On inner surface 11i, 21i, 31i of housing 11,21,31, it is fixed with using fixing member 12,22,32 anti- Water is breathed freely (entrant sound) film 13,23,33, with closure opening 15,25,35.In the portable electric appts 10,30 shown in Fig. 1 and Fig. 3 In, opening 15,35 is arranged on the interarea of housing 11,31, and in the portable electric appts 20 shown in Fig. 2, opening 23 is arranged on housing 21 side 21s.The size of opening 15,25 is not particularly limited, but is normally constrained to small, for example, 100mm²Hereinafter, It is further 75mm²Hereinafter, specifically for 50mm²Hereinafter, in particular 20mm²Hereinafter, also, for example, 0.5mm²More than, specifically for 1.0mm²More than.The shape of opening is it is not also specifically limited, the shape of the opening 15,25,35 at the surface of housing is, for example, to justify Shape, ellipse or rectangle, are typically the case circle.

Fixing member 12,22,32 is preferably double-faced adhesive tape but it is also possible to be the layer for being directly coated with bonding agent and being formed Deng.Fixing member 12,22,32 is preferably cricoid component, and with its periphery and waterproof and breathable (entrant sound) film 13,23,33 The mode that the periphery of interarea matches configures.In this case, waterproof is limited using the inner circumferential of fixing member 12,22,32 The vapor permeation area or entrant sound area of ventilative (entrant sound) film 13,23,33.

Waterproof and breathable (entrant sound) film 13,23,33 is to play airing function and/or entrant sound function and prevent water from entering in housing The film of the water resistance in portion.Even as described above, embody the film of airing function and entrant sound function the two functions, for convenience, Sometimes referred to as waterproof ventilated membrane or waterproof sound passing membrane.Representational waterproof and breathable (entrant sound) film is fluororesin perforated membrane, special It is not polytetrafluoroethylene (PTFE) (PTFE) perforated membrane.PTFE perforated membranes both can be used alone, can also as with non-woven fabrics, mesh And other reinforcement materials layered products for being mutually laminated uses.

For PTFE perforated membranes, can also implement to refuse oil processing using oil-repellent agent.Oil processing is refused as that can be used in Oil-repellent agent, in general, be applicable in using linear perfluoroalkyl as representative, at least a portion containing wherein hydrogen atom taken by fluorine atom The fluoropolymer of alkyl after generation.The Japan that specific oil-repellent agent is for example disclosed in the applicant with the method for refusing oil processing is special Open in 2014-42878 publications, Japanese Unexamined Patent Publication 2012-236188 publications.

Waterproof and breathable (entrant sound) film 13,23,33 is not limited to PTFE perforated membranes, can use for the purposes or suggest The various films used, such as non-woven fabrics, foamed resin, the resin film (resin film) etc. with through hole.It is suitably used and refuses Aqua or oil-repellent agent handle these films.Resin film with through hole can for example be made by the following method：Using from Beamlet irradiation etc. forms small damage field, comes to form hole along the region followed by etching.The resin film becomes phase Mutually independent multiple straight holes penetrate into the film at the back side from surface.The detailed content of resin film (resin film) with through hole is for example It is disclosed in No. 5711412 publications of Japanese Patent Publication No. of the applicant.

As described above, in general, waterproof and breathable (entrant sound) film 13,23,33 is perforated membrane.But requiring nothing more than entrant sound work( In the case of energy, film 13,23,33 can also be non-porous film.Propagated as the waterproof sound passing membrane of non-porous film using vibration of membrane Sound wave, thus embodies entrant sound function.

In Fig. 1~Fig. 3, the single opening 15,25,35 of the closure of single waterproof and breathable (entrant sound) film 13,23,33 is configured to, But multiple openings can also be blocked using single waterproof and breathable (entrant sound) film.Alternatively, it is also possible to be it is multiple opening it is different Waterproof and breathable (entrant sound) film covers.

Specifically, portable electric appts 10,20,30 are wearable terminal, mobile phone, smart phone, tablet Computer, laptop, digital camera, portable game machine, portable music player, IC loggers etc. have and can carry Degree size electronic equipment.Portable electric appts 10,20,30 can also have wheat in the inside of housing 11,21,31 The converters such as gram wind, loudspeaker.

