Abstract

A device for dispensing a fragrance includes a container which has at least one outlet opening and is used for receiving the fragrance. Associated to the container is an electric heating element for heating the fragrance and a temperature sensor for detecting the temperature of the fragrance. The electrical heating element is controlled by a controller as a function of the temperature detected by the temperature sensor.

First claim

The invention claimed is:

1. A device for dispensing a fragrance, comprising:
a container receiving the fragrance and having an outlet opening for discharge of the fragrance, said container including an air access opening comprising a tube configured to be connected to a ventilation and/or air conditioning system of a motor vehicle, wherein the ventilation and/or air conditioning system generates an air flow which is fed via the tube and the air access opening to the container so as to expose the fragrance in the container to an air flow;
an electric heating element operably connected to the container for heating the fragrance, said electrical heating element configured as a film having at least one conductor path which is heatable when applying a voltage, said film being arranged at least on an inner surface of the container;
a temperature sensor configured to detect a temperature of the fragrance in the container; and
a controller configured to control the electrical heating element as a function of the temperature detected by the temperature sensor.

2. The device of claim 1 , further comprising a heat insulation layer configured to at least partially surround the container.

3. The device of claim 2 , wherein the heat insulation layer is made of foamed plastic.

4. The device of claim 1 , wherein the controller is configured to heat the fragrance to a temperature between 10° C. and 30° C.

5. The device of claim 1 , wherein the controller is configured to heat the fragrance to a temperature of approximately 20° C.

6. A motor vehicle, comprising a device for dispensing a fragrance, said device comprising:
a container receiving the fragrance and having an outlet opening for discharge of the fragrance, said container including an air access opening comprising a tube configured to be connected to a ventilation and/or air conditioning system of the motor vehicle, wherein the ventilation and/or air conditioning system generates an air flow which is fed via the tube and the air access opening to the container so as to expose the fragrance in the container to an air flow,
an electric heating element operably connected to the container for heating the fragrance, said electrical heating element configured as a film having at least one conductor path which is heatable when applying a voltage, said film being arranged at least on an inner surface of the container,
a temperature sensor configured to detect a temperature of the fragrance in the container, and
a controller configured to control the electrical heating element as a function of the temperature detected by the temperature sensor.

7. The motor vehicle of claim 6 , wherein the device comprises a heat insulation layer configured to at least partially surround the container.

8. The motor vehicle of claim 7 , wherein the heat insulation layer is made of foamed plastic.

9. The motor vehicle of claim 6 , wherein the controller is configured to heat the fragrance to a temperature between 10° C. and 30° C.

10. The motor vehicle of claim 6 , wherein the controller is configured to heat the fragrance to a temperature of approximately 20° C.

11. The motor vehicle of claim 6 , further comprising an on-board electrical system, said electrical heating element of the device being connected to the on-board electrical system of the motor vehicle.

12. The motor vehicle of claim 6 , wherein the air access opening is located at a distance to the outlet opening, said access opening configured to allow the air flow to enter the container and pick up the fragrance as it evaporates, for discharge through the outlet opening.

13. The motor vehicle of claim 12 , wherein the air access opening and the outlet opening are arranged on a topside of the container.
