(detailed description)
For indoor air-changing, it is primarily present three kinds of systems.The first be by mechanical (electric fan) force to carry out air inlet and The first air exchange system of exhaust.Be for second exhaust side be natural ventilation, air inlet side taken a breath by mechanical forced Two kinds of air exchange systems.It is this to be chiefly used in clean room etc., hardly it is used for house.The third be by mechanically ventilated forced exhaust, In the third air exchange system of natural inflow mouth (indoor air-changing adjuster) air inlet.
It is different from the mechanically ventilated formula air inlet of the first air exchange system or second of air exchange system, the third ventilation system The air inlet in a manner of natural inflow of the air inlet of system, therefore, it is necessary to attention, are set to the filtering of the changing regulator of air inlet The usual pressure loss of device is smaller.The reason is that in the third air exchange system, if the pressure loss of changing regulator compared with Greatly, then need the motor ability of electrical exhaust fan larger, accordingly, there exist the risks of indoor pressure-reducing.In addition, the first ventilation system The air inlet air quantity of system and second of air exchange system is fixed, in this regard, the air quantity of the air inlet of the third air exchange system can occur Larger variation, this point of the air inlet of the changing regulator of the third air exchange system also with the first and take a breath for second The air inlet of system is different.
Present inventors discovered unexpectedly that nanometer can be used in the changing regulator of the third air exchange system Filter filtration material.For nanofilter filter material, through observation shows that be non-woven fabrics, furthermore it is possible to feel that surface density is higher, Therefore, it is believed in the art that, in terms of the pressure loss, is not used to the changing regulator of the third air exchange system.Example Such as, in recent years, in the room usually using buildings such as the apartments of the third air exchange system, due to the seal in room itself It is higher, therefore, if the pressure loss performance of changing regulator is poor, larger pressure difference can be generated in the indoor and outdoor in room, Cause sometimes the strength with children can not open door.As described above, the changing regulator of the third air exchange system is especially in the presence of The problem of pressure loss.In practice, electrostatic filter can be only used in the changing regulator of the third air exchange system, at most The microstrainer for the fiber for being 1 μm or more with fibre diameter can be used.
But the inventors found that by the way that nanofilter filter material is used for changing regulator, the pressure loss is simultaneously It is poor unlike existing changing regulator, further, it is possible to the tremendous arresting efficiency for promoting finely ground particles.
In the present invention, the fibre diameter for the nanofilter of the changing regulator of natural inflow mouth be about 1~ About 800nm, about 1~about 500nm, about 1~about 300nm, about 1~about 250nm, about 30~about 800nm, about 30~about 500nm, about 30~about 300nm, about 30~about 250nm, preferably approximately 50~about 250nm, more preferably from about 50~about 150nm.
In the present invention, the aperture for the nanofilter of the changing regulator of natural inflow mouth be about 3~about 15 μm, preferably approximately 5~about 7 μm.
For nanofilter, pressure can be adjusted by balanced aperture and fibre diameter in those skilled in the art Loss and small substance arresting efficiency preferred embodiment in, nanofilter of the invention have about 50~about The fibre diameter of 150nm and about 3~about 15 μm of aperture.
The nanofilter of the present invention can be formed by any materials.As this material, polytetrafluoroethylene (PTFE) can be enumerated (PTFE), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT) (PBT), polyamide (PA), polyacrylonitrile (PAN), polyvinyladine floride (PVdF), polyvinyl alcohol (PVA), polyurethane (PU) etc., but It is without being limited thereto.In a preferred embodiment, nanofilter of the invention can be made of PTFE.
The nanofilter of the present invention can have the supporting layer of aeration in the above and/or below as needed.This The nanofilter of invention can also be further equipped with the second filter layer.
The thickness of the nanofilter of the present invention can be about 3~about 50 μm, more preferably from about 3~about 20 μm, Further preferably about 3~about 10 μm.For example, although known can use glass fibers in the higher filter of arresting efficiency Dimension, still, the thickness of this filter is mostly more than 100 μm.From the aspect of the appearance of changing regulator, preferably relatively thin side Case.
In the present invention, nanofilter can be cladded with to existing indoor air-changing adjuster and is installed on the third ventilation With on indoor air-changing device, to provide arresting efficiency and the excellent changing regulator of the pressure loss.Thereby, it is possible to much Have and high-performance filter is simply installed on building.

