Technical field
The present invention relates to a kind of be used for handling flow to a space, the device of the air of the inner space of motor vehicles particularly, described device have the device of the neutral air (Neutralluft) of the such acquisition that is used in case of necessity with the device of the pending original air of multistage purification treatment and purification and is used to produce and/or load the material with olfactory sensation effect.
Background technology
By the known a kind of device that is used for to space perfuming (Beduftung) of DE10027428A1, particularly give between shop, hotel room, room, clinic, stop, the inner space perfuming that also has motor vehicles, this device particularly relate to a kind of being used on purpose and the suitable structure of the pulsed weight feed aromatic substance amount of being scheduled to accurately.Described weight feed should be controlled by microprocessor, and wherein the moment of perfuming and intensity should freely be programmed definite.Also suggestion makes the air for the treatment of perfuming be in neutrality/scentless state by a suitable multistage in case of necessity decontamination process before perfuming in DE10027428A1, causes not satisfied result because the gas that has abnormal smells from the patient is added a group of Buddhists going together on a pilgrimage.According to described document, this multistage decontamination process may further comprise the steps: eliminating particle from air to be clean, carry out ozonation treatment, the air that guides such preliminary clearning by an adsoption catalysis device to be removing gas and the steam that has abnormal smells from the patient and to also have antibacterial and microorganism, and removes redundant ozone.
The shortcoming of this known devices is, aromatic substance (Duftstoff) although weight feed can carry out with the amount of height accurate quantification, wherein because the pulsed supply, whole concentration should be variable in the larger context, but then the perfuming process of microprocessor control be programme in advance definite, therefore do not consider the variation of pressure state in air guidance system and the passenger space, and this variation can influence the concentration to the material of rationing.
Summary of the invention
Therefore, the objective of the invention is, improve the device of the described type of beginning like this, make a response thereby the control that rationing is played the material of olfactory sensation effect can fast and flexible ground changes according to virtual condition in the space for the treatment of perfuming or in the air, ducted systems, and always mate thus with the pollutional load situation (Belastungsfall) of reality.
Described purpose utilization is a kind of like this to be used to handle the device that flows to a spatial air and to realize, this device comprises and is used in case of necessity the device of neutral air that purifies the device of pending original air and be used to produce and/or load the material with olfactory sensation effect of such acquisition with the multistage purification processing procedure, this device is provided with an air velocity pick off that is used for the volume of air flow of definite current reality, and be provided with according to air velocity signal of sensor control and treat the quantitatively device of the amount of substance that plays the olfactory sensation effect of supply, wherein, described device comprises a particulate filter, and described air velocity sensor design makes its output signal can additionally be used for determining the chocking-up degree of described particulate filter with being arranged to.
According to the present invention, a kind of be used for handling flow to a space, particularly the device of the air of the inner space of motor vehicles has and is used in case of necessity the device of neutral air that purifies the device of pending original air and be used to produce and/or load such acquisition of the material with olfactory sensation effect with the multistage purification processing procedure, in described air processor, imagine, by an actual air volume flow that the air velocity sensor measurement is current, and treat the quantitatively amount of substance that plays the olfactory sensation effect of supply according to air velocity signal of sensor control.
Promptly verified, flow to the passenger space of motor vehicles of a space-for example-the volume of air flow, even even when carrying and when blower speed is constant, also tangible fluctuation can take place by an aerator.Clearly described fluctuation is because the air drag variation in the air line of the air guidance system of connection said apparatus and corresponding air intake and air outlet slit causes.The variation of described air drag for example can be caused by the change in location of aerator valve/valve (Klappen), perhaps for motor vehicles owing to the variation of travel speed, switch to from the fresh air operation that circulating air operation etc. causes, particularly owing to open vehicle window and/or the roof skylight causes.If when determining the aromatic substance amount, do not consider this fluctuation in the described volume of air flow, the rationing that this fluctuation will lead to errors.
Amount and the volume of air flow of current reality of the present invention by making rationing is complementary and overcome the problems referred to above simply.
Have reproducible relation as long as can guarantee output signal and air flowing volume, then described air velocity pick off can be arranged on the optional position in the air guidance system.The described downstream that for example preferably is installed in the particulate filter of the device that is present in the air condition that is used for the inner space usually as the air velocity pick off that comprises slotted line layout that illustrates below.Described particulate filter also is the ingredient of air intake filter for installation usually except that an active carbon filter, and described air intake filter for installation can filter out granule, dust, gas and steam from the original air that flows into by air intake.Described air velocity transducer arrangements is made the degree of congestion of monitor filter simply in the downstream of particulate filter, for example the reference speed of the filter that does not load by the real output signal and with the air velocity pick off compares.A signal maintenance calculations machine of input (Servicerechner) that obtains thus also correspondingly can be shown.When surpassing a ultimate value, can indicate necessary filter to change.Guarantee in time to find plugged filter by monitor filter.Particulate filter can have the small construction size thus, and also more common storage level (Reserve) no longer is essential in the filter design at present.
The known in addition so-called combined filter that mainly comprises the particulate filter of one and one active carbon filter combination.This can be for example realizes by the active carbon layer on the particulate filter of being made by a kind of filtering material such as adhesive-bonded fabric.Clearly, for this combined filter, the air velocity pick off also is arranged in the downstream of filter.