Make waterproof and breathable (entrant sound) film 13,23,33 and product that fixing member 12,22,32 advance integrations form is (anti- Water is breathed freely (entrant sound) component 18,28,38) it is easy to install to housing 11,21,31.As shown in figure 3, waterproof and breathable (entrant sound) component 38 can also be that fixing member 32,34 is configured at the component that two interareas of waterproof and breathable (entrant sound) film 33 form.It is fixed It is, for example, to be used in order to which the internals 39 such as waterproof and breathable (entrant sound) film 33 and converter are joined together with component 34.

In addition, in the state of shown in Fig. 1~Fig. 3, the outer surface of the encirclement opening 15,25,35 of housing 11,21,31 Normal vector P1, P2, P3 of 11o, 21o, 31o are towards (P1, P3) above horizontal direction H (P2) or vertical V.Table on the outside In the case that face is not plane, normal vector can be determined according to the outer surface in the position contacted with opening.

(cleaning method)

The cleaning of portable electric appts can be implemented in the following manner：First, using containing surfactant 1st cleaning solution cleans the outer surface of portable electric appts (step (II)), afterwards, is lived using surface is contained substantially no 2nd cleaning solution of property agent cleans waterproof and breathable (entrant sound) film (step (III)).

Contain surfactant in the 1st cleaning solution.The species of surfactant has no particular limits, and both can be the moon Any one in ionic surface active agent, cationic surfactant, amphoteric surfactant, nonionic surfactant, Can also be optional a variety of from these surfactants.As the 1st cleaning solution, such as, it is convenient that using as Tableware surfactant, clothes surfactant, house surfactant etc. and commercially available liquid detergent.1st is clear Washing lotion can also be the soap shampoo class such as shower cream, hand cleanser, shampoo.In addition, the 1st cleaning solution, which can also include, comes from block The surfactant of solid formulation as soap, soap powder.The liquid component (solvent) of 1st cleaning solution is preferably water.

As the 1st cleaning solution, commercially available product both can be directly used, can also prepare for implementation steps (II) and modulate Cleaning solution, surfactant and water equal solvent can also be supplied and form the 1st cleaning on the surface to the surface of housing respectively Liquid.

The concentration of surfactant in 1st cleaning solution is not particularly limited, with weight basis, be, for example, 0.05% with On, it is further more than 0.1%, specifically for more than 1%, also, for example, less than 100%, specifically for less than 90%.

2nd cleaning solution contains substantially no surfactant.Here, " containing substantially no " is it is meant that allow to exist not (entrant sound) film that can breathe freely to self waterproofing removes the micro surfactant that surfactant produces the degree hindered, it is specific and Speech, with weight basis, the containing ratio of the surfactant in the 2nd cleaning solution is less than 0.01%, especially less than 0.001%. The surfactant contained by small drop to disperse in step (II) is possible to finger tip via people, the surface of electronic equipment Etc. being mixed into the 2nd cleaning solution, it is mixed into even if generating the micro of the degree, the containing ratio of surfactant also terminates in State degree.Micro if the degree is mixed into, then will not be to the purpose from the such step (III) of film removal surfactant Realization produce obstruction.

2nd cleaning solution is typically water.The water that is used in the 1st cleaning solution and the 2nd cleaning solution either tap water, Can be water as ion exchange water after purification.

In step (II), allow the 1st cleaning solution to be contacted with waterproof and breathable (entrant sound) film, and come clearly using the 1st cleaning solution Wash the outer surface of portable electric appts.Step (II) and the degree of the dirt that should be removed of electronic equipment are correspondingly appropriate real Apply, so that its dirt is removed preferably, its specific form has no particular limits.Step (II) can be without using adhesive tape Implement in the case of covering opening Deng component.

Step (III) if cleaning with the 1st cleaning solution contacts with waterproof and breathable (entrant sound) film and to be in step (II) before Carry to implement.That is, step (III) can in not to step (II) the 1st cleaning solution whether with waterproof and breathable (entrant sound) film Contact is implemented in the case of being confirmed.Set if so, then after step (II), can promptly start step (III)。

Step (III) is implemented to remove the 1st cleaning solution for being possible to residue in waterproof and breathable (entrant sound) film.Its Separated out the reason is that, working as by the solvent components of representative of the surfactant in the 1st cleaning solution on waterproof and breathable (entrant sound) film When, the characteristic of film can be made reduce.The precipitate of surfactant etc. forms water in the inside of waterproof and breathable (entrant sound) film sometimes The path passed through or the starting point as path, so that the water resistance of film reduces.Will be saturating in waterproof ventilated membrane in addition, also existing Gas route locking and make gas permeability, sound transparency reduce situation.The precipitation to non-porous sound passing membrane such as surfactant also can be into The reason for hinder vibration of membrane to reduce its sound transparency.In addition, in the 1st cleaning solution, however it is not limited to which surfactant, has When also containing the other compositions such as stabilizer, other compositions are also analysed with surfactant together as residue sometimes in this case Go out.

