Abstract

An airborne-bacteria filter arrangement is used with an apparatus that has an internal airflow. The airflow passes through a fibrous filter arrangement that has, on its fibres, a highly toxic bacteria-killing substance which entraps and kills bacteria in the airflow. A charcoal-infused filter removes the toxic substance from the airflow, and further filters can effuse beneficial substances to the airflow. The filter arrangement is sealed from germ intrusion. The filter arrangement is used in hand dryers and other apparatus such that the airflow can be sterilised to the extent of achieving 100% bacteria removal.

Description

Modified sterilising filter arrangement, equipment and method

Technical field

The improvement of the assembly that the present invention relates to use in indoor equipment, this equipment have internal gas flow and are discharged into indoor people's the environment of an activation from this equipment.

One aspect of the present invention relates to especially for the improvement of the air-flow that discharges from this indoor equipment being carried out the filtration device structure of sterilization.

Other preferred aspects of the present invention include and help realize removing this clarification of objective of 100% bacterium from air-flows.

Other aspects of the present invention also relate to the improved equipment that discharges air-flow, special hand dryer, hair dryer, vacuum cleaner, fan, air-conditioning, refrigerator, the tumble dryer of still not relating to uniquely.

Background technology

Bacterium is by the diffusion of gas flow equipment

Known indoor equipment sucks air and then air is discharged to as air-flow in indoor people's the environment of an activation, therefore is the equipment of propagating microorganism, bacterium and virus.As a result, the people is just easier under this environment contacts with the bacterium of spreading everywhere by the air of being discharged by equipment.

For example, prior art comprises a large amount of dried hand equipment, discharges current of warm air and is used for dried hand.Generally suppose that all the use of this dried hand equipment is a health.But the dried hand equipment that unexpectedly, it is found that these prior aries is actually a kind of approach that spreads microorganism.

Reason is that to carry a lot be the bacterium of carrier with the air to the current of warm air itself from the dried hand equipment of these prior aries.This is to suck air because hand dryer carries from the lavatory in the environment of a lot of bacteriums, and discharges air-flow warm, breed bacteria to user's wet hand.

And many people can not be placed on their hand the long enough time under the current of warm air so that dry their hand fully.As a result, user's warm wet environment on hand is well suited for being blown to by hand dryer the rapid breeding of bacterium on hand.

Many miniature organism in the air-flow is not killed by the heating element heater of hand dryer.And, be vegetative ecotopia from the heating installation body of hand dryer.As a result, these live bacterias are directed to the user on hand.In fact, in fact this hot air blower that it is found that prior art has increased by 500% with bacterial number.

Problem less than 100% removal of bacteria

Although the dried hand equipment of this prior art has acceptance widely in such as communal facilitys such as public lavatories, but use these equipment to be resisted in some field, particularly such as medical fields such as hospital and clinics, and in child care center and food service industry.

For example, when the surgeon uses antibacterial liquid or soap to wash one's hands before undergoing surgery, if the surgeon prepares his wet hand of oven dry in the current of warm air of the dried hand equipment of prior art, if surgeon's hand is by bacterium subinfection then to wash one's hands be useless again.

In addition, in the new millennium, virologist and public health official predict that following mortality influenza and other viral world wides are very popular, and employed wording is when can take place, rather than whether this epidemic disease may take place.When this global epidemic disease takes place, can expect in the indoor equipment that discharges air-flow, to remove 100% bacterium.Otherwise this equipment promptly allows to remove for example 90% bacterium particularly in public places, also can become the instrument of the popular mortality virus of diffusion.In other words, at epidemic period, 100% bacterium is removed and will become extremely important.

Prior art comprises and is used for killing bacteria and/or removes the gas flow equipment that degerms from the air-flow of equipment, but in practice, this known product can not removed 100% bacterium from the air-flow of equipment, particularly uses by long-term.

Although the part bacterium in the air-flow can be killed or remove to this prior art, the final goal of 100% removal of bacteria remains matchless.

Therefore, beginning at this specification, compare with the current goal of from air-flow, removing 100% bacterium, declare to kill or remove degerm and its actual performance for example only can realize from air-flow, removing 80% and even the equipment of the prior art of 90% or 95% bacterium between have obviously difference.

Target is to be faced with at the different obstacles that do not need to realize can not address in the prior art of 100% removal of bacteria target for the invention of removing 100% bacterium.

Prior art

In the prior art, attempted making gas flow equipment can produce the current of warm air that killed bacterium.The main development zone in this field concentrates on the use of ultraviolet ray (UV) ray, kills bacterium in the air-flow with attempt.But unexpectedly, it is not good to have proved that the UV ray kills in the task of air-flow bacterium effect in execution.

At first, must remember that even the UV ray is to kill most of bacterium, the fact is that all the other bacteriums in the air-flow still can arrive the user on hand, and the beginning with minute speed breed.

Secondly, some microbiologists think in fact killing bacteria not of UV ray, and only are the sterilization bacteriums, and just UV just stops bacteria breed or breeding.If really be like this, mean that then the current of warm air that discharges from the hand dryer that is equipped with UV still includes the unhygienic composition of live bacteria.

The final degree of health, 100% removal of bacteria just is for the application particular importance of operation or medical aspect.From this respect, by laboratory tests that the inventor carried out show current on the market some be equipped with ultraviolet hand dryer can not kill 100% bacterium in the release air-flow.

Therefore, the adversary implements often to be not inclined to the dried hand equipment that uses prior art in the vital medical applications of strict sterilization standard, particularly at operation this part, and in the wound medical treatment.

Another problem is, through week time, some months even after several years, microorganism can accumulate in device interior.Because air-flow is inhaled into equipment, by the use that continues, a large amount of bacteriums constantly are drawn in the machine.In other words, machine constantly is exposed to bacterium with contacted all inner surfaces of air-flow.After after a while, machine intimate can become bacterial origin.Behind machine switched off, perhaps when it did not generate air-flow, inner bacterium can continue growth and breeding.When the equipment of prior art can not 100% removal of bacteria, then those remaining bacterias still remained in the equipment, so the inner surface of equipment becomes bacterial origin after after a while.

The air-flow that the equipment of other types also is used for discharging by them is on indoor diffusion bacterium.For example, air-conditioning sucks air, or from outdoor or from indoor environment, and then air-flow is discharged to indoor.Like this, if not 100% bacterium that kills or remove in the air-flow of from air-conditioning, discharging, then may be after after a while, the bacterium in the gas of indoor environment will build up.

As another example, vacuum cleaner from the floor or the surface suck bacterium when sucking particle.Although the filtration of vacuum cleaner systems can filter out particle from air-flow, the bacterium particulate is arranged still in air-flow.They are diffused into the indoor environment by the air-flow that discharges from vacuum cleaner.

Can in other gas flow equipments that suck and discharge air-flow, see the same phenomenon of bacterium diffusion.These comprise for example hair dryer, fan and dryer.Under the situation of dryer, the air that carries bacterium is inhaled into from indoor environment, and is directed to clothing.

Even refrigerator suction air, and discharge the condensation chamber that the air that carries bacterium enters refrigerator, food is exposed to bacterium.

One of target of several aspects of the present invention provides one or more features, they separately or its combination can make the equipment that discharges in the environment of an activation that gas flows to the people in leaving the air-flow of filter, realize 100% bacterium decline.

Another target of the present invention is to overcome or improve one or more problem of the prior art, and the modified replacement scheme of prior art perhaps is provided.

The discussion of the prior art in this specification should not be counted as the approval of the state of the conventional, well-known general knowledge of skilled person in this field or replenish.

The target of this embodiment is to kill classes such as whole bacteriums, microorganism, and term bacterium or microorganism refer to notion in general sense, and should not define narrow sense ground to explain it, otherwise can limit the present invention to the harmful microorganism body that kills a certain class according to biology.

The specific embodiment

With reference to the accompanying drawings, Figure 1A shows the dried hand equipment of sterilization of hand dryer 1 form.

Hand dryer 1 sucks to give vent to anger side by side and flows in the environment of an activation of the frequent visiting of people, such as the lavatory, or the washroom in the hospital, just give some instances here.

Hand dryer 1 is suitable for discharging or discharges the air-flow that adds hot-air 200C through sterilization fully to be used for dried hand.In this example embodiment, the working range of hot-air is approximately 55 to 65 degrees centigrade.

Hand dryer 1 has the base portion that comprises main cover 10 and substrate 11 forms.Substrate 11 and can be seen in Fig. 2 A and 2B in Figure 1B and 1C best.

In Figure 1B, cover 10 is installed on the substrate 11 by hinge 12.

The design of hinge 12 makes cover 10 or to remove from substrate 11 disengagings.This can install hand dryer 1 with simple two step processes: at first, substrate 11 is installed to such as on the vertical surface such as wall, and secondly, cover 10 is connected on the hinge of substrate 11.

Substrate 11 is fixed on the wall by screw 13, screw or other suitable mechanism of ammonium fixation.

Figure 1A shows the cover 10 that is positioned at the closed position, and it is the structure when hand dryer 1 is installed in this position.

Figure 1B shows the cover 10 that is positioned at open position.

In gyp embodiment, cover 10 is locked on the substrate 11, and requires private key 16A to come lock 16B is carried out release, shown in Figure 1A and 1B.

