an air conveying device mounted adjacent to an exterior surface of the back side wall, the air conveying device having a first open end area communicated with a heating device and a second open end area communicated with a housing of a fan assembly and the air conveying device having a flow channel that is cross-sectionally closed such that the flow channel is self-contained;

a cover that covers the housing of the fan assembly and the flow channel, wherein the flow channel is disposed between the exterior surface of the back side wall and the cover; and

a sealing element disposed between the housing of the fan assembly and the cover.

2. The appliance as claimed in claim 1 , wherein the flow channel is formed by two parts with one of the parts being the back side wall that faces an exterior of the appliance and the other of the parts being an element having a U-shaped cross section and mounted on the back side wall.

3. The appliance as claimed in claim 1 , wherein the sealing element is mounted on one of a peripheral area of the housing and the cover.

4. The appliance as claimed in claim 1 , wherein the first open end area and the second open end area of the air conveying device are located opposite to each other and the flow channel is oriented essentially vertically.

5. An appliance for handling laundry items, in particular a clothes dryer, the appliance comprising:

means forming a laundry item handling area in which laundry items to be handled are received;

a housing in which the means forming a laundry handling area is located, the housing including a back side wall forming at least a portion of a back side of the appliance;

an air conveying device mounted adjacent the back side wall, the air conveying device having a first open end area communicated with a heating device and a second open end area communicated with a housing of a fan assembly and the air conveying device having a flow channel that is cross-sectionally closed such that the flow channel is self-contained;

a cover that covers the housing of the fan assembly and the flow channel; and

a sealing element disposed between the housing of the fan assembly and the cover,

wherein the sealing element is mounted on a peripheral area of the housing and facing the cover.

6. The appliance as claimed in claim 5 , wherein the sealing element completely surrounds a peripheral area of the housing.

7. An appliance for handling laundry items, in particular a clothes dryer, the appliance comprising:

means forming a laundry item handling area in which laundry items to be handled are received;

a housing in which the means forming a laundry handling area is located, the housing including a back side wall forming at least a portion of a back side of the appliance;

an air conveying device mounted adjacent the back side wall, the air conveying device having a first open end area communicated with a heating device and a second open end area communicated with a housing of a fan assembly and the air conveying device having a flow channel that is cross-sectionally closed such that the flow channel is self-contained;

a cover that covers the housing of the fan assembly and the flow channel; and

a sealing element disposed between the housing of the fan assembly and the cover,

wherein the sealing element is mounted on a peripheral area of the cover and facing the housing.

8. The appliance as claimed in claim 7 , wherein the sealing element completely surrounds a peripheral area of the cover.

9. An appliance for handling laundry items, in particular a clothes dryer, the appliance comprising:

means forming a laundry item handling area in which laundry items to be handled are received;

a housing in which the means forming a laundry handling area is located, the housing including a back side wall forming at least a portion of a back side of the appliance;

an air conveying device mounted adjacent the back side wall, the air conveying device having a first open end area communicated with a heating device and a second open end area communicated with a housing of a fan assembly and the air conveying device having a flow channel that is cross-sectionally closed such that the flow channel is self-contained;

a cover that covers the housing of the fan assembly and the flow channel;

a sealing element disposed between the housing of the fan assembly and the cover; and

a second sealing element disposed between the cover and the back side wall.

10. The appliance of claim 9 , wherein the second sealing element completely surrounds a peripheral area of the cover.

11. The appliance as claimed in claim 9 , wherein the second sealing element is mounted on the back side wall and facing the cover.

12. The appliance as claimed in claim 9 , wherein the sealing element is mounted on a peripheral area of the cover and facing the back side wall.

13. A clothes dryer for handling laundry items, the clothes dryer comprising:

a laundry item handling area in which laundry items to be handled are received;

a housing in which the laundry handling area is located, wherein the housing includes:

a heating device;

a housing of a fan assembly;
