Abstract

The present invention relates to a system for detecting washing machines removable basket, which comprises at least one washing basket ( 1 ) attached to the washing machine, at least one washing basket ( 2 ) removable from the washing machine and at least one structural component ( 3 ) attached to the washing machine. The system itself consists of at least one sensor ( 4 ) and at least one component ( 5 ) able to cause excitation in the sensor ( 4 ), wherein the sensor ( 4 ) can be physically associated to the structural component ( 3 ) attached to the washing machine and the component ( 5 ) can be physically associated with the washing basket ( 2 ) removable from the washing machine. Alternatively, the sensor ( 4 ) can be physically associated to the washing basket ( 2 ) removable from the washing machine and the component ( 5 ) may be physically associated to the structural component ( 3 ) attached to the washing machine. The subject method provides for at least one driving step of the motive source ( 6 ) and at least one checking step of the output signal of the sensor ( 4 ), the detection of the removable washing basket ( 2 ) being performed by checking the change of the output signal of the sensor ( 4 ).

First claim

The invention claimed is:

1. A washing machine, comprising:
a first washing basket attached to the washing machine;
a second washing basket configured to be removable from the washing machine;
a structural component, which is annularly shaped and is attached to the washing machine;
a sensor; and
a part configured to cause excitation of the sensor,
wherein:
the sensor is located on the structural component, and
the part is located on the second washing basket.

2. The system according to claim 1 , wherein the sensor comprises an inductive sensor.

3. The system according to claim 1 , wherein the sensor comprises a magnetic sensor.

4. The system according to claim 1 , wherein the sensor comprises an electromagnetic sensor.

5. The system according to claim 1 , wherein the sensor comprises an optical sensor.

6. The system according to claim 1 , wherein the part comprises a magnet.

7. The system according to claim 1 , wherein the part comprises an electromagnet.

8. The system according to claim 1 , wherein the part comprises a light source.

9. The system according to claim 1 , wherein the part comprises a refractive element.

10. A washing machine, comprising:
a first washing basket attached to the washing machine;
a second washing basket configured to be removable from the washing machine;
a structural component, which is annularly shaped and is attached to the washing machine;
a sensor; and
a part configured to cause excitation of the sensor,
wherein:
the sensor is located on the second washing basket, and

the part is located on the structural component.

11. The system according to claim 10 , wherein the sensor comprises an inductive sensor.

12. The system according to claim 10 , wherein the sensor comprises a magnetic sensor.

13. The system according to claim 10 , wherein the sensor comprises an electromagnetic sensor.

14. The system according to claim 10 , wherein the sensor comprises an optical sensor.

15. The system according to claim 10 , wherein the part comprises a magnet.

16. The system according to claim 10 , wherein the part comprises an electromagnet.

17. The system according to claim 10 , wherein the part comprises a light source.

18. The system according to claim 10 , wherein the part comprises a refractive element.

19. A method for detecting a removable basket of a washing machine, the method comprising:
activating a motive source of the washing machine;
checking an output signal of a sensor of the washing machine;
detecting a change of the output signal of the sensor; and
determining a presence or an absence of the removable basket if the change of the output signal of the sensor is detected;
wherein:
the sensor is located on an annularly shaped structural component attached to the washing machine,
a part is located on the removable basket, the part is configured to cause excitation of the sensor, and
the motive source is configured to be operatively connected to the removable basket.

20. The method according to claim 19 , wherein the activating step of the motive source comprises a rotary driving of at least one complete mechanical turn.

21. The method according to claim 19 , wherein the activating step of the motive source is interrupted at an instant wherein a change in the output of the sensor is detected.

22. The method according to claim 19 , wherein the activating step of the motive source is performed before an initial step of a washing process.

23. The method according to claim 19 , wherein the determining the presence of the removable basket is performed by comparing the change of the output signal of the sensor and a predetermined analog parameter.

24. The method according to claim 19 , wherein the determining the presence of the removable basket is performed by checking at least one peak of the output signal of the sensor.

25. The method according to claim 19 , wherein the determining the absence of the removable basket is detected by checking a maintenance of the output signal of the sensor along at least one activating step of the motive source.

26. A method for detecting a removable basket of a washing machine, the method comprising:
activating a motive source of the washing machine;
checking an output signal of a sensor of the washing machine;
detecting a change of the output signal of the sensor; and
determining a presence or an absence of the removable basket if the change of the output signal of the sensor is detected;
wherein:
the sensor is located on the removable basket,
a part is located on an annularly shaped structural component attached to the washing machine, the part is configured to cause excitation of the sensor, and
the motive source is configured to be operatively connected to the removable basket.

27. The method according to claim 26 , wherein the activating step of the motive source comprises a rotary driving of at least one complete mechanical turn.

28. The method according to claim 26 , wherein the activating step of the motive source is interrupted at an instant wherein a change in the output of the sensor is detected.

29. The method according to claim 26 , wherein the activating step of the motive source is performed before an initial step of a washing process.

30. The method according to claim 26 , wherein the determining the presence of the removable basket is performed by comparing the change of the output signal of the sensor and an analog parameter previously known.

31. The method according to claim 26 , wherein the determining the presence of the removable basket is performed by checking at least one peak of the output signal of the sensor.

32. The method according to claim 26 , wherein the determining the absence of the removable basket is detected by checking a maintenance of the output signal of the sensor along at least one driving step of the motive source.