Air-flow

Generally speaking, when using hand dryer to come hand to the user to carry out drying, enter or suck in the frame, successively it is heated then and discharge from the air of surrounding environment.The path of this air-flow is symbolically with the arrow 200A among Figure 1A, the arrow 200C among the arrow 200B among Figure 1B and last Figure 1A represents then.Certainly, the actual airflow in the hand dryer 1 is more complicated and chaotic, therefore, for convenience of explanation it is reduced to

arrow

200A, 200B, 200C.

Air heater

In Fig. 4, hand dryer 1 has the heater of heating element heater 300 this forms.Heater 300 is positioned on the opening part of fan housing 400, and shows clearlyer in the independent bottom perspective view of the fan housing 400 of Fig. 4.

Heating element heater 300 comprises and is suitable for the electric wire grid or the metallic plate that carry out electric heating when hand dryer 1 ejection thermal current.

For Figure 1B and 4, heating element heater 300 is positioned at

frame

10 and 11 inside, and is used for heated air stream 200B, so that air is enough warm, with dry user's hand.

Inlet device

Hand dryer 1 has inlet device, and in use air enters

frame

10 and 11 and transfer to heating element heater 300 by it.

In an embodiment, inlet device is counted as zone or passage, and air transfers to heating element heater 300 by it.

In Figure 1B, inlet device comprises a large amount of assemblies and the feature among the embodiment of Figure 1B.At first, inlet device comprises the

second filter assemblies

520A, 520B and 520C, and air enters frame by it.

Inlet device also comprises the porous inside of frame 10 and 11.Air the flow through

second filter assemblies

520A, 520B and 520C enter the inside of the porous inside of

frame

10 and 11 then.

Inlet device also comprises main-inlet 405, is positioned at the side of fan housing 400.In this main-inlet 405, inserted the filtration device structure (and below tell about other embodiment) of the bacterium that the primary air of

main filter assemblies

410A, 410B and this form of 410C propagates.

The decomposition view of first embodiment of

main filter assemblies

410A, 410B and 410C as shown in Figure 3.

Fig. 4 shows the embodiment of main filter assemblies, and it is engaged in the main-inlet 405 of fan housing 400.

In Fig. 4, under the preferable case, main filter assemblies comprises base element 410A, and it directly is engaged in main-inlet or the main aperture 405.In Fig. 7 B, base element 410A has several elastic hooks 408, is used to make base element and main aperture 405 engagements and pinning.

Fig. 3 shows the decomposition view of the parts of

main filter assemblies

410A, 410B and 410C.

In Fig. 3 and 4, the bacterium of filter material 410B form catches filter for installation and is connected to filter mounting 410C.Filter mounting 410C can mesh with base element 410.

Filter material 410B has the slit, is used for filter is contained in filter mounting 410C.In use, see the most clearly as can see from Figure 4 and in Fig. 7 B, the protruding bolt 411 on the filter mounting 410C passes the slit in the filter.

Each of filter mounting 410A and 410C all has scalping 414, and this has also limited moving of filter material 410B.

Base element 410A and filter mounting 410C have corresponding bayonet socket installing component, are used to make these parts to be combined together in the mode of bayonet type engagement.In other embodiments, can use the mesh mechanism of other forms or style, for example interior dress bolt perhaps is press-fitted and installs or press the lock installation.

Outlet device

Hand dryer 1 has outlet device, and air sprays as thermal current 200C by it after being heated element 300 heating, is used to dry hand.

In an embodiment, outlet device is counted as air and leaves heating element heater 300 up to discharging zone or the passage that is passed through from hand dryer 1.

In Figure 1A, heating element heater 300 is positioned at the inside of the outstanding horn shape opening 14 of cover 10 fronts.Therefore, in example embodiment, pass the distance of inlet device institute warp with air and compare, outlet device is very short on whole distance.

The hot-air of heating element heater 300 of flowing through almost just leaves frame after passing opening 14.

Opening 14 has grid, is used to prevent that user's finger from contacting the heater block of heating element heater 300.

Fan

As can be seen from Figure 4, air-

flow

200A, 200B and the 200C by hand dryer 1 creates by the air-flow generating apparatus of rotary fan 401 this forms.The form of fan 401 is the blade in fan housing 400 inner rotations.In Fig. 4, can see the inside of ring-type fan 401.Usually, ring-type fan housing 400 holds ring-type fan 401.See that in Figure 1B the rotation of fan 401 is by motor 430 operations.In this example, motor is 125 watts, the general-purpose motor of 7500rpm.The outer cover of motor 430 is sealed, enters the air-flow in the fan housing 400 via any slot in the outer cover of motor 430 to prevent bacterium.

The rotary fan 401 that is arranged in fan housing 400 is applicable to the air of fast moving as air-flow.Air-flow enters frame via initial second hole 520D and its

secondary filter assembly

520A, 520B and 520C, then pass the porous inside of

frame

10 and 11, then pass main aperture 405 and pass

main filter assemblies

410A, 410B and 410C, arrive heating element heater 300 up to air-flow.Then, air-flow or the air stream that produces by fan 401 is discharged from frame as the thermal current 200C that can be used in the hand of drying the user.

The position of main filtration device structure

The inlet device of hand dryer 1 comprises " main-inlet " of at least one main aperture 405 form.This main aperture is counted as unique inlet that air and bacterium enter fan housing 400.

The notion of " main-inlet " is that all air-flows from the hand dryer ejection must pass main-inlet at last for the first time.In an embodiment, if all air in the air-flow that comes out from hand dryer must pass completely through hole or inlet at certain on a bit, then opening is defined as " main aperture " or " main-inlet ".

Place on described one or more main-inlet by effective bacterium being caught filter, can guarantee that all air-flows that come out are all caught filter by bacterium and intercept and capture from hand dryer.

In an embodiment, main aperture 405 is positioned on the fan housing 400.Main aperture 405 is the openings in the fan housing 400, must pass this last filter 410B so that enter all air of fan housing 400.After air-flow enters fan housing, only there is an outlet 14 of equipment 1.Therefore, so this main aperture 405 is counted as " main-inlet ", because do not enter the inlet of fan housing except this has other.In other words, there are not other paths of leading to last outlet 14.

Below explanation can allow the definition of " main-inlet " easier, for example, owing to exist many other paths to allow air enter this equipment, so the inlet of the secondary among Figure 1A 520D can not be counted as " main-inlet ".For example, when cover 10 was opened, bacterium can be walked around secondary filter 520D, perhaps when cover 10 is closed, and bacterium even can enter by the slot in cover 10 and the substrate 11.For example, when cover 10 was opened, the indoor gas that carries disease germs in the toilet poured in the inside of this equipment 1.In addition, at inlet 520D and exporting at last between 14, have a large amount of inner surfaces in the inside of equipment 1, it can be infected after having used several months or several years and becomes the source of bacterium.Secondary filter 520B can not intercept and capture the extra bacterium that enters air-flow by such as other channels such as the cover of opening or inner surfaces, but last main filter 410B can block this extra bacterium.Here it is why secondary inlet 520D be not regarded as " main-inlet " and why secondary filter 520B be not regarded as the reason of " main filter ".

In Fig. 4, can see the main-inlet of main aperture 405 forms.In the explanation of Figure 1B, this main aperture 405 is blocked, and this is because shown

main filter assemblies

410A, 410B and 410C has been inserted in the main aperture 405 in the fan housing.

This

main filter assemblies

410A, 410B and 410C blocked air-flow before air-flow arrives heating element heater 300.Main aperture 405 for the air-flow in all hand dryers if from hand dryer, discharge the point that must pass.Here, bacteria particles is caught at last, and therefore intercepting it enters fan housing 400.Under the preferable case, outer cover 400 and other parts of 430 are sealed, so that air can not for example enter by motor outer cover 430.

By

main filter assemblies

410A, 410B and 410C are placed on the last point that enters fan housing, it is as last possible defence line.This guarantee the bacterium that might rest in the air-flow intercept by main filter 410B.Even bacterium is unexpectedly by the slot in the wall of equipment or because the long-term bacterial buildup of device interior enters machine, this bacterium can not be discharged by exhaust jet stream 200C from grid 15, and this is because any air-flow that leaves equipment all must pass main

filtration device structure

410A, 410B and 410C at last.

Therefore, the identification of the position of the main filtration device structure at last inlet point 405 places of main-inlet and fan frame is that a kind of equipment that helps is in the feature that realizes 100% removal of bacteria and elimination from the air-flow 200C of drying equipment 1 ejection.

We know, in the prior art, also are potential this problems of bacterial origin if do not consider to solve the inner surface of device interior, will realize that then 100% removal of bacteria is very difficult.Each inner surface of device interior and parts all are potential pollution sources.For example, the surface of interior lacquering can emit toxin, and air-flow also may cause the internal part fragment that comes off after using the several years.In the prior art, the filter that is positioned at the very forward place of air flow path can not stop the bacterium that comes out from the inner surface in the downstream of filter.

Therefore, in the present embodiment, main filter 410B last under the preferable case is located immediately on the fan frame, so as all these be in the extra pollutant and the bacterium of air-flow upstream can be by last intercept and block before entering the fan frame with main

filtration device structure

410A, 410B and 410C.Before air-flow arrived the heating element heater 300 and the port of export 15, main filtration device structure was positioned on the last possible position.(filter is placed the inside inconvenience of fan frame, and this is because filter is not easy to be replaced, and the filter that is not easy to be replaced self may become pollution sources after using a period of time)

In the present embodiment, main aperture 405 and relevant main

filtration device structure

410A, 410B and the 410C inside that all is positioned at equipment rack 10 and 11.This has guaranteed that the user can not contact main filter assemblies, and only to allow professional authorized person to contact and change.

