Abstract

The invention relates to a fragrancing device comprising a housing, a fragrance cartridge, a closure element and a blower, wherein the fragrance cartridge and/or the blower and/or the closure element is arranged inside the housing and the housing has a first opening and a second opening, wherein an air flow can flow through the housing from the first opening to the second opening, wherein the fragrance cartridge can be exposed and closed by the closure element, wherein the first opening and/or the fragrance cartridge is arranged upstream of the blower relative to the air flow direction in the housing and the second opening is arranged downstream of the blower relative to the air flow direction in the housing.

First claim

The invention claimed is:

1. A fragrancing device having a housing, having a fragrance cartridge, having a closure element and having a blower, wherein the fragrance cartridge and/or the blower and/or the closure element are arranged inside the housing and the housing comprises a first opening and a second opening, wherein the housing is traversable with an air flow from the first opening toward the second opening, wherein the fragrance cartridge is openable and closable by means of the closure element, wherein the first opening and/or the fragrance cartridge is arranged in the housing upstream of the blower with reference to the air flow direction and the second opening is arranged in the housing downstream of the blower with reference to the air flow direction, wherein the fragrance cartridge and the closure element are realized integrally as a structural unit.

2. The fragrancing device as claimed in claim 1 , wherein a fragrance chamber, which comprises an air volume which is saturatable with fragrance, is provided inside the fragrance cartridge.

3. The fragrancing device as claimed in claim 1 , wherein the pressure generated by the blower in the region of the fragrance cartridge is lower than in a region directly behind the blower.

4. The fragrancing device as claimed in claim 1 , wherein a gas chamber is provided inside the housing, wherein a fluid communication is producible between the gas chamber and the fragrance chamber of the fragrance cartridge by opening the closure element.

5. The fragrancing device as claimed in claim 1 , wherein the fragrance can be sucked out of the gas chamber by the blower.

6. The fragrancing device as claimed in claim 1 , wherein a carrier material which can be permeated with a fragrance is arranged inside the fragrance cartridge.

7. The fragrancing device as claimed in claim 1 , wherein the housing comprises a third opening through which the fragrance cartridge is insertable into the housing or removable from the housing.

8. The fragrancing device as claimed in claim 1 , wherein the fragrance cartridge and/or the closure element can be flowed around by an air flow.

9. The fragrancing device as claimed in claim 1 , wherein the blower is formed by a radial blower or an axial blower.

10. The fragrancing device as claimed in claim 1 , wherein a plurality of fragrance cartridges are providable, wherein a singular number of fragrance cartridges or a plurality of fragrance cartridges are closable by one closure element or by several closure elements.

11. The fragrancing device as claimed in claim 1 , wherein in the interior the housing realizes a plurality of flow paths which are separate from one another, wherein one or several fragrance cartridges are assigned to each flow path.

12. An air-conditioning system having a fragrancing device as claimed in claim 1 , wherein the fragrancing device is arranged inside an air-conditioning housing or on an air-conditioning housing and fragrance is flowable through the second opening of the fragrancing device into a flow channel inside the air-conditioning system or fragrance is flowable through the second opening of the fragrancing device into a flow channel which is separate from the air-conditioning system.

13. An air-conditioning system having a fragrancing device having a housing, having a fragrance cartridge, having a closure element and having a blower, wherein the fragrance cartridge and/or the blower and/or the closure element are arranged inside the housing and the housing comprises a first opening and a second opening, wherein the housing is traversable with an air flow from the first opening toward the second opening, wherein the fragrance cartridge is openable and closable by means of the closure element, wherein the first opening and/or the fragrance cartridge is arranged in the housing upstream of the blower with reference to the air flow direction and the second opening is arranged in the housing downstream of the blower with reference to the air flow direction, wherein the fragrancing device is arranged inside an air-conditioning housing or on an air-conditioning housing and fragrance is flowable through the second opening of the fragrancing device into a flow channel inside the air-conditioning system or fragrance is flowable through the second opening of the fragrancing device into a flow channel which is separate from the air-conditioning system.