The research of people according to the present invention, the surfactant temporarily precipitateing on waterproof and breathable (entrant sound) film are not easy to lead to Over cleaning removes.Thus, step (III) preferably after implementation steps (II) and is in waterproof and breathable in surfactant Come into effect before the degree for being difficult to remove is precipitate on (entrant sound) film.Specifically, step (III) is after step (II) And it is by being come into effect before predetermined time td.Time td is the upper limit of time, which is suitable for suppressing because to dissolve It precipitate on waterproof and breathable (entrant sound) film and leads in the surfactant of waterproof and breathable (entrant sound) film in the state contacts of cleaning solution Cause the reduction of at least one characteristic selected in slave water resistance, gas permeability and the sound transparency of the film.It is desirable that, time td is tight The individually setting in advance according to construction near the openings of portable electric appts etc. of lattice ground.But no matter due to portable electric The species of sub- equipment how near opening structurally there are more identical point (with reference to Fig. 1~Fig. 3), therefore, it is possible to describe The time td that it is generally desirable to.

Reasonable time td exists with the ring that waterproof and breathable (entrant sound) film is kept between step (II) and step (III) The tendency that the temperature in border rises and shortens.Also allow for since cleaning is implemented indoors mostly, only preset room temperature (25 DEG C) temperature as environment.But when being redefined for being higher than room temperature by the upper limit of the temperature of environment, can be more reliably Preventing the characteristic of the film caused by the precipitation of surfactant reduces.Such as to beginning step after completion step (II) is made (III) in the case that the temperature of the environment of holding waterproof and breathable (entrant sound) film is less than 35 DEG C in a period of untill, the time, td was excellent Choosing is redefined for 20 minutes, is further preferably redefined for 10 minutes.In addition, make the temperature of above-mentioned environment for 40 DEG C with In the case of lower, time td is preferably redefined for 10 minutes, is further preferably redefined for 5 minutes.

Operation for cleaning portable electric appts in the environment of more than 40 DEG C, its chance implemented in reality are Limited, and also worry to impact electronic component in portable electric appts etc., therefore should also be as avoiding.Time td is only To be directed to the environment temperature of above-mentioned degree (less than 40 DEG C) and preset, in practical with regard to it is enough, if desired further directed to High temperature and preset, then can also be, with after for example completing step (II) untill beginning step (III) in a period of It is object to keep the situation that the temperature of the environment of waterproof and breathable (entrant sound) film is less than 60 DEG C, and time td is redefined for 1 point Clock, is especially redefined for 30 seconds.In addition, in inspection method described later, can be in the feelings without using portable electric appts Implement each step under condition, therefore, even if making above-mentioned environment be high temperature, electronic component etc. will not be impacted, thus, even if The upper limit of the temperature of environment is set as 60 DEG C, it is unfavorable to produce.

In the case of the environment temperature of the unmanageable cleaning for carrying out portable electric appts or because other people carry out clearly Wash and be intended in the case of avoiding specifying, it may be desirable to be set to time td shorter.Do not limit in the case of environment temperature when Between td be, for example, 1 minute, be further 30 seconds, specifically for 20 seconds.In this case, object, the allusion quotation for that may implement to clean The situation of type is user, the sellers of portable electric appts, on the transition from step (II) to step (III), is not carried Waking up, it pays attention to the limitation of environment temperature, as long as only prenoticing them needs to lose no time to carry out " to implement to utilize the clear of detergent Wash after (step (II)), begin to use water (at the latest within 1 minute) immediately to clean film (step (III)) " etc. film it is clear Wash.In this case, as long as the object for implementing cleaning also only pays attention to the time.

In step (III), in order to remove surfactant, it is desirable to make cleaning solution with sufficient time and waterproof Ventilative (entrant sound) film contact.The reason is that surfactant is because of the presence in its oleophylic portion (hydrophobic group) and with utilizing hydrophobicity Material and be endowed waterproof and breathable (entrant sound) film of water resistance or waterproof and breathable (entrant sound) film formed by hydrophobic material Between original compatibility it is higher.Thus, the time tw of the 2nd cleaning solution of supply is preferably more than 15 seconds in step (III), More preferably more than 20 seconds, more preferably more than 30 seconds, particularly preferably more than 60 seconds.The time of implementation steps (III) The upper limit be not particularly limited, but in general, it is enough for less than 5 minutes the implementation time of step (III).