In other are revised, existence is positioned on the fan housing 400 more than one or more main aperture 405, but in this modification embodiment, all air that still need to enter fan housing 400 must pass these and be positioned at one or more main apertures 405 on the fan housing.

In the present embodiment, even bacterium will enter by the slot in

frame

10 and 11, the position of main filter 410B on the fan housing just enters unique inlet of fan housing, has guaranteed that this main filter 410B can block the bacterium that all enter fan housing 400.

In the embodiment of Figure 1A and 1B, main-inlet 405 is arranged in the inlet that leads to the air-flow generating apparatus, perhaps in other embodiments, if all air that enter the air-flow generating apparatus all pass this final approach, then can change its physical location.

In an embodiment, main aperture (or a plurality of main aperture) only is positioned at or is connected to fan housing 400, so that all air-flows that enter fan housing all must pass this main aperture.This is preferred and optimum position, shown among the embodiment of Figure 1A.

Another Consideration of design present embodiment is as can not conducting interviews from the outside of hand dryer 1 under the main aperture preferable case of main and unique opening that enters fan housing 400.For example, the main aperture 405 that enters fan housing 400 can not conduct interviews from the outer surface of cover 10, otherwise just can allow unwarranted user visit the moving-member and the parts that are connected with electric wire of dried hand equipment 1.This also in the motor-driven parts of equipment, be inserted with harmful substances for the saboteur in addition in fan and motor water filling chance is provided.All these possibilities all may endanger the user of hand dryer 1.

Bacterium catches

Bacterium is actually by atomic little microscopic particles to be formed.The hand dryer 1 of present embodiment has bacterium and catches filter for installation.In other words, this device is used to catch bacteria particles, so that in fact the air of ejection is not with bacteria particles from hand dryer 1.Emphasis not only is killing bacteria, also is to catch bacteria particles.

In the present embodiment, in Fig. 3, the bacterium of

main filter assemblies

410A, 410B and 410C catches filter for installation and comprises filter material 410B, it is fiber quality, fine and close, common uneven filter material matrix, it is enough fine and close, can block and catch the bacteria particles of the overwhelming majority in the air-flow.These fibers are as stopping the physical obstacle that bacteria particles is passed through.

In the present embodiment, find in routine is used, for example in common communal bathroom facility,, therefore will just change filter material 410B every other month in the ideal case owing in filter material, can accumulate bacteria particles.

Filter material

In exemplary preferred embodiment, filter material is the non-woven fiber material that mixes.Owing to find that its weave of textile material is closeer, compare easier restriction air-flow with non-woven fiber material, thereby be not suitable for, so adopt non-woven fibre under the preferable case.

Filter material among the embodiment of Figure 1A is nonwoven, pin felt, polyester fiber packing material, and it has following feature:

Weight (gsm)	150	ISO?9073-1：1989
Weight (gsm)	150	ISO?9073-1：1989	Thickness (mm)	1.4m～1.8mm	ISO?9073-2：1995
Tensile strength (N/50mm):--vertically--horizontal	165 165	ISO?9073-3：1989	Thickness (mm)	1.4m～1.8mm	ISO?9073-2：1995

Air permeability (1/sec/m ²)

2,500

IS?O9230＠20cm ²/200Pa

In another preferred sample of filter material, air permeability is determined according to Australian Standard AS2001.2.34-90.The result is that the air permeability that the preferred sample of filter material has is 234.7cm3/cm2/sec, and the coefficient of variation is 5.9.

The polyester fiber matrix of filter material for mixing, it has the weaving matrix of completely random or with method of weaving.Therefore, the bacteria particles of passing in the air-flow of this fibrous matrix must be passed tortuous air flow path through at random fibrous matrix the time, therefore increased the possibility that each bacteria particles strikes one of fiber or caught by fiber.

Usually, adopting fine and close filter to owe fine and close filter to guarantee selecting to exist compromise between these two conflicting requirements of air-flow faster to help bacterium to catch still to adopt.

Problem is: bacteria particles has more effectively been caught in the density of filter or the increase of thickness on the one hand, but has also reduced the air-flow by filter simultaneously, and this can cause that fan motor is overheated.Therefore, if want to realize the selected objective target of 100% bacterium blocking-up, then need to carry out the appropriate density that some test the filter material that finds the motor that is applicable to the certain power among the given embodiment and fan.For example, produce the more powerful fan of air blast, can adopt the bigger or thicker filter material of density by employing.

The screen pack weight of calculating with gsm (every square metre gram number) can demonstrate the character of average-size of the slot of screen pack.

For example, we find that the fibrous matrix of 50gsm caught bacteria particles fully, but the fibrous material of 50gsm can not provide sufficient air-flow for fan 401.

In the prior art, exist by selecting very meticulous screen pack to realize the trend that bacterium is filtered.Theory of the prior art is similar to the idea of the fishing net that is used to fish, and wherein the size of mesh must be fully little, is complementary with the size with bacterium.This can cause the decline owing to mesh size, the problem that the ability that air-flow passes through at a high speed also descends thereupon.Owing to do not recognize and the very meticulous relevant problem of filter mesh size, in the prior art of the very meticulous sterilizing filter of known employing, be not easy to find this problem.

Present embodiment has been recognized the problem of conflicting needs.On the one hand, need the filter mesh to be enough to catch bacteria particles, but on the other hand, mesh again can not be too little so that hinder best air-flow.

In the present embodiment, mesh size is chosen as about 150 microns weaves, that is to say that average slot or the hole between the fiber of non-woven material is approximately 150 microns.This is from realizing that between this size field quick air-flow can guarantee again to select the large-scale filter material of 100% bacterium capture ability simultaneously.Use because filter is the viscous liquid coating on being positioned at filter, make and use 150 microns relatively large weaves of this hole dimension to become possibility, as described below.

Under the situation of bound by theory not, can suppose in the prior art that it is because the mean size greater than bacteria particles is wanted significantly in the hole of 150 microns weaves that 150 microns weaves are not considered to be used for suitable width of mesh that bacterium catches.But, in the present embodiment, we think when fiber is coated with the toughness antibacterial liquid, near the mesh size that is chosen in 150 microns is suitable, this is because bigger hole allows quick air-flow, and can present the random airflow path of enough complications simultaneously, this can guarantee that 100% bacterium can impinge upon that one of fiber is gone up and can be owing to viscous coating sticks on it.

Therefore, select about 150 microns weave to use different mechanism to catch bacterium.Bacterium not necessarily only is to catch (fishing net that is similar to fishing) between the slot of two adjacent fibers.But we find that the weave of 150 microns fibrous matrix provides enough winding raods footpath, and this makes that the probability of bacterium and fiber collision or collision is high.In addition, as described below, fibre bundle scribbles cohesive material, more likely be attached on the fiber to guarantee the bacteria particles that bumps against with filter fiber, rather than along with air-flow advances.In other words, in 150 microns filter mesh, the big slot in the fiber can make air-flow pass filter material fast.Simultaneously, 150 microns fibre density has guaranteed that along with air passes filter, airborne bacterium is filtered the device fiber and catches.

In other words, being that the speciality of fibrous material and the viscous coating gang on the fiber solve i) bacterium catches and ii) this a pair of contradiction requirement of air velocity.

Certainly, though the filter about 150 microns is extensive use of on market, adopts the filter mesh about 150 microns to realize i simultaneously) 100% bacterium catches with ii) higher this beyond thought result of air velocity and remains the selection that a kind of past do not predict.Why selecting the mesh about 150 microns is because big hole dimension is the doubly a lot of of common bacteria size unexpectedly.In fact and unexpectedly optimal selection the selection of present embodiment proves, if combine use with viscous coating, seems that then very big filter mesh.

Can carry out some tests, determining acceptable upper and lower bound, the form with the positive and negative deviation at 150 microns places makes and still can realize i) 100% bacterium catches and ii) very high this dual and unexpected target of air velocity.

Main filter 410B catches and holds back the most bacteria particles in the air-flow in filter.It is more aseptic when therefore, the air-flow ratio that leaves main filter 410B enters filter 410B.

In the preceding paragraph, word " is held back " bacterium that refers to the overwhelming majority and has been entered, but can not leave filter.In other words, leave the air-flow of main filter 410B and compare, have quantity bacteria particles still less with the air-flow that enters main filter 410B.

The air-flow that leaves filter 410B that is characterized as of the present embodiment of having verified through independent microbiology test is 100% not to be with bacterium fully, and is perhaps at least almost aseptic and approach 100% target terrifically.In other words, bacteria particles is not only deactivated or kills, but largely by physical property from air-flow get rid of.

The early stage experimental model of present embodiment is to test in the male sex washroom of factory, and wherein checking is to have the air pollution that has different microorganisms.Find at last that from hand dryer 1 air-flow 100% of ejection is not with bacteria particles or pathogen.Therefore, the bacterium of present embodiment catches filter for installation and can 100% ground catches bacterium in the air-flow, therefore leave the air-flow that bacterium catches filter for installation to be, or aseptic near 100% fully.

