into contaminated air from filter housing front, then this contaminated air is by the gap between a plurality of filtering materials that formed by division board or wire adhesive, at first utilize the bigger sheet filtering material of dust-holding capacity of upstream side, will remove more than or equal to the dust-filtering control of dust of micro mist dirt size.Thus, only with micro mist dirt trap filter, thus, cleaned air passes is discharged to filter housing back side in the fine and close more sheet filtering material of waterproof processing for entering after the contaminated air of micro mist dirt by implementing.Thus, because the big sheet filtering material of above-mentioned dust-holding capacity captures bigger dust, highdensity sheet filtering material only captures micro mist dirt, so dust catching capacity as a whole increases, and can realize the arresting efficiency of highdensity sheet filtering material raising, with and life-time dilatation, can use for a long time.
Particularly, be vaporific or have under the situation of sea salt particle of hygroscopy at dust, probably attached on the upstream side sheet filtering material and soak into and lateral plate shape filtering material diffusion downstream, but owing to compare with upstream side sheet filtering material, downstream sheet filtering material has stronger waterproof effect, thus not downstream lateral plate shape filtering material fly out.
In addition, because two different sheet filtering materials are overlapped, compare with existing a slice sheet filtering material, filtering material intensity increases, thus quite big even the pressure loss becomes, can not use not damagedly yet.
The effect of invention
As mentioned above, filter for air condition of the present invention can obtain effect as described below.
(1) on the basis owing to corresponding each filtering material of selecting out the formation filtering material with the variation of surrounding environment, and the upstream side that makes airflow direction becomes the bigger sheet filtering material of dust-holding capacity, so can keep dust morely, downstream sheet filtering material is arranged to compare with upstream side sheet filtering material, the fine and close more sheet filtering material by implementing waterproof processing, long-life filter for air condition so lower pressure loss can be provided.
(2) owing to utilizing the bigger particle of the rough removal of upstream side sheet filtering material, so can alleviate the burden of downstream sheet filtering material significantly.
(3) since the fibre structure from the upstream side of airflow direction to the downstream be changed to 2 sections best density gradients, so satisfy required capture performance, and, suppress the extreme increase of the pressure loss, life-saving with the amount of collected equalization of filtering material.
(4) life-span owing to filtering material prolongs, so can reduce the maintenance cost of air cleaning unit.
(5) owing to can suppress the extreme increase of the pressure loss, so can realize the saving of the running cost of drive unit such as fan.
(6) because filtering material forms duplex, so when assemble, breakage can not take place, fold problems such as bad to the processing of filtering material fold and as filter.

The specific embodiment
Below, based on accompanying drawing 1 to 4, filter for air condition of the present invention is described.
In the drawings, the 1st, the housing of filter for air condition forms the open box shape of front-back, and in this housing 1, the filtering material 2 of duplex is compact on the whole as shown in the figure, and installs circuitously with Z word shape for filter area is increased.Promptly, shown in Fig. 2 amplifies, between this kink 3,3....... with the filtering material 2 of Z word shape bending, tabular division board 4, the 4...... of configuration waveform, these division boards 4,4...... with the direction of the folding line quadrature of kink 3,3...... on form wave, perhaps, similarly as Fig. 3 with and part amplify shown in Figure 4, in housing 1, filtering material 2 is installed circuitously with Z word shape, sandwich binding resin 5, the 5...... of wire or rope form at its outer surface, form a plurality of ventilations road 6,6.......
The filtering material 2 of above-mentioned dual structure, become upstream side sheet filtering material 7 and downstream sheet filtering material 8 are overlapped the density gradient type structure that forms, this upstream side sheet filtering material 7 is made by glass fibre, dust-holding capacity is bigger, this downstream sheet filtering material 8 is similarly made by glass fibre, and implements waterproof processing, fine and close more.
And, different two sheet filtering materials 7,8 of above-mentioned coincidence are respectively the paper shape, density difference each other, be configured in the upstream side sheet filtering material 7 of front face side with respect to air-polluting inflow direction, it is the lower sheet filtering material of density that captures big dust, being configured in the downstream sheet filtering material 8 of its back side, is the higher sheet filtering material of density that captures micro mist dirt.
Action to said structure describes below, if contaminated air is sent into from the front face side of housing 1, then this contaminated air enters into kink 3, open a plurality of ventilations road 6, the 6...... of the front face side between the 3...... at filtering material, and at first utilizes the bigger upstream side sheet filtering material 7 of dust-holding capacity to capture more than or equal to the bigger dust-filtering of micro mist dirt and to remove.Thus, the contaminated air that only comprises micro mist dirt enters into fine and close downstream sheet filtering material 8 afterwards, and with micro mist dirt trap filter, thus, the air that is cleaned is discharged to the back of filter side, supplies with as clean air.
Therefore, (also comprise dust owing in the bigger upstream side sheet filtering material 7 of above-mentioned dust-holding capacity, capture bigger dust, below identical), in the downstream of densification sheet filtering material 8, only capture micro mist dirt, so the capture capacity of dust is increased, and realize the raising of the arresting efficiency of downstream sheet filtering material 8, with and life-time dilatation, can use for a long time.
In addition, owing to being overlapped, two different sheet filtering materials 7,8 form density gradient type structure, thus compare with existing a slice filtering material, because filtering material intensity is big, even it is the pressure loss is quite big in the use of filter, also can not can damaged.
Below, the manufacture method of filter for air condition is described.