It will attach to the cleaning for the degree that dust of the outer surface of portable electric appts etc. lightly washes away with flowing water E insufficient to by surfactant self waterproofing breathe freely (entrant sound) film remove.The cleaning for the degree that the dirt easily removed is washed away is led to Often just terminate in or so several seconds, and flowing water is not necessarily supplied to the opening for leading to waterproof and breathable (entrant sound) film.In addition, for example exist The 1st cleaning solution that sponge contains is set to blister while, it is necessary to continue portable to residuing in the case of implementation steps (II) The foam of the outer surface of electronic equipment is rinsed, even if implementing the flushing, also due to it is same as described above the reason for, flowing water Do not supply that (in this case, the water of flushing contains a great deal of to the opening for leading to waterproof and breathable (entrant sound) film with the sufficient time Surfactant, therefore, even if the water is supplied to film, it is also difficult to from film remove surfactant).For step (III), It is different come the action implemented from using flushing as described above, it is preferred that on one side so that the liquid stream of the 2nd cleaning solution reaches housing Opening mode keep portable electric appts posture (not making portable electric appts exceedingly move) while implement step Suddenly (III).

In step (III), in order to suitably clean waterproof and breathable (entrant sound) film, it is necessary to corresponding according to the position of opening Ground suitably sets the posture of portable electric appts.In step (III), in order to lead to waterproof and breathable (entrant sound) film 13,23, 33 opening 15,25,35 supplies the 2nd cleaning solution, so that outer surface 11o, 21o, 31o of the encirclement opening 15,25,35 of housing Normal vector P1, P2, P3 are towards horizontal direction H or towards keeping portable electronic than horizontal direction mode by the top Equipment 10,20,30.The reason is that when being set as making normal vector towards than horizontal direction H states on the lower, the 2nd cleaning Liquid is difficult to supply to waterproof and breathable (entrant sound) film from opening, moreover, the 2nd cleaning solution is difficult to be maintained at waterproof and breathable (entrant sound) film Between opening.

As shown in figure 4, it is set as while from such as tap i.e. cleaning solution supplying device 50 to the portable electric shown in Fig. 1 Sub- equipment 10 supplies such as 5 one side implementation steps (III) of i.e. the 2nd cleaning solution of tap water.In this case, it is portable in order to clean Waterproof and breathable (entrant sound) film 13 of electronic equipment 10, it is desirable to which position A is located at without positioned at position B, C or D with opening 15 Mode sets and keeps the posture of portable electric appts 10 in an atmosphere.If the position of opening 15 is set and is held in position A, then can using as the water 5 of the 2nd cleaning solution with the scheduled time (such as more than 20 seconds) stably to waterproof and breathable (entrant sound) film Supply.In addition, the 2nd cleaning solution 5 that point UM is located at the supply of self-cleaning liquid supplying device 50 is fed directly to portable electronic and sets The upper end (in Figure 5 and same) in the region of standby 10 outer surface and be the position than position A (J) by the top.

Desired opening 25 for waterproof and breathable (entrant sound) film 23 for cleaning the portable electric appts 20 shown in Fig. 2 Position is not any one in position E, F.In order to clean waterproof and breathable (entrant sound) film 23, if setting as shown in Figure 5 Portable electric appts 20 relative to cleaning solution supplying device 50 posture and opening 25 is located at position J (not positioned at position K), then the 2nd cleaning solution 5 can be made stably to reach opening 25, and then can suitably clean waterproof and breathable (entrant sound) film 23.This Outside, in Figure 5, portable electric appts 20 proceed as follows holding, i.e. make the side 21s equipped with opening 25 relative to Its long side direction tilts, and the 2nd cleaning solution 5 is flowed along side 21s from point UM towards the opening 25 positioned at position J.