Therefore obviously, the embodiments of the invention that can realize 100% aseptic dried hand target when dried hand demonstrably even than disposable paper handkerchief health more.For example, can realize that model near 100% removal of bacteria also is applicable to promptly will carry out operating surgeon.

Therefore, of the present invention aspect this in, the embodiment of hand dryer 1 has the device that is used to catch and hold back actual bacteria particles, so that prevent that bacterium from leaving hand dryer and entering among the thermal current 200C.This is having employed air cleaner in the hand dryer now in conceptive being different from, existing air cleaner only is to filter out such as bigger particles such as the dust and the grains of sand, and is not suitable for even does not expect and will catch bacterium with the standard of 100% removal bacteria particles.Therefore, only told about " air cleaner " unless any prior art told about the actual acquisition of bacteria particles, then its initial target just can not must be regarded as bacterium is caught the formerly open of filter for installation.

The broad sense prerequisite of present embodiment is for effective killing bacteria, must catch bacteria particles.This method with existing sterilization hand dryer is different, and these sterilization hand dryers are attempted at first not caught and hold back bacteria particles on bacterium by killing bacteria in the air-flow of the fast moving transmission.In experiment, we find, the EXPERIMENTAL EXAMPLE of the present embodiment that kills with the bacterium that is hunted down that at first catches bacterium and then can not move in filter is compared, and this existing technical system is very different in the validity of removing the bacterium this respect from air-flow.

In a word, fibrous matrix can be caught to physical property bacteria particles, and also air-flow is presented minimum obstruction simultaneously.Therefore, remarkable size greater than bacterium is wanted in average slot between the fiber or hole, to hinder air-flow as small as possible.In addition, fibrous matrix is that air-flow has been created the winding raod footpath, impinges upon at least some fibers of fibrous matrix so that bacteria particles has high possibility.

The example of filter material

As an example, employed in the present embodiment filter material is a combing spunbond polyester film, has the multiple with organic fiber of every square meter 150 grams.The measurement thickness of filter material is 1.4～1.8mm.In the 150gsm filter material, this is 25001/sec/m than the maximum air velocity permeability that macropore allows ²

In drying regime, it is about 30～40 microns fibre matting that this material provides average slot or hole.Therefore, in drying regime, this material will realize that it is inadequate that 100% bacterium catches, and this is because bacteria particles is generally 0.3～30 micron, and virus is between 0.01～0.05 micron.Therefore, in its drying regime, 150gsm filter material self can not realize 100% or near the target of 100% capture rate.But, when the viscous coating on the binding fiber, select this obviously too big mesh size but can realize the target of 100% capture rate unexpectedly, can also make air-flow simultaneously fast by bigger hole.

Compare with the capture rate of the normal, expected that only adopts 150 microns hole dimensions to extrapolate, the viscosity of newly-increased coated fiber makes the ability of catching particle strengthen manyfold.

Fungicidal substance: the bacterium in the filter is killed

In a preferred embodiment, filter material 410B scribbles the Fungicidal substance that can kill the bacterium that wherein is hunted down and holds back.

Fibrous matrix has poisonous Fungicidal substance on its fiber, it can kill any bacterium on any Fungicidal substance that impinges upon on the fiber.

Therefore, on the fiber of filter, also killed the bacterium of the overwhelming majority that in filter, is hunted down and holds back.If (in filter, do not have anti-biotic material, then catch bacteria particles and can cause bacterial infection in the filter material)

The advantage of present embodiment is to catch germ or bacterium, when they are in the filter it is killed then.Otherwise, it is not killed iff catching bacterium, then the bacteria levels in the filter can increase gradually along with the time.Then, when machine switched off or shut-down operation, the bacterium on the filter can grow, so filter self can become bacterial origin, makes bacterium spread to entire equipment, thereby infects inner surface.

When the anti-biotic material that is used for killing bacteria kills the role of the bacterium that filter catches in execution, can be liquid or gel.

In fact in the present embodiment, Fungicidal substance is directed onto on the fiber filter modulator material with the form of alcohol-based liquid spraying.When alcohol vapored away, Fungicidal substance rested on the fiber random matrix.

In the present embodiment, Fungicidal substance is that liquid is executed material.When Fungicidal substance was applied on the fiber as liquid, it formed viscous coating on fiber, was used to help to catch the bacterium on the Fungicidal substance that impinges upon on the fiber.Viscous coating can physically remain to the bump bacteria particles on the fiber, so that bacterium is fixed on this position and kills.

What deserves to be mentioned is that the anti-biotic material of any kind of or liquid may be used to kill the bacteria particles of being caught in filter 410B and 520B.In the present embodiment, this material is by Healthguard Corporation of Campbellfield, and Victoria, Australia make, and production number is AFA-BK, 9-260.

In the present embodiment, because the antibiotic cohesive material on the filter may not keep its validity after a period of time, catch filter 410B and should change in every month.

Another modification: filtration device structure

In first embodiment of Fig. 4, in main filter assemblies, there is a main filter 410B.In this first embodiment, though anti-biotic material has killed the bacterium that impinges upon on the filter 410B, its defective is that the anti-biotic material of trace can stay in the air-flow, and will leave in the environment that filter enters the mankind's activity environment.Though these micro-anti-biotic materials unlikely threaten the general population, for some particularly suffer from the people of breathing problem or tuberculosis, but be highly dangerous.For example, the people who suffers from the cystic fibrosis disease may be subjected in the atmosphere even the harm of the toxic material of trace.

Anti-biotic material can kill 100% usually the most during the level of the bacterium of severe toxicity when being in, and also is poisonous and harmful to the people usually.For example, might stimulate eyes.

For killing bacteria, Fungicidal substance requires to have very high toxicity, but this toxin need be got rid of from air-flow under the preferable case.

In order to remove the toxic material of any trace from air-flow, Fig. 7 A and 7B show the principal fiber filter 410B with poisonous Fungicidal substance and have active carbon or carbon filter device successively.That in the present embodiment, the activated carbon filtration apparatus adopts is notes NACF or the porous filtering modulator material 410D that is marked with active carbon or carbon granule.

In annotating activated carbon filtration modulator material 410D, active carbon or carbon granule block or remove any poisonous Fungicidal substance that derives from the coating of catching on the filter 410B from air-flow.This has guaranteed that the air-flow that leaves main filter assemblies does not almost not only contain bacteria particles, nor contains the Fungicidal substance of trace.

As mentioned above, from air-flow, remove Fungicidal substance and make that equipment 1 can be with in the mankind's activity environment that has the responsive crowd of lung therein, for example hospital.

In addition, owing to from air-flow, removed Fungicidal substance, so this allows to use Fungicidal substance more efficiently on the first fabric filter 410B.This is because if there is not subsequently active carbon filter 410D, may the personnel in the surrounding environment be worked the mischief owing to worry the severe toxicity in the air-flow, therefore need limit the use highly toxic material in the first filter 410B.And when adopting subsequently active carbon filter 410D, use the higher material of toxicity can make equipment in its sterilizing ability, realize bigger validity at the first filter 410B.In the present embodiment, because of existing active carbon filter can use the higher material of toxicity to help to realize that the air-flow 100% from equipment 1 ejection is aseptic.

And then, under the situation of bound by theory not, can believe that active carbon carries out oxidation again to air-flow when airflow passes is annotated active carbon filter 410D.

Therefore, active carbon has double action, at first removes poisonous antimicrobial chemical material, secondly air-flow is reoxidized.Active carbon also can be removed foul smell and smell from air-flow.

In the present embodiment, fiber filter modulator material 410D has been injected into activated carbon granule or powder, but revises among the embodiment at other, if loose structure does not hinder air velocity basically, then also can use the more active carbon of pore or annotate absorbent charcoal material.

In the present embodiment, active carbon filter 410D master catches and killing bacteria if it were not for being used for.Catch among the filter 410B first and to carry out the step that is used to catch with killing bacteria.Therefore, should arrive 100% aseptic level, perhaps enter active carbon filter 410D place and be close to this level that is at least at air-flow from the air-flow of catching filter 410B.

In fact, active carbon or carbon catch and killing bacteria aspect do not have advantage.Under the situation of bound by theory not, active carbon is not a kind of suitable substrate that is used to place Fungicidal substance, and this may be because Fungicidal substance is adsorbed to the inside of activated carbon granule, but not allows Fungicidal substance stop from the teeth outwards to be used for killing bacteria.In addition, suppose that it is liquid or to have applied the Fungicidal substance of liquid in the present embodiment that activated carbon granule may pollute.In a word, the active carbon filter 410D in the present embodiment and be not suitable for the step of carrying out killing bacteria.

Because active carbon filter 410D does not comprise viscosity antibacterial liquid coating in the present embodiment, therefore before arriving active carbon filter 410D, air-flow just should realize that 100% removes bacterium from air-flow.If no, mean that then some bacteriums may arrive active carbon filter, and this bacterium when not working, air-flow may breed.This can cause after a period of time, and active carbon filter is transformed into bacterial origin.Therefore, before air-flow arrives active carbon filter, must remove bacterium in 100% ground.

Filter frame-bacterium can not enter

(be similar to the situation of Fig. 4) in second embodiment of Fig. 7 A, the base element 410A of filter assemblies is suitable for being directly installed in the main-inlet or main aperture 405 of fan housing.

In the decomposition view of Fig. 7 A, the first filter mounting 410C is installed on the base element 410A, and the second filter mounting 410E is installed on the first filter mounting 410C thereupon.

