Abstract

A domestic appliance for the care of items of washing includes a process air supply through which a stream of air is able to be directed through a drum for holding the items of washing, a mesh filter for separating the lint out of the air stream, a facility for removing lint from the mesh filter, the facility being embodied for removal of lint which is collected outside the process air supply on the mesh filter, and a rinsing device with which the lint is able to be rinsed out of the mesh filter with rinsing fluid. A method for removal of lint from a mesh filter of the domestic appliance also is provided.

Claims

1. A domestic appliance for care of items of washing, comprising:

a drum for accepting the items of washing;

a process air supply having walls defining a duct through which a stream of air is directed through the drum;

a mesh filter for separation of lint from the air stream, the mesh filter including;

a portion disposed between the walls of the duct of the process air supply and in the stream of air; and

a side edge disposed outside of the process air supply and outside the stream of air;

a scraper movable with respect to the mesh filter to remove the lint from the portion of the mesh filter and to collect the lint on a surface of the side edge of the mesh filter that is outside the process air supply and outside the stream of air; and

a rinsing device configured to direct rinsing fluid onto the collected lint on the surface of the side edge of the mesh filter to wet the collected lint to reduce an amount of space needed to store the collected lint and to remove the collected lint from the side edge of the mesh filter.

2. The domestic appliance of claim 1, wherein the rinsing fluid comprises a condensate in the domestic appliance during its operation.

3. The domestic appliance of claim 1, wherein the lint removed from the side edge of the mesh filter by the rinsing fluid can be directed into a floor pan of the domestic appliance.

4. The domestic appliance of claim 3, further comprising a collection vessel in a floor pan for the rinsing fluid laden with lint and for filtering the lint out of the rinsing fluid.

5. The domestic appliance of claim 4, wherein the collection vessel comprises an outlet through which the rinsing fluid from which the lint has been filtered out can be drained out of the collection vessel.

6. The domestic appliance of claim 5, wherein the rinsing fluid from which the lint has been filtered out is able to be drained out into the floor pan.

7. The domestic appliance of claim 4, wherein the collection vessel is removable from the floor pan.

8. The domestic appliance of claim 4, wherein the collection vessel comprises a filter device for filtering the lint out of the rinsing fluid, for allowing removal of the filtered lint from the collection vessel, and through which rinsing fluid can pass.

9. The domestic appliance of claim 1, wherein the domestic appliance comprises a condensing dryer.

10. A method for removing lint from a mesh filter in a process air supply of a domestic appliance for care of items of washing, the method comprising:

collecting the lint from an air stream in the process air supply using a portion of the mesh filter that is disposed between walls of a duct defining the process air stream, the portion between the walls of the duct being in the air stream;

moving, using a scraper, the lint that is collected on the portion of the mesh filter to a surface of a side edge of the mesh filter that is not between the walls of the duct and that is outside the process air supply and outside the stream of air such that the lint remains collected on the surface of the side edge of the mesh filter; and

removing the lint collected at the side edge of the mesh filter, which is not between the walls of the duct and is outside the process air supply and outside the stream of air, by directing a rinsing fluid to the side edge of the mesh filter and wetting the lint that is collected on the surface of the side edge with the rinsing fluid to reduce an amount of space needed to store the lint and rinsing the lint from the side edge of the mesh filter with the rinsing fluid to wash the lint from the side edge of the mesh filter.

11. The method of claim 10, further comprising directing the rinsing fluid laden with lint that has been rinsed from the side edge of the mesh filter into a floor pan.

12. The method of claim 11, further comprising filtering the lint from the rinsing fluid in a collection vessel in the floor pan.

13. The method of claim 12, further comprising draining the filtered rinsing fluid through an outlet in the collection vessel.

14. The method of claim 12, wherein the collection vessel comprises a removable filter through which the rinsing fluid can pass.
