Abstract

A device that has a component within a process air circuit of a washer dryer or tumble dryer; a condensate water trough in which condensate water is collected that is formed in the process air circuit as a result of drying damp laundry; and a first lever arm rotatably fastened to a rinse tank above the component. The component is to be cleaned and the condensate water is conducted from the condensate water trough to the rinse tank. Further, the condensate water is dispensed from an outlet opening of the rinse tank to the component. The rinse tank has a closure to selectively open and close the outlet opening and an actuator to actuate the closure. Also, the closure has a sealing head that is connected to the first lever arm and that closes the outlet opening.

First claim

The invention claimed is:

1. A device, comprising:
a component to be cleaned, the component configured to be located within a process air circuit of the device;
a condensate water trough configured to collect condensate water formed in the process air circuit as a result of drying damp laundry;
a rinse tank positioned above the component and having an outlet opening;
a first lever arm rotatably fastened to the rinse tank, a second lever arm positioned outside of the rinse tank and coupled to the first lever arm, and a sealing head connected to the first lever arm and configured to close the outlet opening; and
an actuator configured to actuate the second lever arm to selectively open and close the outlet opening,
wherein the device is configured to conduct the condensate water from the condensate water trough to the rinse tank,
wherein the sealing head is configured to be opened to dispense the condensate water from the outlet opening of the rinse tank onto the component,
wherein the rinse tank is removable from the device such that the first lever arm, the second lever arm, and the sealing head are removable with the rinse tank, and
wherein the actuator is fastened on a receiving opening configured to guide the rinse tank.

2. The device of claim 1 , wherein the component is an evaporator of a condenser.

3. The device of claim 1 , wherein the actuator is set up and disposed to apply a force to the second lever arm.

4. The device of claim 1 , wherein the actuator has a lifting magnet.

5. The device of claim 1 , wherein the actuator further comprises a plunger, said plunger configured to apply a lifting movement to the second lever arm.

6. The device of claim 1 , wherein a lifting path of the actuator has a maximum travel of 30 mm.

7. The device of claim 6 , wherein the maximum travel is 25 mm.

8. The device of claim 1 , wherein the actuator is configured to travel through a lifting path in less than 2 seconds.

9. The device of claim 8 , wherein the actuator is configured to travel through a lifting path in less than 0.5 seconds.

10. The device of claim 9 , wherein the actuator is configured to travel through a lifting path in less than 0.2 seconds.

11. The device of claim 1 , further comprising a claw coupling to couple the first lever arm and the second lever arm.

12. The device of claim 1 , further comprising a sealing element configured to seal a through opening between the first and second lever arms.

13. The device of claim 1 , further comprising a spring element configured to press the sealing head onto the outlet opening.

14. The device of claim 1 , wherein the device is one of a washer dryer and a tumble dryer.

15. The device of claim 1 , wherein the first lever arm is rigidly connected to the sealing head.

16. The device of claim 13 , wherein the spring element is configured to apply a rotational force to the first lever arm.

17. The device of claim 13 , further comprising a shaft, wherein the first lever arm is rotatable about the shaft, and the spring element is located on the shaft.

18. The device of claim 1 , wherein the device is adapted to deliver between 75 and 150 liters per minute of the condensate water to the component.

19. The device of claim 18 , wherein the device is adapted to fully dispense the condensate water within two seconds.

20. The device of claim 1 , wherein the first lever arm is rotatably fastened to the rinse tank such that the outlet opening remains closed by the sealing head when the rinse tank is removed from the device.

21. A method for operating a device having a component to be cleaned, said component located within a process air circuit of the device; a condensate water trough configured to collect condensate water formed in the process air circuit as a result of drying damp laundry; a rinse tank positioned above the component and having an outlet opening; a first lever arm rotatably fastened to the rinse tank, a second lever arm positioned outside of the rinse tank and coupled to the first lever arm, and a sealing head connected to the first lever arm and configured to close the outlet opening; and an actuator configured to actuate the second lever arm to selectively open and close the outlet opening; wherein the device is configured to conduct the condensate water from the condensate water trough to the rinse tank, the method comprising:
actuating the actuator to apply a force to the second lever arm to open the outlet opening; and
lifting the sealing head from the outlet opening by the first lever arm as a result of the actuator applying the force to the second lever arm to dispense the condensate water from the outlet opening of the rinse tank onto the component,
wherein the rinse tank is removable from the device such that the first lever arm, the second lever arm, and the sealing head are removable with the rinse tank, and
wherein the actuator is fastened on a receiving opening configured to guide the rinse tank.

22. The method of claim 21 , wherein the first lever arm is rotatably fastened to the rinse tank such that the outlet opening remains closed by the sealing head when the rinse tank is removed from the device.

23. The method of claim 21 , wherein the device is one of a washer dryer and a tumble dryer.

24. A laundry appliance comprising:
a process air circuit;
a condensate water trough configured to collect condensate water formed in the process air circuit;
a component to be cleaned, the component being positioned within the process air circuit;
a rinse tank positioned above the component, the rinse tank includes an outlet opening and being adapted to store water;
a first lever arm rotatably fastened to the rinse tank, a second lever arm positioned outside of the rinse tank and coupled to the first lever arm, and a sealing head connected to the first lever arm and configured to close the outlet opening; and
an actuator configured to actuate the second lever arm to selectively open and close the outlet opening,
wherein the sealing head is configured to be opened to dispense the water from the fluid outlet opening of the rinse onto the component,
wherein the rinse tank is removable from the laundry appliance such that the first lever arm, the second lever arm, and the sealing head are removable with the rinse tank,
wherein the laundry appliance is configured to conduct the condensate water from the condensate water trough to the rinse tank, and
wherein the actuator is fastened on a receiving opening configured to guide the rinse tank.