Fig. 7 B shows and is in the assembly of assembled state among Fig. 7 A.Assembled part is installed together with the bayonet type engagement, but also can adopt other forms of connection mechanism in other embodiments.

In Fig. 7 B, arrow 409 shows the direction of air-flow when use equipment 1.In Fig. 7 B, filtration device structure has the filter barrier device, and this device comprises the wall of filter mounting in an embodiment, when filter mounting is assembled, installs very closely.It also comprises the barrier of being created by the interface of base element 410A lower limb and fan frame.

The wall of filter mounting 410C and 410E is when being incorporated into when using together, as holding main catch filter 410B and active carbon filter 410D.The net effect of filter barrier device is to provide bacterium impermeable barrier for filter 410B and 410D.The impermeable barrier of this effective bacterium separates

filter

410B and 410E with the inside of equipment.This means when air-flow is blown over equipment 1, even that when air-flow is not blown over the bacterium of device interior or other pollutants can only enter filtration device structure via the face of the main filter 410B of the air-flow of directly facing into.Pollutant and bacterium can not pass the miscellaneous part or the junction of filtration device structure.

In the embodiment of Figure 1A to Fig. 4,

filtration device structure

410A, 410B, 410C, 410D and the 410E of airborne bacterium is positioned at the inside of equipment 1 fully.

When base element 410A and

filter frame

410C and 410E are installed together, because by the impermeable barrier of the bacterium that close installation produced of assembly, bacterium can not enter the inside of filtration device structure by the abutment of

assembly

410A, 410C and 410E.This is a kind of advantage, because the same with any machine, the inner surface of equipment 1 all is potential pollution sources, is from the used material of manufacture component no matter pollute, although come from the bacterium that wherein exists protection still to enter machine.Therefore, bacterium impermeable barrier has prevented bacterium (side or the binding site of 410A～410E) has entered by filter assemblies.

In addition, the impermeable barrier of identical bacterium has prevented when closing device or when not producing air-flow, any viable bacteria of filtration device structure inside escapes the inside into this equipment.For example, in Figure 1A, bacterium may enter by grid 15.For example, when not using this equipment, the impermeable barrier of bacterium prevents bacterium access arrangement inside.This has been avoided device interior itself finally to become bacterial origin.(when closing machine, main filter 410B prevents that bacterium that the passage 14 via relative tail end enters from arriving the interior zone of equipment.In case open once more and use equipment, any bacterium of tail end passage 14 all can be killed by the heat from heating element heater 300)

Creating the impermeable barrier of bacterium in the surface of filtration device structure has replenished and has been used for separately and/or the function of other features of these equipment that prevent bacterium access arrangement inside as much as possible of combining.This has been avoided or has reduced the situation that the inside self of drying equipment 1 wherein may become bacterial origin to greatest extent.

These features that reduce bacterium access arrangement inside to greatest extent help equipment 1 to realize that successfully 100% gets rid of bacterium from air-flow.Even when this equipment does not produce air-flow, prevent that bacterium from entering inside also is to influence another factor whether entire equipment can realize 100% removal of bacteria target in other words.

As mentioned above, main in the present embodiment filtration device structure 410A～410E is positioned at the final approach place of fan frame 400.In conjunction with this fact,, main filtration device structure only guaranteed further that except by the front portion of main filter 410B, bacterium can not pass main aperture 405 by slot in the filter assemblies or binding site for providing the impermeable barrier of bacterium.

In other revise embodiment, can be designed for the mechanism that the parts with filter assemblies are installed together, so that in case after installing, these assemblies can not be unpluged by the user.Can provide-locking mechanism of a little forms.This has guaranteed that the user can by mistake not open filter assemblies, thereby discharges bacterium wherein.For this embodiment of the present invention, whole filter assemblies 410A～410E needs whole periodic replacement.In the present embodiment, the suggestion filter assemblies was changed once at least in every month.

Note, in some cases, particularly in non-medical environment, can not be strict with the use active carbon filter.The crowd who is in common health status can stand the Fungicidal substance that contains trace in the air-flow in spraying to ambient atmosphere.

Integrated unit: change and abandon filter and assembly thereof

By Fig. 3,7A, 7B, 8A, 8B and 1B, filtration device structure is in the form of complete individual unit after assembling.In other words, all associated components of filtration device structure all are comprised in the replaceable and discardable unit.When main filter 410B began to be full of the bacteria particles of catching and killing, whole main filtration device structure can be used as an integral body and removes and change.This is a kind of advantage, when filter begin by the bacteria particles of catching and killing when blocking, can be easily more the change owner filter assemblies guaranteed that himself can not become bacterial origin.Not only the fabric filter material require is changed, and can also be needed by its peripheral components that bacterium infected to change.The equipment that is installed in dispersedly in the machine as the prior art of separation assembly at assembly does not have this advantage.

Integrated unit: the inner surface of replacing and drop device

The ability of removing and change individual unit also has another advantage.It not only can change

filter cell

410B and 410D, and it is also important that, it can also remove and change " inner surface " 412 of the equipment 1 at the most approaching metapore 405 final approach places.This has guaranteed that these inner surfaces 412 itself can not covered by bacterium or other pollutants after having used several months or several years.

This has proved that the design of equipment must consider that assessment used the potential performance after the several years, and is not only the function when it is very new.After several years, the inner surface of machine may also be polluted by bacterium.This realizes 100% difficulty of removing bacterium from air-flow for the equipment that can use the several years after long-term the use increased another factor.

Therefore, the inner surface that can change the equipment of the most approaching metapore 405 is to help to realize 100% removal of bacteria in the present embodiment, is not only in new equipment and after using the several years, another factor.

In prior art equipment, can remove though spread all over the assembly of equipment, be difficult to change inner surface.Therefore, in the present embodiment, the sealed environment of creating in the main filtration device structure can be used as that single unit is removed and replacing is an advantage.Important inner surface towards metapore can be changed at an easy rate.This has guaranteed after a period of time, can not become bacterial origin as the inner surface in the downstream of catching filter 410B at last itself.

In Fig. 7 B, 8B, 9A and 9B, the main filter 410B that catches is separated by the capacity region with capacity slot 413 this forms with notes active carbon filter 410D.Slot 413 is sealed within the impermeable barrier of bacterium.Capacity slot 413 is caught the interim destination that is entered after the filter 410B as air-flow leaving.Under the situation of bound by theory not, the capacity slot 413 of this qualification helps air-flow is remained within the localized area, rather than a large amount of diffusion, and this can increase the air sinuous flow and reduce air velocity.

When not having air-flow to pass, main catch filter 410B and annotate that active carbon filter 410D normally is parallel to each other, so that capacity region is flat with tabular therebetween.

Air-flow leaves the master and catches filter 410B and enter notes active carbon filter 410D, and its mode is that air-flow is vertical substantially with the surface of each filter for installation.

In Fig. 7 A, the brim height of each filter assemblies has been determined the distance of the slot 413 between each filter assemblies.We know, the distance between the filter assemblies can influence the flow through ability of whole filtration device structure of air.Reason is that

identical filter material

410B and 410D is placed to together, and as the heavy parting of single filter material and clearance seam not, this can not realize the identical speed of air-flow.

Active carbon filter 410D should be relatively near catching filter, so that can block the antibiotic toxic materials that all come autonomous filter 410B basically.Otherwise, if active carbon filter 410D with catch filter 410B and separate very big distance, then after the several years, can see that toxicity antimicrobial chemical material stably is deposited on the inner surface on the inner surface in main equipment of catching between filter 410B and the notes active carbon filter 410D.Therefore, slot 413 is the smaller the better.Little slot 413 has been guaranteed almost to enter active carbon filter 410D immediately from the air-flow that main filter 410B comes out, and this probability that makes the toxicity antibacterial liquid be deposited on the inner surface of equipment is less.

Injecting substances

Brief review once, air-flow enters filtration device structure via catching filter 410B, in catching filter 410B, the antibacterial liquid that bacterium is painted on the fiber is caught and is killed.Next, successively, the air-flow that comes out from filter 410B enters notes active carbon filter 410D, and any micro-antibacterial liquid in the air-flow is removed herein.

Among the 3rd embodiment of Fig. 8 A and 8B, follow two

filter

410B and 410D closely, in the 3rd frame 410G, can also accommodate the release filter for installation of this form of spray filter 410F.

The purpose of this spray filter 410F is to increase in air-flow or inject some the useful property released materials.For example, but useful injecting substances can be the medicine that can take to the user in the mode that air is carried secretly.In an example, medicine can be by the employed medical substance of the people that suffer from asthma.Usually, the people that suffer from asthma use inhalator, and with the medicinal steam of inspiration, but, embodiments of the invention can be used for this material is injected atmosphere on every side, so that can suck medicine continuously with more small dosage.This method can be used for other disordered breathings, for example bronchitis and nasosinusitis.Potentially, any suck the minor ailment that steam treats by people can be by this surge be taken medicine in air.

Under the optional situation, but useful injecting substances can be a fragrance.The environment that is used for having tedious foul smell when equipment 1 for example during communal bathroom, need be injected into material with fresh air in the atmosphere, and this just becomes of great use.This can be applied to the aromatotherapy field especially.

