The specific embodiment
The invention describes and a kind ofly can suck air from structural outer at least and then air cleaning is become at least and concerning the people breathes, reach the roughly air cleaning system of health level.Additionally, air cleaning system is used for providing warmer or more nice and cool purifying air to inside configuration.In addition, air cleaning system comprises the feature of the circulating air that purifies flow direction structure inside.In interchangeable embodiment, air cleaning system also comprises the solar energy heating element of the temperature that purifies air for the raising air cleaning system.
Air cleaning system described herein comprise allow itself and structure-integrated and the feature of air flow path is provided between the outside of structure (space outerpace) and inside (inner space).Air cleaning system can be connected to as the ventilation duct of the part of structure or air hose, makes additional holes or the through hole that the installation of air cleaning system generally need be in any wall of structure.Replacedly, any wall that usually can penetrant structure is in order to make air cleaning system be applicable to structure.Usually, air cleaning system can constitute one with structure, makes that it can purify air when structural outer enters the inside configuration zone when forcing air, and this will discuss below in further detail.
Forward accompanying drawing now to, Fig. 1 shows the embodiment of air cleaning system 100.Air cleaning system 100 comprises the housing 102 of each assembly that holds air cleaning system 100 usually.Housing 102 is formed by one or more parts, comprises can helping air cleaning system 100 is fixed on structural feature (being installing hole, securing member etc.).Additionally, the housing 102 of air cleaning system 100 accommodates blower fan 104, circulation time blower fan can force air to pass air cleaning system 100.For example, the blower fan 104 in the housing 102 is arranged to suck air from structural outer, makes it pass air cleaning system 100, then the air of new purification is discharged in the structure.Blower fan 104 can be speed-changing draught fan, makes it possible to change the speed that air passes air cleaning system 100.As described in greater detail, the rotary speed of blower fan 104 can be by the manual control of user or by programme-control.Although be described as blower fan, under the condition that does not break away from scope disclosed by the invention, can use any amount of mechanism to force air to pass air cleaning system 100 here.
General, if all structure fixtures of permission air admission building (being window, door etc.) are closed usually and air cleaning system 100 provides the enough air-flows that enter structure from the outside, then air cleaning system 100 becomes the unique external source of air that enters structure basically.Therefore, not only air cleaning system 100 can provide the unique external source of air that enters structure, but also can produce and keep pressure reduction between structure inside and outside.For example, the air when air cleaning system 100 promotes from structural outer is discharged to inside configuration with it, and air cleaning system 100 can make inside configuration have the pressure that is higher than structural outer at last.The ability of this generation of air cleaning system 100 and maintenance pressure reduction has limited any air that enters structure from the outside usually and has only passed air cleaning system 100.Therefore, residual air is revealed in total, and this may become the polluter that enters building, and it is subject to the air that leaves building usually.As following detailed description more ground, the air flow source that enters structure by restriction only passes air cleaning system 100, because when air passes air cleaning system 100, therefore the ability of the removal air pollutants of air cleaning system 100 can reduce the external contamination thing (being mycotic spore, pollen, dust, flue gas etc.) that enters inside configuration.At last, for the people who uses structure, this may help to reduce anaphylaxis, respiratory irritation be exposed to air pollutants under relevant other health problems.
As shown in Figure 1, air cleaning system 100 comprises one or more filters 106, photocatalysis element 108, ultraviolet (UV) light source 110, reflecting material 112 and chemical catalysis element 114.Additionally, still as shown in Figure 1, air cleaning system 100 also comprises venetian blind type barrier 116 and directed outlet 118.Air cleaning system 100 is installed structurally, makes venetian blind type barrier 116 contact with the air of structural outer usually, and directed outlet 118 contacts with the air of inside configuration usually.In this structure, blower fan 104 is used for sucking air from the outside, forces it to pass venetian blind type barrier 116, filter 106, photocatalysis element 108, becomes to be exposed under the UV light.Behind UV light source 110 times, blower fan 104 can continue to force air to pass chemical catalysis element 114 and directed outlet 116 before being discharged to inside configuration in air exposure.
Usually, venetian blind type barrier 116 provides the windstream that enters air cleaning system 100 entrance.Additionally, the venetian blind type feature of venetian blind type barrier 116 helps to reduce eddy current, and if can not prevent then the direct ultraviolet light radiation from air cleaning system 100 is minimized.As shown in Figure 1, when air has passed venetian blind type barrier 116, force it to pass one or more filters 106.Usually, one or more filters 106 are used for catching and eliminating the particulate matter of air various sizes.Yet, under the condition that does not break away from disclosure scope, can use the filter of any amount of the particulate matter that is designed to catch any amount type and size.