The rotation axis A3 configurations in push-pads portion 56 are on axis of the connection rotation fixed part 56b1 with rotation fixed part 56c1.It pushes away The difference on X and front-rear direction Y in left and right directions is arranged in the rotation axis A3 in tabletting portion 56 and the rotation axis A1 of the first wing body 53 Position.Especially in this second embodiment, the rotation axis A3 in push-pads portion 56 is configured to the first wing body of ratio on front-rear direction Y 53 rotation axis A1 is closer to indoor, also, in left and right directions on X closer to the peripheral side of insertion tube 52.
(operating method when being in an open state changing regulator from closed state setting illustrates)
First, 8 illustrate the operation for opening ventilating path R referring to Fig.1.First wing body 53 and the second wing body 54 are in Operation portion 56c2 is rotated operation (arrow P1) by the changing regulator 51 for the closed state that ventilating path R is closed to opening direction. As a result, push-pads portion 56 to opening direction rotate, pressing portion 56a by the fin 53c for the first wing body 53 being closed to Outside pushes (arrow P2).If the first wing body 53 shaft rotation centered on rotation axis A1 is dynamic, the peripheral side of the first wing body 53 Portion 53A enters the inside of insertion tube 52, and central side 53B gets in side.But on the left and right directions X of central side 53B Length is formed as shorter than the length on the left and right directions X of periphery side 53A, and therefore, the overhang to indoor is shorter.As a result, The change of first wing body 53 is in an open state.
As described above, the rotation axis A3 configurations in the rotation axis A1 of the first wing body 53 and push-pads portion 56 in left and right directions X with And the different location on front-rear direction Y.Therefore, with the rotation of push-pads portion 56 and the first wing body 53, push-pads portion 56 Pressing portion 56a relative in the first wing body 53 in left and right directions X from the periphery side of insertion tube 52 to central side position offset.But It is that maintaining part 53d is formed as X longer in left-right direction, movable gap 53e is again formed as X longer in left-right direction, therefore, i.e., Make pressing portion 56a relative to 53 position offset of the first wing body, also can allow for its position offset and continues to keep pressing portion 56a.
Connection sheet portion 55 is pushed by the first wing body 53 and rotates, and first axle supporting part 55a moves (arrow P3) to outside.With This simultaneously, second be pivotally supported portion 55b to indoor move, by the central side 54B of the second wing body 54 to indoor pull (arrow P4).The periphery side 54A of the second wing body 54 is rotated to outside as a result, and the change of the second wing body 54 is in an open state (arrow P5). Length on the left and right directions X of central side 54B is similarly formed as the left and right directions X than periphery side 54A with the first wing body 53 On length it is short, therefore, the overhang to indoor is shorter.The first wing body 53 and the second wing body under opening state as a result, 54 overhang to indoor is shorter, can constitute the changing regulator 51 for not interfering with indoor beauty.
As described above, forming inside the first protrusion 53d1 outstanding of oriented movable gap 53e in maintaining part 53d.It is inciting somebody to action When operation portion 56c2 is moved to opening state from closed state, pressing portion 56a can be made to move and be fixed in movable gap 53e More than the position of the first protrusion 53d1.In this way, push-pads portion 56 is fixed on open position, the first wing body 53, connection sheet portion 55, And second wing body 54 be also held between opening state.In addition, when operator makes pressing portion 56a inside movable gap 53e When moving through the first protrusion 53d1, shock sense can be felt on hand, therefore, it is possible to reliably be carried out by feel confirmation Fixation.
As described above, push-pads portion 56, the first wing body 53, connection sheet portion 55 and the second wing body 54 almost conjugate simultaneously. Thus, it is only necessary to pass through this shirtsleeve operations of rotating operating unit 56c2, it will be able to simply make the first wing body 53 and second Wing body 54 is opened as clamshell doors.Ventilating path R is opened under the opening state, can fully be taken a breath.
(operating method explanation when changing regulator is set to off closed state from opening state)
In the following, 9 illustrating the operation for closing ventilating path R referring to Fig.1.First wing body 53 and the second wing body 54 are in Operation portion 56c2 is rotated operation (arrow C1) by the changing regulator 51 for the opening state that ventilating path R is opened to closing direction. In this way, push-pads portion 56 is rotated to closing direction, pressing portion 56a is by the maintaining part 53d of the first wing body 53 in the open state It is pushed in a manner of being pulled to closing direction.As a result, if the first wing body 53 shaft rotation centered on rotation axis A1 is dynamic, first wing The periphery side 53A of body 53 moves (arrow C2) to indoor, and central side 53B is moved to 52 side of insertion tube.In this way, first wing The change of body 53 is in off state.