In medical field or other washrooms under the situation of employed hand dryer, even should get rid of from air-flow under the hypertoxic Fungicidal substance preferable case that main filter 410B comes out, but this spray filter 410F subsequently can spray and catch the extremely toxic substance that filter 410B go up to exist and compare the relative less antibacterial material of toxicity.When user's hand was dried, the less material of this toxicity can be directed onto the user on hand.This just provides extra antibacterial treatment for hand.

In the present embodiment, use the less antibacterial material of toxicity that discharges from spray filter 410F also to carry out extra task, be used to kill or minimize amount of bacteria via tail end opening 14 access arrangements 1.

As described below, each the useful property released material can use in conjunction with chemoreleaser.

The vibration filter

Fig. 9 A and 9B show the embodiment that its middle filtrator is installed in its filter frame inside, and Fig. 9 A is the situation that does not have air-flow, and Fig. 9 B is the out-of-date situation of air communication.

In the present embodiment, aforesaid filter is the form that loosely is mounted to the flat pieces filter material of pin 411.Loose being installed in of filter makes filter to tremble in air-flow on the pin, illustrate as Fig. 9 B.Under the situation of bound by theory not, we know, the vibration of spray filter 410F help the property released material from the fiber jet of filter 410F to air-flow.

Acceptable filter sequence and combination

Various embodiment of the present invention has multiple acceptable filter sequence and/or combination.

In all embodiment of filtration device structure, it is essential that main bacterium is caught filter 410B.

For the specific medical environment, and exist therein even the master of trace is caught in other human environments of an activation of all very sensitive people of employed hypertoxic antibacterial material among the filter 410B, catching under the preferable case after the filter 410B is to annotate activated carbon fiber filter 410D.

People can omit and annotate activated carbon fiber filter 410D unlikely among very sensitive other embodiment of the toxicity Fungicidal substance of trace therein.For example, in this case, spray filter 410F can be in turn after catching filter 410B, as next filter.

In addition, in other environment, can not need spray filter 410F, and it is just enough only to catch filter 410B, adds sometimes in the time of necessary and annotate activated carbon fiber filter 410D.

Filter sequence and combination: four filters

Fig. 8 C and 8D show the 4th embodiment that filtration device structure wherein comprises four

filter

410B, 410D, 410F and 410FF successively.

In Fig. 8 C and 8D, the air-flow by filtration device structure at first runs into mainly catches filter 410B and annotates active carbon filter 410D.Next be exactly two spray filter 410F and 410FF.

In the present embodiment, when having two or more spray filter 410F and 410FF, all comprise a kind of different useful property released under each spray filter preferable case and penetrate material.

For example, the next filter 410F in the sequence can spray fragrance or fragrance in air, can spray the less antibacterial material of toxicity with last filter 410FF in the time series.

Therefore, in four filter embodiment of Fig. 8 C:

I) bacterium in the air-flow is filtered that device is caught and is killed by the hypertoxic antibacterial material on the first filter 410B;

Ii) poisonous antibacterial material is removed from air-flow by annotating active carbon filter 410D;

Iii) fragrance or the fragrance from penult spray filter 410F is evaporated in the air-flow; And

Iv) vaporific appropriate antibacterial material is injected in the air-flow by last spray filter 410F, so that the air-flow that sprays from equipment comprises the non-toxicity antibacterial material of appropriateness.

Notice that be evaporated in the air-flow fully or substantially by material, some materials are injected in the air-flow.By contrast, also having other materials is to be injected in the air-flow as molecule or liquid mist.For example, in example before, fragrance or fragrance are evaporated in the air-flow probably, are the forms that mist enters air-flow and the appropriate antibacterial material of some types is ejected into what adopt probably in the air-flow.

Therefore, when having two or more spray filter 410F and 410FF, and has evaporated material and other have mist when producing material when one in these filters, under the preferable case, air-flow at first runs into the filter 410F that has evaporated material, just runs into then to have the filter 410FF that mist produces material.

If because mist produces material on penult filter (410F among Fig. 8 A), then mist is hunted down probably or is collected on last filter (410FF), enter surrounding environment but not pass, so we recommends this sequence and structure.

Be used to guarantee the filter sequence mechanism of acceptable filter sequence

In order to ensure the assembly in the filtration device structure with expectation series arrangement or be installed together, but each filter mounting all has and is merely able to the mechanism that meshes with predetermined receiving sequence and another filter mounting.Each of filter mounting 410C, 410E and 410G all has can guarantee that filter can only carry out interconnective catenation sequence device with above-mentioned sequence.

But the contour shape of the catenation sequence device on each filter frame all can only accurately mate with the respective profile on the next filter frame in any receiving sequence.In Fig. 7 B, what the catenation sequence device adopted is that bayonet type is installed.The yardstick that bayonet type on each of

frame

410C, 410E and 410G is installed and the design of position have all been guaranteed unacceptable combination not to take place, as mentioned above.

For example, the embodiment of filtration device structure can not make and annotate activated carbon fiber filter 410D as first filter in the sequence.Therefore, in acceptable combination,

filter frame

410C, 410E and 410G are designed to have the connector that can only mate or be connected with another filter frame.

For example, can see acceptable combination in Fig. 7 B, the rear portion of wherein main filter frame 410C can mate and be connected with the front portion of the frame 410D that is used to annotate active carbon filter.

In other embodiments, when having corresponding pin hole, the catenation sequence device adopts is the form of the pin on that filter frame that can only be complementary with another filter frame.The position assurance of pin and pin hole to have only acceptable catenation sequence be feasible.

As mentioned above, when each filter mounting interconnected with acceptable sequence, filter mounting combined and creates the impermeable barrier of bacterium.

Still as mentioned above, filter mounting also is to be installed together with acceptable sequence, to form single lamination.

One or more secondary filter

In the embodiment of Figure 1A and 1B, under

main filter assemblies

410A, 410B and 410C and preferable case, also have 410D～410G, under the preferable case, one or more secondary filter that inlet device also comprises with main filter assemblies 410A～the 410E/G serial links to each other.

In the embodiment of Figure 1A, secondary filter 520B has partly reduced the amount of bacteria in the air-flow, but not all air-flow all passes secondary filter.For example, in an embodiment, when the slot that do not exist between rubber strip sealing cover 10 and the substrate 11, some air-flows can enter in the hand dryer 1 by these slots, and as a result of, allow bacterium to enter by slot.Here it is why in the present embodiment external filter 520B only be regarded as the reason of " secondary filter ".

Keep air-flow

Each of one or more secondary filter 520D all has bacterium and catches filter for installation (520B).Reason is that the filter that has more than has increased the whole combination of filter material " thickness " that bacterium must pass, and is filtered the probability that modulator material is caught thereby increased bacterium.

In the embodiment of Figure 1A and 1B, the air that enters

frame

10 and 11 has finally arrived heating element heater 300 after having passed a series of holes.(because 520D demonstration in this hole has

secondary filter

520A, 520B and 520C in decomposition view, these three parts that show the secondary filter assembly are how to be installed among the 520D of this hole, and therefore initial secondary apertures 520D is blocked in Figure 1A)

The coarse mesh of

secondary filter support

520A and 520C is used to filter out bigger dust and other particles.Other embodiment can comprise more than three layers in the secondary filter assembly.

The secondary filter 520B that is positioned at this initial apertures 520D has stopped the bacteria particles that the overwhelming majority enters the inlet device of hand dryer.But, in fact this secondary filter 520B does not catch all bacteria particles, and also has bacterium can enter hand dryer 1 by the slot in

frame

10 and 11, even when cover 10 is opened.Therefore, being arranged in main filter 410B on the main aperture 405 is used to catch air-flow and escapes from any bacterium that initial secondary filter 520B catches.

According to logic, the thickness of the filter material that air-flow must pass is big more, and then the air-flow captive possibility of bacterium of carrying secretly is big more.But, the thickness that only increases the main filter 410B on the fan inside outer cover 400 is not a feasible solution.This is because the part of the operating parameter that specific air input of the action need of fan 401 or circulation are used as fan.If only thicken main filter 410B, it is lower then can to cause air to enter the speed of fan housing, and this most probable causes fan mechanism overheated and degenerate, even can cause that fan motor catches fire.

Therefore, under the preferable case, not the thickness that adopts the simple main filter 410B of increasing, but have the filter of catching of two or more series connection, so that effectively increase the quantity of the filter material that air-flow must pass.In other words, make air-flow before arriving main filter 410B, must pass one or more secondary filter 520B exactly.

Under the optional situation, exist therein among a succession of embodiment that catches filter, these also can multiple

catch filter assemblies

410B and 410C realizes by increasing.This realizes by increasing the assembly lamination.In other words, the filter of catching with several series connection is better, rather than has the single filter of catching big and thickness equivalence.

In an embodiment, because air-flow is to pass each filter successively one by one, so secondary filter 520B also can be counted as with main filter 410B and is in series.

Knowledge as a setting, fan component 401 is as the air pump that air is drawn into from

frame

10 and 11 inside the pump.For the airflow rate that keeps producing, but must there be enough air capacity air feed fans to suck by fan 401.This is the reason why

frame

10 and 11 has sizable inside, so that quite the air of large volume can be positioned near the fan component.This also be why include enough air with the frame that satisfies the suction of fan 401 assemblies aspect the time per unit air capacity and require in, the next nearest just initial secondary apertures 520D of inlet and

filter assemblies

520A, 520B and 520C separate the reason of enough large spaces in main aperture 405 and

main filter assemblies

410A, 410B and 410C and the sequence.