In step (III), the 2nd cleaning solution 5 is supplied in a manner of the liquid stream for making the 2nd cleaning solution 5 reaches opening 15,25. Reach the 2nd cleaning solution 5 of opening 15,25, in general, one part can enter opening 15,25 and with waterproof and breathable (entrant sound) film 13rd, 23 contact.But even if it is not that the 2nd cleaning solution 5 for reaching opening 15,25 fully enters the 15,25, the 2nd cleaning solution of opening The master that 5 liquid stream also becomes the 2nd cleaning solution 5 in contact openings 15,25 and causes the 2nd cleaning solution 5 in opening 15,25 to move Want reason.The 2nd cleaning solution 5 for reaching opening 15,25 is directly entered in opening 15,25, or be introduced into opening 15,25 and The 2nd cleaning solution 5 in opening 15,25 is moved, and according to circumstances circulates the 2nd cleaning solution 5 in opening 15,25, thus The liquid stream of 2nd cleaning solution 5 can clean waterproof and breathable (entrant sound) film 13,23.On the other hand, when portable electric appts are set as soaking Stain and when resting on the form in the 2nd cleaning solution, because of the difference of the posture of portable electric appts, there are gas bubbles left in opening Inside and the 2nd cleaning solution can not be fully contacted with the hidden danger of waterproof and breathable (entrant sound) film, even if bubble does not remain, the 2nd Cleaning solution is also difficult to circulate in opening.Therefore, it is impossible to fully obtain the cleaning performance of the 2nd cleaning solution.

The experiment implemented in the state of the object of experiment is stood in a liquid is in waterproof and breathable (entrant sound) film The known method used in watertight measurement etc..But for cleaning, if not so that the 2nd cleaning solution relative to lead to make Opening for waterproof and breathable (entrant sound) film of the object of cleaning relatively moves and it is reached the liquid stream of opening to supply the 2nd Cleaning solution, then can not be appropriately carried out cleaning.

It is different from the form shown in Fig. 4 and Fig. 5, can also be by the 2nd cleaning solution from its feedway in step (III) Directly fed to opening.But it is more preferable to as shown in Figure 4 and Figure 5, the 2nd cleaning solution 5 is supplied to the outer surface of housing Give, the 2nd cleaning solution 5 is become the liquid stream for flowing along the outer surface and being contacted with opening 15,25, more specifically as one side The liquid stream that an edge outer surface further falls downwards is contacted with opening 15,25.The preferred configuration is suitable for saturating to waterproof The 2nd cleaning solution 5 is stably supplied in gas (entrant sound) film 13,23.

Supplied by the 2nd cleaning solution 5 in a manner of being flowed on outer surface 11o, 21o in housing to opening 15,25 In the case of, normal vector P1, P2 of outer surface 11o, 21o of the encirclement opening 15,25 of housing and towards in vertical The vector v angulations θ of side is preferably more than 10 °, particularly preferably more than 20 °, also, preferably less than 80 °, especially excellent Elect less than 75 ° as.It is not horizontal (θ=0 °) by making outer surface 11o, 21o, but is slightly tilted, the 2nd cleaning solution 5 is easy The circulation in opening 15,25, and can expect the effect that waterproof and breathable (entrant sound) film 13,23 is efficiently cleaned.

In addition, as shown in Figure 4 and Figure 5, the 2nd is released on the lower towards than horizontal direction H in self-cleaning liquid supplying device 50 In the case of cleaning solution 5, it is preferred that so that opening 15,25 is located at is fed directly to portable electronic than the 2nd ejected wash water 5 The modes of the positions of the upper end UM in the region of outer surface 11o, 21o of the housing of equipment 10,20 on the lower keeps portable Electronic equipment.

In addition, in step (III), the amount q for the 2nd cleaning solution 5 that self-cleaning liquid supplying device 50 supplies is not limited especially System, but more than preferably 100ml/ minutes, more preferably more than 200ml/ minutes, particularly preferably more than 400ml/.For The upper limit to amount q also has no particular limits, but due to also will not substantially improve cleaning even if excessively the 2nd cleaning solution of supply The reason such as effect, therefore by the upper limit of quantity delivered q be set to 10000ml/ minutes it is following preferable.In addition, quantity delivered q be not with The amount of 2nd cleaning solution of waterproof and breathable (entrant sound) film contact, but the outer surface of self-cleaning liquid supplying device towards housing is put The total amount of the 2nd cleaning solution gone out.

(inspection method of waterproof and breathable (entrant sound) film)

By implementing steps described below (Ia), step (IIa), step (IIIa), step (IVa) and step successively (Va), it can check that waterproof and breathable (entrant sound) film is appropriate for use above-mentioned cleaning method.

In step (Ia), the opening will be equivalent to the simulation component of part of housing or housing is fixed in a manner of blocking As waterproof and breathable (entrant sound) film of check object, test body is made.For the fixation of film, for example, can use above-mentioned Fixing member.The structure of the waterproof and breathable construction of simulation portable electric appts or water-proof sound-transmitting construction is formed using test body Make.