In the case where operation is from opening state to closed state, with phase the case where operation from off state to opening state Instead, with the rotation of push-pads portion 56 and the first wing body 53, the pressing portion 56a in push-pads portion 56 exists relative to the first wing body 53 From the central side of insertion tube 52 position offset to outer peripheral side on left and right directions X.But maintaining part 53d allows this offset and holds Pressing portion 56a is held in continuation of insurance.

(embodiment)
(embodiment 1：Use the pressure loss research of the changing regulator of nanofiber)
The existing air inlet rebreather of electrostatic filter be will be provided with as usually used changing regulator and had respectively The air inlet rebreather setting of two kinds of nanofiber prefilters of the standby present invention measures the airborne measurements pressure loss in the pressure loss.Base Measurement method recorded in the annex 1 of JIS C9603 (ventilation fan) carries out the measurement of the pressure loss.Pressure loss measuring machine is such as Shown in Figure 25, measuring mouth (conduit) is connect with the changing regulator measured in a manner of not leakage air.With changing regulator The diameter of measuring mouth, that is, conduit of connection has the ventilation size of mouth of changing regulator identical with actual installation.In this measurement In, measuring mouth, that is, conduit diameter isRestricting orifice appropriate can be selected according to air quantity.It is arranged for making The adjusting aerodynamic-laid web and expansion aerofoil of wind speed homogenization in air groove.Air quantity adjusting is carried out by power controller.When measurement, It is adjusted so that after the static pressure of air groove (static pressure is made to be 0) equal with the static pressure when air quantity for measuring changing regulator, leads to Cross recorder (for example, (strain formula) hilllock open country makes produced pressure gauge) the reading air groove and measurement pipeline for measuring air quantity Pressure difference.
In actually measuring, first, the air quantity-of the changing regulator and measuring mouth connection status (state 1) of measurement is found out Static pressure curve.Then, the air volume-static pressure curve for the state (state 2) that changing regulator is removed from measuring mouth is found out.Then, Pressure loss curve is calculated by the difference of the air volume-static pressure curve of the air volume-static pressure curve and state 2 of state 1.It is measuring In, static pressure measurement to 100Pa.In addition, in the present specification, pressure drop coefficient ζ is calculated by formula below.
ζ=δ P × ((4.03 × catheter section product)/air quantity)) ^2
δ P are the pressure differences of recorder record.
Its result is indicated in Figure 22.
For existing electrostatic filter, measure setup in two kinds of different frameworks designs the pressure loss (A of Figure 22 and B).Although as can be seen that being identical electrostatic filter, since framework designs difference, compared with A, the pressure loss of B is less (that is, when for example applying identical static pressure 100Pa, compared with A, the gas transit dose of B is more).
Two kinds of nanofilters are set in framework design (B of Figure 22) the identical framework less with the pressure loss.Figure 22 C1, C2 and C3 is in nanofilter (the day east electrician strain that fibre diameter is about 125nm, aperture is about 10 μm Formula commercial firm, Osaka, Japan) on respectively by the ridge of fold away from being set as about 8mm (C1), about 6mm (C2), about 4mm (C3) The case where.D1, D2 and D3 of Figure 22 is that (day is eastern in the nanofilter that fibre diameter is about 60nm, aperture is about 5 μm Electrician Co., Ltd., Osaka, Japan) on respectively by crest of fold away from being set as about 8mm (D1), about 6mm (D2), about 4mm (D3) the case where.The ridge height of the fold of D1, D2, D3 is about 15mm.
It merits attention, between the changing regulator and C1~C3 of A, B and the changing regulator of D1~D3, trapping There are larger differences for efficiency.That is, the changing regulator of A and B is at most to the arresting efficiency of the particle of 0.5~1.0 μm of grain size 46.3%, in contrast, the arresting efficiency of the changing regulator of C1~C3 and D1~D3 is obviously more excellent, for example, grain size For 0.3 μm of particle arresting efficiency more than 70%.C1~C3 (fibre diameter is about 125nm, aperture is about 10 μm) And in D1~D3 (fibre diameter is about 60nm, aperture is about 5 μm), the arresting efficiency of D1~D3 is more excellent.