When air has passed one or more filter 106, force air to pass photocatalysis element 108 and be exposed to the UV light source 110 times.For example, photocatalysis element 108 is made of film light catalyst (as titanium dioxide), and this film light catalyst is coated in usually and allows on the element (being the venetian blind type barrier) that air passes.Similar with above-described venetian blind type barrier 116, can reuse shutter here so that minimize and reduce turbulent flow from the direct ultraviolet light radiation of air cleaning system 100.The photocatalyst coating can make airborne particulate matter (as organic compound) contact photocatalyst, in order to be exposed to ultraviolet light following time it is destroyed.Behind particulate matter contact photocatalyst, particulate matter is exposed to ultraviolet light source 110 times.As described above, ultraviolet light source 110 exciting light catalyst are to destroy airborne residual particles.Reflecting material 112 is used for raising ultraviolet light intensity and ultraviolet to the exposure of particulate matter around at least a portion ultraviolet light source 110.The ultraviolet intensity that increases and can improve the exciting light catalyst and eliminate the efficient of airborne particulate matter the exposure of particulate matter.Usually, the combination of photocatalyst and ultraviolet can be eliminated any residual particles that can not remove at the air middle filtrator effectively.Under the condition that does not break away from scope disclosed by the invention, can use the photocatalyst of any amount to eliminate airborne particulate matter.
After air has been exposed under the ultraviolet light source, force air process blower fan 104 before discharging from orientation outlet 118, pass chemical catalysis element 114, enter inside configuration then.Chemical catalysis element 114 can be barrier or the filter that is coated with chemical catalyst usually.Usually chemical catalyst is handled the ozone that forms as by-product for decomposing the air cleaning of carrying out in air cleaning system 100.As described above, ozone may be harmful to people's health, so a benefit of air cleaning system 100 is to prevent from discharging ozone.As example, can use such as the chemical catalyst that comprises manganese dioxide and decompose ozone in the air cleaning system 100.Yet, under the condition that does not break away from scope disclosed by the invention, can use the chemical catalyst of any amount that ozone is decomposed.
Additionally, directed output 118 comprises the lath that can make user's handle be directed to inside configuration from the air effluent of air cleaning system 100.Additionally, as shown in Figure 1, the current path that leads to directed output 118 can design and be configured so that it typically is cylindrical passage.Be generally columniform current path and can promote laminar flow, the expectation streamline flow from air cleaning system 100 to inside configuration finally can be provided.Yet, under the condition that does not break away from scope disclosed by the invention, the shaping current path of any amount can be set in air cleaning system 100, promote to pass the lamina air flow of air cleaning system 100.
As example, control circuit comprises the pressure measuring element of the pressure reading that can obtain inside configuration and outside.According to these measurement results, if desired, then control circuit increases or reduces fan speed, in order to realize pressure difference or scope between structure inside and outside.Pressure difference or scope can be set by the user, and perhaps can be the settings that is embedded in the pre-programmed in the air cleaning system 100.The ability of the monitoring pressure reduction of air cleaning system 100 make air cleaning system 100 can not rely on the user effectively the pressure in the response structure change, as when opening the door.
Fig. 2 is the flow chart that is used for the method 120 of control air purifier according to some embodiments.Method 120 can be used in to be determined the pressure reduction that exists and correspondingly changes fan speed between the outside of structure and inside.As shown in Figure 2, measure internal pressure 122, measure external pressure 124.Utilize one or more pressure measuring elements (as digital barometer or piezometer) can measure inside and outside pressure.Yet, can be adopted the pressure measuring element of any amount by the pressure monitor circuit of air cleaning system 100, so that the inside and outside air pressure of measurement structure at least.For example, the pressure measuring element that is used for the air pressure inside of measurement structure also can be the uniform pressure measuring cell of the external pressure of measurement structure.126, method 120 also comprises determines whether the air pressure inside of measuring fully is higher than the external pressure of measurement.If the internal pressure of measuring is higher than the external pressure of measurement fully, then do not change fan speed usually.Yet, if air pressure inside fully is not higher than external pressure, change fan speed.128, determine whether air pressure inside is too high.130, if determine that air pressure inside is with too high then reduce fan speed.132, if definite air pressure inside will be crossed low then improve fan speed.As described above, the raising of fan speed has increased and utilizes air cleaning system 100 to be discharged to air in the structure, finally causes the relative structural outer of pressure in the structure to increase.