Figure 6 illustrates an example of test body.Here, use base as with the corresponding component of the part of housing Body 61.Test body 60 includes：Matrix 61, it is with circular opening 65；Cricoid 1st fixing member 62, it is used for will be anti- Water (entrant sound) film 63 of breathing freely is fixed on matrix 61；And discoideus waterproof and breathable (entrant sound) film 63, use the 1st fixing member 62 fix waterproof and breathable (entrant sound) film 63, and the opening 65 of matrix 61 is blocked.1st fixing member 62 is fixed on matrix 61 The 1st face 61i.Opening 65 contacts external environment condition in matrix 61 with the 2nd face 61o of the 1st face 61i opposite side.In addition, anti- Water is breathed freely being configured with the interarea of 62 opposite side of the 1st fixing member for making to be set as enclosure interior of (entrant sound) film 63 (with 62 same shape of the 1st fixing member) the 2nd that the plate 69 and film 63 of component (such as converter) engage, which is fixed, to be used Component 64.Plate 69 also plays in step (II) and step (III) prevents cleaning solution from the side opposite with opening 65 and film The effect of 63 contacts.Be suitable as simulation component matrix 61 be specifically provided with the resin plate of through hole as opening 65, Metallic plate etc..Wherein, the shape for simulating component is not limited to tabular, as long as comprising being used in actual product 10,20,30 The shape at least near opening 15,25,35 of housing 11,21,31.For fixing member 62,64, using in reality The component or same component used in product 10,20,30 is preferable.

Step (IIa) is to contemplate the 1st cleaning solution in step (II) to contact and implement with waterproof and breathable (entrant sound) film.That is, The step of waterproof and breathable (entrant sound) film is all implemented (II) whether is contacted with relative to the 1st cleaning solution, in step (IIa), So that the 1st cleaning solution supplies the 1st cleaning solution with the mode that waterproof and breathable (entrant sound) film contacts.Specifically, in step (IIa) In, so that via the opening of test body to supply the 1st with the mode that waterproof and breathable (entrant sound) film reliably contacts clear for the 1st cleaning solution Washing lotion.When being illustrated with reference to Fig. 6, in step (IIa), so that 4 self-retaining of the 1st cleaning solution containing surfactant has 2nd face 61o sides of the matrix 61 of waterproof and breathable (entrant sound) film 63 and the mode that waterproof and breathable (entrant sound) film 63 contacts supply containing 1st cleaning solution 4 of surfactant.

Step (IIa) so that surround opening 65 outer surface 61o normal vector P6 towards horizontal direction H or towards than Horizontal direction H modes by the top, preferably by make normal vector P6 along vertical V upward in a manner of remain experiment Implement in the state of body 60 preferable.

In step (IIa), make the 1st cleaning solution 4 with thinking that the 1st cleaning solution 4 may contact waterproof in step (II) The time same degree of ventilative (entrant sound) film 63 or the time longer than the time contact preferably with waterproof and breathable (entrant sound) film 63. It is preferably for example more than 5 seconds the 1st cleaning solution 4 is contacted with the time tc of waterproof and breathable (entrant sound) film 6 in step (IIa), into one Step preferably more than 10 seconds, particularly preferred more than 30 seconds, and such as preferably less than 5 minutes, particularly preferred less than 3 minutes.

In step (IIa), in order to make the 1st cleaning solution 4 reliably be contacted with waterproof and breathable (entrant sound) film 63, preferably It is the 1st cleaning solution 4 is dripped into opening 65 using the cleaning solution such as microsyringe, micropipette injection device 40.It is adapted to The 1st cleaning solution 4 used is as described above.In addition, in the case where using commercially available detergent as the 1st cleaning solution 4, moreover it is possible to Enough situations that it is contemplated that in actual cleaning process, commercially available detergent is used in the case where not being diluted with water, therefore, It can also be used in the case where not diluting detergent in a manner of stoste.