Moreover, the pressure loss of B and the pressure loss of C1 and D1 do not change, the pressure of C2, C3, D2 and D3 Loss is more than the pressure loss of B.That is, the pressure drop coefficient that the pressure drop coefficient of existing product, that is, A is 178.8, B is 45.55, in contrast, pressure drop coefficient is respectively：C1 is 54.5, C2 37.39, and C3 29.98, D1 42.76, D2 are 34.9, D3 26.12.
These results are very unexpected in the art, and the data of Figure 22, which have been explicitly shown, to be considered being not used to The nanofilter of natural inflow changing regulator is suitable for the possibility of changing regulator.Importantly, the tendency will not Change with air quantity, no matter how air quantity all shows the situation always.It can be right suitable for requirement in addition, having also demonstrated nanofilter The possibility of the changing regulator of the third air exchange system of air quantity should significantly be changed.
Furthermore, it is desirable to be noted that, it is consistently observed this tendency：The spacing of fold is reduced to about 8mm, about 6mm, about 4mm will increase the pressure loss.
(embodiment 2：The pressure loss and arresting efficiency research of the nanofilter with other filters)
Confirm that the fibre diameter used in embodiment 1 is about 60nm, is incited somebody to action in the nanofilter that aperture is about 5 μm Fold spacing is set as about 4mm, ridge high setting is about 15mm filter, the existing electrostatic mistake being arranged in identical framework Filter (not carrying out crimped working process) and with radial microstrainer (the Panasonic Ecology for carrying out crimped processing The filter VB-YA100PM of Systems Co., Ltd. manufacture：About 15 μm~about 46 μm of fibre diameter) the pressure loss with And arresting efficiency changes with time.
The A of Figure 23 is the nanofilter changing regulator (A1 is initial value, and A2 is after 40 hours) of the present invention, B Existing microstrainer (B1 is initial value, and B2 is after 30 hours), C be existing electrostatic filter (C1 is initial value, C2 be through After spending 30 hours).Figure 23 A indicate that the pressure loss changes with time, and Figure 23 B indicate the comparison of arresting efficiency.
As the pressure loss, pass through digital pressure gauge (Star Network バ リ カ セ イ キ in measurement object object, that is, filter unit The pressure gauge (F-213) of Co., Ltd.'s manufacture) measure the pressure of filter upstream and downstream when passing through air with the air quantity of 2.5 meter per seconds Difference.
In the nanofilter changing regulator of the present invention, the arresting efficiency of 0.3~0.5 μm of dust is more than 70%, separately Outside, the pressure loss changed over time is observed, is portrayed as the smaller curve of the gradient, it is seen that be suitable for commercial use.Microstrainer ratio The pressure loss of electrostatic filter is big, is not suitable for the changing regulator of natural inflow mouth.

For arresting efficiency, the average value of 4 measurements is recorded.Experiment dust：House dust
In addition, for the initial value (B1) of microstrainer, it is contemplated that leaked between framework and filter.And And as time goes by, attaching particles etc. in micrometer fibers can improve the loophole between micrometer fibers, improve arresting efficiency.This Afterwards, as time goes by, advance ratio other filters that the particle adhered in the micrometer fibers of microstrainer blocks are fast, the longevity Life is shorter.
(embodiment 3：Ridge height is studied)
The results of the research and development of inventor according to the present invention it is found that in order to improve the pressure loss of nanofilter, The condition of crimped processing is important.
In the present embodiment, spacing about 4mm, the nanofilter of ridge height about 15mm and spacing are measured about The pressure loss of the nanofilter of 4mm, ridge height about 25mm.
As a result as shown in figure 24.A indicates that spacing about 4mm spacing, ridge height about 15mm, back space about 5mm are changed Gas adjuster, B indicate that spacing is the changing regulator of about 4mm, crimp height about 25mm, back space about 5mm.
According to the result of A and B it is found that the developed area of the larger nanofilter of ridge height is more, pressure can be improved Loss.
(embodiment 4：Durability)
In practice, the nanofilter of fibre diameter about 60nm, about 5 μm of aperture are installed in the family of inventor, Using measuring the pressure loss after 1 month.According to its result it is found that reducing by 6% or so due to blocking air mass flow.