The benefit of a series of filters

In the present embodiment, at least one secondary inlet 520D can be positioned on the outer surface of frame 10, so that can be approaching from the user of frame outside.Figure 1A shows

assembly

520A, 520B and the 520C of secondary filter with decomposition view, represent its assembly can carry out from the outside of frame 10 near and change.

In the embodiment of Figure 1A with inner main filter 410B and external secondary filter 520B and 1B, external filter 520B catches most of dust and bulky grain.This is mainly used in the internal ramp 410B of winner and catches bacteria particles.

Find that in experiment test if having only secondary filter 520B, then hand dryer 1 can reduce 79% bacteria particles from the air-flow of hand dryer ejection.Believe that this loss in efficiency is because some bacteriums have entered

frame

10 and 11 by the tiny slot between the edge of cover 10 and substrate 11.

But, experiment test demonstrates, and by in conjunction with last inlet main filter 410B and the secondary filter 520B on 405 that is positioned at the fan frame, hand dryer 1 can realize that from the air-flow 200C that is sprayed 100% removes the target of bacteria particles.

On the surface of cover 10 and wherein this is that those of unique filtration device structure are revised among the embodiment to main therein filter bits, under the preferable case, when using, when every other slot that enters frame of sealing or inlet, can realize that preferred 100% bacterium reduces.For example, the slot between frame 10 and the substrate 11 can be installed rubber washer, seals when closing with pressed towards substrate 11 with convenient cover 10.But, when cover be opened when making the bacterium access arrangement this modification weak effect some.In other words, in the present embodiment, all that in the frame is not to have a mind in when design all be sealed to the level that prevents that bacterium from entering as the slot of the air flow path of equipment.

For avoidance of doubt, the air flow path of having a mind to design of equipment can be recognized by those holes that is used to allow air communication cross of having a mind to provide, and not comprise the non-slot of having a mind to that air can non-ly enter wittingly.

In other embodiments,

secondary filter support

520A and 520C can also hold the material that a stacked package contains fragrance.In other embodiments, secondary filter not only can be carried the fragrance carrier, and can carry the filter material that is marked with the antibiotic and sterilizing material.

Filter is changed

In the present embodiment, filter actual acquisition bacteria particles and kill captive particle.As a result, after a period of time, filter can be blocked by dead bacteria particles.Therefore, in the embodiment of Figure 1A, suggestion filter or filter 410B and 520B changed in every month.

In actual use, the personnel that are responsible for the hand dryer maintenance may forget the desired filter of changing like that continually of optimum operation condition.If filter is not replaced so that blocks, then may damage motor.For example, need prevent overheated motor because the filter that blocks allows less air to enter, so motor may be overheated.

Therefore, in the modification embodiment of Fig. 6 A and 6B, bacterium catches filter for installation and comprises filter replacing mechanism, the filter material that the automatic replacing of this mechanism enough replacement filter material of energy is being used.

In the embodiment of Fig. 6 A, filter replacing mechanism comprises spool motor 700.In Fig. 6 A, what filter material adopted is the form of the volume of sheet filter material 440B, advances around spool 710 in the mode that is similar to conveyer belt.

Sheet filter material 440B crosses the secondary apertures (not shown) of the cover 10 of Fig. 6 A, so that be used as the filter of this secondary apertures.Therefore, after a period of time, 440B passes the hole along with filter material, and then after a period of time, the filter material that is using periodically is replaced filter material and replaces.

In other embodiments, sheet filter material 440B is applicable in the main filter assemblies.

The motion of spool motor 700 is to be controlled by the sequential of control spool motor and the microprocessor control unit of running.Motor 700 can be continuously or moving filter modulator material 440B discontinuously.For example, motor can every month moving filter modulator material once so that changed the filter material that is used for coverage hole in every month effectively.Under the optional situation, motor 700 can come progressive moving filter modulator material 440B with the constant very slow-speed of revolution.This can make more filter material participate in filtration treatment.Suppose that this filter material 440B often changes, as every month once, mean that then the possibility that filter that this circulation form uses gets clogged is littler.

Present embodiment has guarantees that filter material tightly filled in the guiding in the hole.

Fig. 6 B shows another kind of distortion, and wherein sheet filter material 440B forwards the next one to and finally breaks away from first spool 710A from a spool as cinestrip, and air can enter

frame

10 and 11 with not being filtered on it.This means that the user who is responsible for maintenance must change filter on time before filter fully forwards the second spool 710B to.But, the advantage of this distortion is that filter unlikely is blocked to the degree that causes fan motor 430 impaired and overheated.

To notice that the schematic illustrations of Fig. 6 A and 6B only shows the details that filter is changed the embodiment of mechanism, and in order simplifying, from Fig. 6 A and 6B, to be omitted such as other interior details of hand dryers such as fan housing.

Security feature

In the embodiment of Figure 1A, inside master's filter assemblies 410A, the 410B of Figure 1B and Fig. 3 and 410C can only change with the intraware that exposes in the frame by opening frame.

For the hand dryer of this technology, generally speaking, the step of being opened the frame of hand dryer by the user who is not trained into the electrician may increase the risk that the user gets an electric shock.

In the embodiment of Figure 1A, hand dryer 1 has electric control circuit, is used for to hand dryer 1 supply electric power.Electric control circuit has the mechanism cut off, and is used for the supply of cutting off the electricity supply when opening frame, the risk of getting an electric shock when opening frame with minimum user.

In Figure 1B, what the mechanism of cut-out adopted is the form that elasticity is installed switch 501, only starts the power supply supply when being pressed.

Fig. 2 A shows the embodiment that its cover 10 is in the present embodiment of closed condition, and Fig. 2 B shows the situation that cover 10 is in open mode.In the open mode of Fig. 2 B, the user can be near intraware, and particularly can change inner main filter 410B.

In order to remove the risk that the user gets an electric shock, the inside of cover 10 has the cut-out mechanism activator appliance or the actuator of upright mark post 502 this forms.By comparison diagram 2A and 2B, obvious when closing cover, the most advanced and sophisticated push switch 501 of mark post 502.And when cover was opened, the tip of mark post 502 was risen to leave and is closed 501, thereby not to hand dryer 1 supply electric power.

Switch 501 is positioned at and is installed on the substrate 11.The cover 10 of frame is detachably connected to substrate 11.Mark post 502 is installed on the surface, inside of cover.

In optional embodiment, pressing device (mark post) can be installed on the substrate, and switch can be installed on the inner surface of cover.

In order to realize this goal, the equipment 1 of modification has timer control circuit, is used for fan 401 is regularly activated predetermined amount of time automatically.

Therefore, the cycle of equipment 1 is activated effectively automatically the part atmosphere around the dried hand equipment is carried out sterilization.For example, timer control circuit can activate 3 minutes every half an hour.

In this modification embodiment, detector sensor 600 can also detect and not have hand.When near detector sensor 600 detects endways opening 14, not having hand, can activate hand dryer 1 automatically and make it to operate, simultaneously heated air flow with air purification mode.This has guaranteed that hand dryer 1 can not blow to cold or not hot air and has placed below the end openings 14 on hand.Therefore, timer control circuit can be with clocklike interval or activated equipment 1 discontinuously, so that equipment 1 ambient air is carried out sterilization.

In 1 year, exist in the season of higher air borne disease incident, hand dryer is had surrounding air is carried out this feature of additional functionality of sterilization particularly useful.For example, particularly useful between the influenza seasonal period.

When also having aroma materials in filter mounting, this feature also makes hand dryer play the effect of air freshener.For example, between filter mounting 410A, 410C, 520A and 520C, can comprise fragrance or fragrance matter liner.When using, this means that the surrounding air in washroom or the communal bathroom environment can be clocklike automatically and periodically to inject fragrance at interval in conjunction with timer control circuit.

When use equipment 1 is used as adding device in the surrounding air to the ambient air sterilization and/or with fragrance, do not activate heating element heater 300 under the preferable case, otherwise for example the temperature of toilet will unnecessarily increase or reach the uncomfortable level of user.

Alternatively, in certain embodiments, between this automatic active period, still can activate heating element heater 300 by timer control circuit.We find, can the superheated ambient air in this automatic cycle period chien shih heater operation.

Therefore, some embodiments of the present invention can play the effect of air sweet smelling generating device, aseptic hand dryer and surrounding air degerming device simultaneously.

In another embodiment, timer control circuit has light sensation device 504, and can selectively limit, so that only have surround lighting when the light sensation device shows, the just automatic activated equipment of timer control circuit is used for ambient air is carried out sterilization and perfuming.In other words, for example in the time of washroom or the complete dark in toilet, this function can not activate automatically.This can be applied to wherein, and the washroom diurnally uses and does not need equipment in continuous situation about turning round at night.

Chemoreleaser

In other embodiment of the embodiment of hand dryer 1 and said flow equipment, air-flow can be a discontinuity.In other words, can have for a long time not by this equipment generation working air current.

With reference to figure 8A and 8C, and the exemplary embodiment of Figure 10 B, 10C, 11B, 12C, 12D etc.Have among the embodiment of one or more release filter 410F, 410FF at these, on filter fiber, have and to become airborne active material.For example, in this embodiment, active material can be spices, perfume or even the nontoxic antibacterial material of appropriateness.