Except supplying the 2nd cleaning solution via the opening 65 of the matrix 61 as simulation component not via the opening of housing Outside, can be with implementation steps (IIIa) in the same manner as step (III).In inspection method, step (IIIa) is in step (IIa) After, specifically tilt matrix 61 and make the 1st cleaning solution 4 from opening 65 outflow after have passed through set in advance when Between tv when start.Time tv is from the range set for being directed to below the time td that cleaning method is set, but it is preferred that setting in advance It is set to the time identical with time td.For example, in a period of after making completion step (IIa) untill step (IIIa) is started The temperature of environment be less than 35 DEG C and make in the case that time td is 20 minutes that what time tv can be for less than 20 minutes is predetermined Time, but be preferably set to 20 minutes.Limit 1 minute as no matter the time td that the temperature of above-mentioned environment can be applied In the case of, time tv can also be set as less than 1 minute, but be preferably set to 1 minute.For being adapted to be used in step (IIIa) the 2nd cleaning solution in, it is also described above.

It is desirable that, in a period of after completing step (IIIa) untill step (IVa) is started, make waterproof and breathable (entrant sound) film is dried.Preferably, which is implemented in a manner of removing moisture removal completely from film.As long as specific drying condition Correspondingly suitably set according to film, natural drying (air-dried) can also be only relied on, but be intended to make waterproof and breathable in the short time In the case that (entrant sound) film is dried, additionally it is possible to be set as keeping condition as 30 minutes in such as 60 DEG C of environment.

In step (IVa), such as to selected from water resistance, gas permeability and sound transparency, waterproof and breathable (entrant sound) At least one kind of characteristic of film measures, and preferably at least measures water resistance.As long as these characteristics were using from the past can just implementing Measuring method measures, its specific method measured is not particularly limited.Step (IVa) both can be by waterproof Ventilative (entrant sound) film 63 is implemented in the state of being fixed on matrix 61, can also be torn open by waterproof and breathable (entrant sound) film 63 from matrix 61 Implement after lower.

As water resistance, fastness to water experiment B methods (high hydrostatic(al) process) measurement based on JIS L1092 defineds can be illustrated Water pressure resistance.As gas permeability, the B methods (Ge Erlaifa) that can illustrate the permeability measurement method based on JIS L1096 defineds are surveyed The air permeability of amount.Another example of gas permeability is the A method (fraziers of the permeability measurement method based on JIS L1096 defineds Method) measurement air permeability.As sound transparency, it can illustrate and commercially available sound equipment evaluating apparatus can be used (for example, B＆K systems, Multi- Analyzer System3560-B-030) measure acoustic pressure loss (insertion loss).The damage of the device has been used to enter loss Measuring method be disclosed in for example above-mentioned No. 5711412 publications of Japanese Patent Publication No..

After measuring the measured value D1 of the characteristics such as water resistance in step (IVa), implement the result based on step (IVa) To judge the whether qualified step (Va) of waterproof and breathable (entrant sound) film.For step (Va), for example, by measured value D1 and implementing The measured value D0 of the characteristic measured before step (IIa) for waterproof and breathable (entrant sound) film is counted according to predetermined calculating formula Parameter R1 is calculated, can be based on parameter R1 come implementation steps (Va).The calculating formula of calculating parameter R1 is, for example, to measured value D1 The formula that difference between measured value D0 is calculated, and be also, for example, the ratio to measured value D1 relative to measured value D0 The formula calculated.In step (Va), parameter R1 and predetermined a reference value RS can be contrasted and judge that waterproof is saturating Whether gas (entrant sound) film is qualified.The judgement for example carries out in the following manner：Water pressure resistance (D1) after cleaning is relative to cleaning When the ratio R 1 (D1/D0 × 100) of preceding water pressure resistance (D0) is become more than predetermined ratio RS, waterproof and breathable (entrant sound) film is judged Qualification, when ratio R 1 is less than ratio RS, judges that waterproof and breathable (entrant sound) film is unqualified.The ratio RS related with water pressure resistance is for example For 50%, preferably 70%, more preferably 80%, particularly preferably 90%.In addition, represented using Ge Erlai numbers In the case of manner, gas permeability is better, and numerical value is smaller, therefore the ratio RS can (unit is " second " using Ge Erlai numbers；It is accurate and Say for " second/100mL ") inverse on the basis of set (for specific numerical value, can also be as the number illustrated in water pressure resistance Value is set like that).

But in step (Va) or, do not calculate parameter R1, using measured value D1 come directly judge waterproof Whether ventilative (entrant sound) film is qualified.In this case, measured value D1 and predetermined a reference value DS are contrasted, and according to for example Whether measured value D1 is predetermined more than a reference value DS to judge whether waterproof and breathable (entrant sound) film is qualified.It is related with water pressure resistance A reference value DS is, for example, 50kPa, is, for example, also in addition 150kPa, and then be 200kPa.

