Monitoring of loading and/or unloading of dishwasher machines

1. A method, comprising the steps of:

acquiring at least one set of acceleration data indicative of a progression of measured acceleration values, wherein the at least one set of acceleration data is acquired by at least one acceleration sensor in a treatment chamber of a dishwasher;

determining at least one set of evaluation data based at least in part on the acquired at least one set of acceleration data, wherein determining the at least one set of evaluation data comprises:

determining whether one or more characteristic actions have been performed by a user, and if so, performing the following:

storing action data representing the one or more characteristic actions that are included in the determined at least one set of evaluation data or that are at least a part of the determined at least one set of evaluation data;

outputting or causing the output of the determined at least one set of evaluation data; and

determining control data at least partially based on the at least one set of evaluation data, wherein the control data causes a dosing device to perform a dosing of cleaning and/or care agent defined according to the control data.

2. The method according to claim 1 , wherein the at least one set of acceleration data is acquired with respect to a predefined orientation and/or placing of the at least one acceleration sensor in the treatment chamber of the dishwasher.

3. The method according to claim 2 , further comprising:

placing the at least one acceleration sensor inside the treatment chamber of the dishwasher, so that the predefined positioning and/or orientation of the at least one acceleration sensor inside the treatment chamber of the dishwasher is present.

4. The method according to claim 1 , wherein determining the at least one set of evaluation data is performed while the acquisition of the at least one set of acceleration data is continued.

5. The method according to claim 1 , wherein the one or more characteristic actions of the user are represented by one or more of the following actions i) to iv):

i) loading or unloading an object into or from the treatment chamber of the dishwasher;

ii) pulling out or sliding back a basket of the treatment chamber of the dishwasher;

iii) opening or closing a door closing the treatment chamber of the dishwasher;

(iv) rinsing cycle of a cleaning program to be carried out by the dishwasher.

6. The method according to claim 5 , whereby the object which is placed in or removed from the treatment chamber of the dishwasher is at least a piece of cutlery or crockery.

7. The method according to claim 1 , further comprising:

acquiring or obtaining one or more sets of sensor data, said one or more sets of sensor data being indicative of a temperature or brightness inside the treatment chamber of the dishwasher, wherein determining the at least one set of evaluation data is further based at least in part on said one or more sets of sensor data.

8. The method according to claim 7 , wherein the at least one set of acceleration data and/or the one or more sets of sensor data are acquired over a predefined period of time.

9. The method according to claim 1 , wherein the at least one set of acceleration data represents a signal in the direction of each of two or three degrees of freedom.

10. The method according to claim 9 , wherein the determination of the at least one set of evaluation data is performed separately for each of the two or three degrees of freedom.

11. The method according to claim 10 , wherein determining the at least one set of evaluation data is further at least partially based on a nominal capacity of the treatment chamber of the dishwasher.

12. The method according to claim 1 , wherein the determined at least one set of evaluation data is indicative of a rinsing cycle and/or a loading or unloading of an object placed inside the treatment chamber of the dishwashers and/or a size of an object placed in or removed from a basket placed inside the treatment chamber of the dishwasher, so that the at least one set of evaluation data is further indicative of a load condition of the treatment chamber of the dishwasher.

13. The method according to claim 1 , wherein determining the at least one set of evaluation data further comprises:

determining a time response of an oscillation at least partially based on the at least one set of acceleration data, the oscillation being represented by the progression of the measured acceleration values from the at least one set of acceleration data, the time response being indicative of a size of an object placed in or removed from the treatment chamber of the dishwasher.

14. A device configured to execute and/or control the method according to claim 1 .

15. The device according to claim 14 , wherein the device is configured to place the at least one acceleration sensor in a predefined orientation in the treatment chamber of the dishwasher.

16. The device according to claim 15 , wherein the at least one acceleration sensor is configured to measure acceleration in each of at least 2 degrees of freedom.

17. The device according to claim 14 , wherein the device is configured to determine the one or more characteristic actions performed by the user, wherein the one or more characteristic actions comprise one or more of the following actions i) to iv):

i) loading or unloading an object into or from the treatment chamber of the dishwasher;

ii) pulling out or sliding back a basket of the treatment chamber of the dishwasher;

iii) opening or closing a door closing the treatment chamber of the dishwasher; and

(iv) rinsing cycle of a cleaning program to be carried out by the dishwasher.

18. The device according to claim 14 , wherein the device is further configured to acquire one or more sets of sensor data, said one or more sets of sensor data being indicative of a temperature or brightness inside the treatment chamber of the dishwasher, wherein determining the at least one set of evaluation data is further based at least in part on said one or more sets of sensor data.

19. A computer program comprising program instructions which cause a processor to execute and/or control the method according to claim 1 when the computer program is executed on the processor.

20. A device configured to:

acquire at least one set of acceleration data indicative of a progression of measured acceleration values, wherein the at least one set of acceleration data is acquired by at least one acceleration sensor in a treatment chamber of a dishwasher;

determine at least one set of evaluation data based at least in part on the acquired at least one set of acceleration data; and

output or cause the output of the determined at least one set of evaluation data,

wherein:

the at least one acceleration sensor is placed in a predefined orientation in the treatment chamber of the dishwasher and is configured to measure acceleration in each of at least 2 degrees of freedom, and

the at least one set of evaluation data is determined by:

determining whether one or more characteristic actions have been performed by a user, and if so, performing the following:

storing action data representing the one or more characteristic actions that are included in the determined at least one set of evaluation data or that are at least a part of the determined at least one set of evaluation data.