Activate in the composition at air-flow, active material effectively can become air borne in a period of time at least.For example, active material can be evaporated to steam, perhaps is diffused in the air as mist.

In the embodiment that revises, active material can become airborne releasing agent with restricted activity material at normal temperatures and pressures and combine, but, when said composition is exposed in the air-flow, releasing agent with release of active ingredients in air-flow.

An advantage using active material and combine with this releasing agent is that when not having air communication to cross equipment, it has avoided or minimized the passive diffusion of active material in atmosphere.Therefore, with even without working air current the time, active material also will continue and little by little be diffused into airborne situation and compare, may last much longer at the active material that exists on described filter.

Active material can be the combination that can become airborne any material or material at the object of the invention.For example, active material can be fragrance, eliminating smell agent or biocide.Biocide can be bactericide or pesticide.Under the preferable case, activating agent is the biocide such as the positive alkyl dimethyl benzene of saccharic acid ammonium, quaternary ammonium salt (for example, chloride), triclosan, neighbour-benzyl chlorophenol (o-benzyl chlorophenol), 2-phenylphenol and/or N-alkyl N-ethylmorpholine base sulfate.

Under the preferable case, active material is volatilizable in the normal range (NR) of environment and pressure around, but this is unimportant for the purpose of the present invention, as long as active material can keep the air borne of enough time so that bring into play its effectiveness.

Active material can be dissolved or suspended in the carrier.In case after being released to surrounding environment, this carrier can be through preparation to improve the volatility of active material.Carrier can be prepared so that stabilizing actives physically and/or chemically, degenerates along with the time preventing.For example, carrier can comprise the UV stabilizing agent, is used for reducing the degeneration of active material when active material when being exposed to sunlight at transportation or memory period.

Carrier can be at room temperature to volatilize and preferably nontoxic to animal solvent, such as water, linseed oil, appropriate organic solvent, ethanol or its mixture.It is favourable using solvent mixture, for example, and when active material comprises two kinds or have different dissolubilities or during the material of dilution attribute.Under the preferable case, when active material and/or carrier comprised volatile ingredient, releasing agent was with coating active material and/or carrier.

Releasing agent comprises following any material or combinations of substances:

(1) can contain or postpone active material becomes air borne, for example volatilization; And

(2) at normal temperatures and pressures, in still air, keep stable.

Therefore, the prescription of releasing agent and/or preparation change according to the active matter qualitative attribution that is used for application-specific.Therefore, releasing agent can with the active material compatibility, and can use the different formulations of releasing agent according to active material.Active material can be injected into, embeds or wrap up, and perhaps physically or chemically is tied to active material.Under certain preferred prescription situation according to the present invention, activating agent is included in the volatility biocide that forms microencapsulation in the releasing agent.Under another preferred form, active material is a fragrance.

Releasing agent can be to have very low under room temperature and normal pressure or almost do not have volatile solvent, gel, lotion or slurry, and this solvent, lotion or gel are only by applying the volatilization of air-flow and/or warm air.For example, active material can inject with being stabilized, be dissolved or mixed in releasing agent under room temperature and pressure, and active material is to be close to anti-volatilization at least, and sneaks into releasing agent under the preferable case.In case be exposed in the moving air, under the optional situation by the heating, then releasing agent will become volatile and/or unsettled, thereby active material is discharged in the air-flow of process.

When releasing agent comprises solvent, it under room temperature and normal pressure can be thickness with non-volatile.Suitable examples of solvents comprises the vegetable oil with heavy distillat, and for example culinary art is oily, lanolin, and aliphatic acid, for example stearic acid.

When releasing agent comprised gel, it can be a polymeric material.Polymeric material can be homopolymers or copolymer.Polymeric material can be crosslinked.

Under the preferable case, releasing agent is the form with Caplet or microencapsulation.The general diameter of microencapsulation is less than 500 μ m, and is under the preferable case in the scope of 5-200 μ m.The particularly preferred form of capsule is to have wall or the shell mould capsule that is generally spherical hollow material shell, and the material of shell is insoluble to active material.Material is generally plastic material.Plastic material can be polymer or copolymer, is crosslinked under the optional situation, and comprises the known appropriate addn that can obtain the expectation attribute under the optional situation.Plastic material can be a resin.Plastic material can be an amino resins, such as condensation product of urea-melamine-formaldehyde etc.

There is the whole bag of tricks to make this shell capsule, comprises being used at present by utilizing urea-formaldehyde or carbamide polymer to produce the in-situ polycondensation method of amino resin capsule.This process can relate to dispersion or the emulsion that forms active material, for example under the stirring condition, in the aqueous solution of urea-formaldehyde or melamine-formaldehyde pre-condensate, is used to obtain the capsule of preselected size range.By acidic catalyst can regularization condition causing the condensation of precondensate, the result obtains being separated with solution and surrounds the condensation product of the active material of dispersion, thereby produces microencapsulation.

Because capsule prevents evaporation or other losses of active material, so microencapsulation shows excellent active material and keeps performance for a long time, unless thereby the integrality of capsule wall is damaged and discharges active material, and perhaps wall breaks.Under its many preferred forms, the present invention pays close attention to has good stable storage attribute but its polymer wall loses the microencapsulation of enough structural intergrities easily when being exposed to quick flow air in still air.

Form by coacervation process under the optional situation of microencapsulation, wherein the carrier with the oil sac form is surrounded by very thin polymer thin film, this film generally is unsettled from mechanical aspects, but its hydrophobic and wet environment had resistance, this wet environment for example just exists in the public lavatory.This attribute can be used to the active material transmission, wherein transmits by mechanical force and initiates, and for example disturbs the integrality of polymer thin film by air-flow, and discharges active material.

Wherein releasing agent comprises lotion or slurry, and they can include adhesive synthetic or nature, and for example gum arabic or synthetic polymer binder are to play the effect of bond.

Releasing agent can be the micropore capsule product.Releasing agent can be the melamine polymers shell.Under the melamine polymers shell preferable case by being used to keep the microencapsulation of activating agent to form.Polymer shell can seal, and therefore can be effective to keep the volatility activating agent, such as fragrance or biocide.Can comprise fragrance and biocide simultaneously in the microencapsulation.Fragrance can be chemical reaction not to take place, therefore storage and can not worsening in same capsule.Under the optional situation, some microencapsulations can comprise fragrance, and other microencapsulations can comprise biocide etc.The mixture of microencapsulation can be stored in such as in the same devices such as filter cylinder.Microencapsulation can change dimensionally, such as in the scope of 3-500 μ m, changing, under the preferable case between 3-200 μ m, and under the more preferred situation, between 5-100 μ m.

Releasing agent can rationally be prepared, to be used for combination or to adhere to substrate in addition.Substrate can be the porous flat plate such as woven wire or plastic wire.Dull and stereotyped can have enough specifications, so that allow air to flow through.Releasing agent can be viscous enough, so that adhere to dull and stereotyped surface and himself.

Substrate can be a filter media.Filter media can be a filter fiber.Filter medium can be natural or synthetic material, depends on to use and required filter attribute.Filter medium can comprise such as cotton fabric etc. based on cellulosic fiber, perhaps such as synthetic materials such as polyester, and perhaps their combination.Substrate can inject or be coated with such as other useful materials such as carbon in addition, so that play the effect of eliminating smell agent and/or absorbent.

Releasing agent and active material can be by spraying, whitewash or roll extrusion is applied to substrate, can be disposable or alternatively layering carry out.Because air-flow is applied on the substrate, so the superficial layer of composition exhausts, thereby prior unexposed surface is exposed to surrounding environment.The combination material can provide new surface by the long-time use of moving air.

Under the preferable case, active material is included in the releasing agent of the miniature capsule form of polymer, and microencapsulation can be sprayed or be applied in addition on the substrate surface such as filter, to be installed in the filter cylinder.Microencapsulation can apply by spray milk on substrate.Suitable microencapsulation system can obtain from Reed Pacific Pty Ltd, and its name of product is " Potenza ", uses suitable additive so that the air-flow releasability to be provided under the optional situation.

Synthetic may reside in the filter cylinder of sealing, and this filter cylinder is used to preserve composition and can be easy to replace the composition of using up.Filter cylinder can comprise the container of sealing, wherein holds the composition that will store.In case composition is passed to filter cylinder, filter cylinder is vacuum-packed in the preferred case.Filter cylinder can be made by any suitable material of the described composition components of tolerance.Suitable material can comprise APET, PETG, polypropylene and polyacrylonitrile, because they have the transparency, thermoplasticity and general chemical resistance.Other materials with less transparency can comprise polyethylene and nylon.Can be because of intensity and chemical resistance and select other materials, for example aluminium or stainless steel etc.Certainly, according to described composite formula, the skilled person can select suitable material or combination of materials.

Container can comprise sealer.Sealer can be activated so that give environment on every side with the content exposure of filter cylinder.Sealer can be bent, movably, or permeable.Activate to use when exposing its content when filter cylinder is positioned in, sealer can be suitable for being activated.Sealer can be a film.Film can be made by metal forming or such as poly flexible plastic.

According to its applicable cases,, composition can be applied on the substrate of flat type of parallel distribution or series arrangement with respect to the expectation direction of use air-flow.Under the alternative situation, substrate can be the form of row, knot or amorphous fiber, thereby along with previous composition surface is exhausted gradually, the new surface of composition is exposed to surrounding air.