In step (Va), it can also at the same time use using the parameter R1 judgements carried out and directly be carried out using measured value D1 Judgement.Alternatively, it is also possible to be, qualification is defined whether as described above respectively for multiple characteristics, based on its result come final Judge whether qualification.For example, it can be measure the water pressure resistance and air permeability of waterproof ventilated membrane, finally, only by water pressure resistance and thoroughly The film that manner both of which is judged as qualification regards as qualification.

Step (IVa) and step (Va) can also be implemented based on micro- sem observation.In this case, in step (IVa) In, confirm whether surfactant separates out using microscope to observe waterproof and breathable (entrant sound) film, based in step (Va) Whether confirm separating out for surfactant and judge whether waterproof and breathable (entrant sound) film is qualified.Specifically, table is being confirmed When face activating agent separates out, in general, only can be just judged as with this unqualified.In the feelings unconfirmed separated out to surfactant Under condition, both qualification only can be judged as with this, additionally it is possible in the result with further reference to evaluating characteristics as described above On the basis of judge whether qualification.

As long as microscopical species is suitable for confirming the precipitation of surfactant, it is not particularly limited, using sharp Electron microscope, the atomic force microscope such as the light microscopes such as optical scanning microscope, scanning electron microscope (SEM) etc. scan Type probe microscope is preferable.In the case of using such as SEM, seen using amplification factor set in advance (such as 3000 times) The surface of waterproof and breathable (entrant sound) film is examined, can be by being confirmed whether to observe predefined size (such as maximum length is 1.0 μm) More than precipitate implement to judge.

(inspection method of waterproof and breathable (entrant sound) component)

For waterproof and breathable (entrant sound) component, pass through implementation steps successively (Ib), step (IIb), step (IIIb), step (IVb) and step (Vb), it can check whether and be suitable for applying above-mentioned cleaning method.

In step (Ib), waterproof and breathable (entrant sound) structure is used except the fixing member additionally prepared is not used Outside the fixing member that part 68 possesses, test body is made in the same manner as step (Ia) (with reference to Fig. 6).

Afterwards the step of (IIb)~step (Vb) can also be implemented in the same manner as step (IIa)~step (Va).

(manufacture method of waterproof and breathable (entrant sound) film and waterproof and breathable (entrant sound) component)

Inspection method described above can also be as the system of waterproof and breathable (entrant sound) film and waterproof and breathable (entrant sound) component The checking step in method is made to use.Back and forth, for obtained waterproof and breathable (entrant sound) film and waterproof and breathable (entrant sound) For component, by predetermined checking step come the characteristic to these components whole or the part selected using predetermined method Checked.But clean the situation of waterproof and breathable (entrant sound) film due to not contemplating using detergent or make because not established The situation for being difficult to set corresponding inspection method is in clean the proper method of waterproof and breathable (entrant sound) film with detergent, Accordingly, with respect to the cleaning carried out using detergent, it is not carried out checking.

Even the waterproof of passed examination manufacturing according to known methods, to water resistance, gas permeability, sound transparency etc. Ventilative (entrant sound) film, it is also necessary to which consideration for example makes surfactant easy because the foreign matter that surfactant easily adheres to is mixed into film Separated out on film.Thus, for cleaning, it would also be desirable to implement to check with copying above-mentioned inspection method, made from confirmation to prevent Water breathes freely (entrant sound) film or whether waterproof and breathable (entrant sound) component is resistant to predetermined cleaning method.

The inspection of waterproof and breathable (entrant sound) film and waterproof and breathable (entrant sound) component can be that these components are all examined Look into, can also be sampling check in appropriate circumstances.In the case where implementing to survey sample, it is also equipped with from obtained multiple anti- Water breathe freely be selected as in (entrant sound) film (or waterproof and breathable (entrant sound) component) check object waterproof and breathable (entrant sound) film it is (or anti- Water is breathed freely (entrant sound) component) film (component) sampling step, for the waterproof and breathable (entrant sound) selected in the sampling step Film (or waterproof and breathable (entrant sound) component), implements the checking step of film (component).Sampling step can be based on such as JIS Known method as Z9015-1 defineds is implemented.In JIS Z9015-1, illustrate according to ISO2859 series bases In the sampling check benchmark of AQL index type sampling inspection plans.

In addition, in addition to the corresponding checking step of cleaning method, waterproof and breathable (entrant sound) film and waterproof and breathable are (thoroughly Sound) manufacture method of component can be implemented according to known each step, and therefore, the description thereof will be omitted herein.