It itself is known carrying out the filter monitoring by an air velocity pick off, for example by EP0847787A1.But the supply of material that the olfactory sensation effect is arranged is controlled simultaneously and be not known according to the air velocity signal of sensor.
There is the material of olfactory sensation effect to add in the carrier bulk stream by modes such as sprinkling, evaporation, vaporizations.Also can imagine by a part of volume flow and add.Described method and corresponding device thereof are known., according to an air velocity signal of sensor that is arranged in the air guidance system amount of adding is controlled according to the present invention, for example for spraying length and the number of times that pulse is sprayed in control, perhaps for evaporation control temperature.In servicely at circulating air suitablely under individual cases be, will reduce a correcting value, improve (Anreicherung) continuously with the concentration of aromatic substance in the space that prevents to treat perfuming by the aromatic substance amount for the treatment of quantitatively supply that the air velocity pick off obtains.This individual cases have only for example when just not occurring under the filtering situation in service not the carrying out of circulating air.
The air velocity pick off is known and has illustrated in the literature.Its action principle is can be because the variation that air flowing takes place according to the resistance of slotted line or one group of slotted line.The present invention does not carry out any restriction in the selection of suitable air velocity pick off.
When existence was used to carry the aerator of air, described air velocity signal of sensor can also be used for additionally causing along with the increase of the obstruction of particulate filter that the volume of air flow is reduced to a certain degree compensates by heightening aerator voltage.Described signal can also be used for the variation of compensation integral flow resistance in a similar fashion, and described variation for example is because the variation of current drainage valve/valve or back pressure valve/valve (Staudruckklappe) causes.
In a preferred implementing form of the present invention, the described material that plays the olfactory sensation effect comprises ion and/or ozone.Known ion or ozone with less amount weight feed can allow the people produce the sensation of fresh air.Therefore also have corresponding ionizing or ozonisation device according to device of the present invention, wherein the addition of ion and/or ozone is controlled by described air velocity pick off according to the present invention.The ozone or the ionic air cleaning effect that realize by the oxidation to harmful substance repeatedly have been described in the literature.But it is also disputable about this effect.But the present invention does not get rid of and additionally uses corresponding ionizing or ozonisation device.
In another preferred implementing form of the present invention, be provided with an air mass sensor that is used for the concentration of narmful substance of definite original air of importing from the outside.This air mass sensor has such advantage, gets final product so that the intensity of removing harmful substance and the amount of in esse harmful substance are complementary.This also to the back pass through add air-treatment that the material of its olfactory sensation effect carries out and play a part favourablely handle because preferably neutral air is carried out perfuming.Adding aromatic substance in the air that carries odoring substance can allow the people do not feel like oneself usually.
Air mass sensor is known.Its action principle mainly is the variation of measuring resistance according to when oxidable or reducible air harmful substance occurring usually.But the invention is not restricted to use specific air mass sensor type.
As long as be provided with circulating air operation (mode); as for example for the situation of motor vehicles; described air mass sensor also can additionally be used for switching to the circulating air operation by control circulating air valve/valve (Umluftklappe) when the original air from outside input has the high harmful substance amount of carrying, to protect Vehicular occupant.Switch to circulating air and move the advantage that also has on the other filtering technique, promptly can reduce by harmful substance being arranged on the circulating air valve load of the air intake filter effect of face behind the door usually.For example the amount of active carbon is less can to keep sorptive material in the adsorptivity filter thus, and formed thus flow passage resistance is lower.Can reduce the size of member on the whole.When having the filter of common physical dimension and conventional amounts of activated carbon, employing can correspondingly prolong its service life.
In addition advantageously, be provided with an air mass sensor that is used to treat the inner space of perfuming because inner air may be for example since the medicated cigarette flue dust perhaps also can pollute owing to there is serious harmful substance in the new car discharging.Therefore for example the output signal of inner air mass sensor can be used for controlling aerator voltage, control by this way, promptly when the pollution of the internal portion of harmful substance air raises, improve aerator voltage and improve blower speed thus, change thereby quicken air.Identical with the situation of extraneous air mass sensor, high-intensity air cleaning has also been handled favourable effect to perfuming in this case.
When having an outside and an inner air mass sensor, for example can realize control by the output signal that contrasts inside and outside air mass sensor to circulating air valve position.This can carry out like this, promptly switches to the circulating air running status when the harmful substance pollution level of fresh air is high.On the contrary, the medicated cigarette flue dust is elevated to the degree that the extraneous air pollution is lower than the inner air pollution if the harmful substance of vehicle interior for example pollutes, and then switches to fresh air again.
According to the application scenario difference, will device according to the present invention be designed to install simply-for example insert-may be favourable to there being the module in conditioner or the heater.
But according to device of the present invention also can with act on purify and handle have high internal institution space harmful substance pollute-for example because the medicated cigarette flue dust-the inner space in the solution of " independence " of air, for example after big in the passenger space of railway carriage or compartment taxi.In this application scenario, purify and handle the inner space air according to the mode of circulating air operation by the module of the passenger space of packing into.
Can realize by this way also according to device of the present invention that in addition promptly its parts are not to be arranged to a compact module, but be arranged on the pre-position of conditioner or heater individually.Here suitable is, and all parts concentrate is connected on the air conditioner electronic device.
Generally can be used for purifying and handling the air that is supplied to any inner space according to device of the present invention.Described device is particularly suitable for being used for motor vehicles.
