Problems solved by technology

[0003] The disadvantage of this known device is that although the dosing of the aroma can take place in a highly precise dosing amount, wherein due to the pulsed supply, the overall concentration should be variable within a relatively large range, the On the other hand, the microprocessor-controlled perfuming process is pre-programmed and therefore does not take into account changes in the pressure state in the air guidance system and in the passenger space, which would affect the concentration of the dosing substance

Embodiment Construction

[0032] FIG. 1 shows a device according to the invention designed as a module 1 . The module 1 comprises a housing 2 with an air inlet 2a and an air outlet 2b, which can be designed, for example, as a die-cast receiving frame. Arranged in the housing 2 in the flow direction is an air quality sensor 3 and an air inlet filter arrangement 4 with a combined filter. The air inlet filter device 4 is sealed against the wall of the housing 2 by means of a sealing element 5 . According to the invention, an air velocity sensor 6 is provided directly downstream of the air inlet filter arrangement 4 . The air speed sensor 6 is used to determine the current actual air volume flow and thus not only allows an essentially precise determination of the quantity of the dosed material, but also provides information on the filter load or filter consumption. In addition, an ionization and / or ozonation device 7 and an aromatization device 8 are provided downstream of the air inlet filter device 4 ....

Abstract

The invention relates to an arrangement for conditioning air which is to be introduced into a space, especially the interior space of a motor vehicle, said arrangement comprising devices (4, 4a, 4b) for purifying the air to be conditioned in an optionally multi-stage purification process, and devices (7, 8) for producing and / or supplying the neutral air thus obtained with substances having an olfactive action. According to the invention, the arrangement is provided with an air speed sensor (6) for determining the respective actual air volume flow rate, and means for controlling the quantity of olfactive substances to be dosed, according to the output signal of the air speed sensor (6).

Description

technical field [0001] The invention relates to a device for treating air supplied to a space, in particular a vehicle interior of a motor vehicle, which has a device for purifying the raw air to be treated, if necessary in a multi-stage purification process, and a device for Device for generating and / or loading the thus obtained neutral air with substances having an olfactory effect. Background technique [0002] Known from DE10027428A1 is a device for perfuming spaces, in particular shops, hotel rooms, clinic rooms, lodging rooms, and the interior of motor vehicles, which relates in particular to a Appropriate structure for the purposeful and precise pulsed dosing of a predetermined amount of aroma. The dosing should be controlled by a microprocessor, wherein the timing and intensity of the aromatization should be freely programmable. It is also proposed in DE 10027428A1 to render the air to be perfumed neutral / odor-free by means of a suitable, if necessary, multi-stage ...
