Abstract

A method for fragrancing and/or deodorizing a cleaning appliance is disclosed. The method involves capturing first information or obtaining captured first information indicative of an odor load in the interior of the cleaning appliance, producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce fragrancing and/or deodorizing information of this type, and initiating fragrancing and/or deodorization by employing at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced. A corresponding dosing device, a device for carrying out and/or controlling the method, and a system with one or more devices for carrying out and/or controlling the method are also disclosed.

Claims (29)

1. A method carried out by one or more devices, comprising:

capturing first information or obtaining captured first information indicative of an odor load in the interior of a cleaning appliance, wherein the first information is captured from at least one odor sensor;

producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce the fragrancing and/or deodorizing information, wherein the production of the fragrancing and/or deodorizing information comprises a comparison between the captured or obtained first information and a predefined threshold;

initiating fragrancing and/or deodorization by at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced;

obtaining a user input concerning an adjustment of the predefined threshold; and

adapting the predefined threshold based on the obtained user input.

2. The method as claimed in claim 1 , wherein the captured or obtained first information and/or the predefined threshold are indicative of at least one of the following parameters:

an intensity of the odor load in the interior of the cleaning appliance;

a type of the odor load in the interior of the cleaning appliance;

dynamics of the odor load in the interior of the cleaning appliance;

or a combination thereof.

3. The method as claimed in claim 1 , the method further comprising:

capturing second information or obtaining captured second information indicative of an ingress of light and/or a temperature in the interior of the cleaning appliance, wherein the second information is captured by at least one light sensor and/or at least one temperature sensor.

4. The method as claimed in claim 3 , the method further comprising:

adapting the predefined threshold based on the captured second information.

5. The method as claimed in claim 3 , wherein the at least one odor sensor and the at least one light sensor and/or the at least one temperature sensor form a sensor array.

6. The method as claimed in claim 1 , wherein the method is carried out and/or controlled between two cleaning cycles of the cleaning appliance.

7. The method as claimed in claim 1 , wherein initiation of the fragrancing and/or deodorization releases different fragrancing and/or deodorizing agents.

8. The method as claimed in claim 1 , wherein initiation of the fragrancing and/or deodorization releases different quantities of the fragrancing and/or deodorizing agent.

9. The method as claimed in claim 3 , wherein the method further comprises:

adapting the predefined threshold by a zero point calibration when the temperature has dropped below a predefined temperature threshold and the ingress of light has signaled emptying of the cleaning appliance.

10. The method as claimed in claim 7 , wherein the initiation of the fragrancing and/or deodorization releases the different fragrancing and/or deodorizing agents as a function of a type of the odor load in the interior of the cleaning appliance.

11. The method as claimed in claim 8 , wherein the initiation of the fragrancing and/or deodorization releases the different quantities of the fragrancing and/or deodorizing agent as a function of an intensity of the odor load in the interior of the cleaning appliance.

12. A method carried out by one or more devices, comprising:

capturing first information or obtaining captured first information indicative of an odor load in the interior of a cleaning appliance, wherein the first information is captured from at least one odor sensor;

producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce the fragrancing and/or deodorizing information, wherein the production of the fragrancing and/or deodorizing information comprises a comparison between the captured or obtained first information and a predefined threshold;

initiating fragrancing and/or deodorization by at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced;

capturing second information or obtaining captured second information indicative of an ingress of light and/or a temperature in the interior of the cleaning appliance, wherein the second information is captured by at least one light sensor and/or at least one temperature sensor; and

adapting the predefined threshold by a zero point calibration when the temperature has dropped below a predefined temperature threshold and the ingress of light has signaled emptying of the cleaning appliance.
