Tumble dryer with a lint filter
View Patent ↗A tumble dryer is provided having a heat exchanger through which a process-air stream flows in a first direction and a first duct which is arranged in fluid communication with the heat exchanger through which a process-air stream flows in a second direction and in which a lint filter is disposed. A tray having its own lint filter is removably attached to the heat exchanger and arranged between the duct and the heat exchanger.
1. A tumble dryer, comprising:
a heat exchanger defining a passageway through which a process air stream can flow in a first direction;
a first duct in fluid communication with the heat exchanger and upstream of the heat exchanger and defining a passageway through which the process air can flow in a second direction;
a lint filter in the first duct and through which the process air stream passes in the first direction; and
a removable tray in fluid communication with both the heat exchanger and the first duct and disposed therebetween, the removable tray configured to divert the process air stream between the first direction and the second direction.
2. The tumble dryer according to claim 1 , wherein the tray includes a grating with which the tray is mounted on the heat exchanger.
3. The tumble dryer according to claim 1 wherein the tray includes a gripping surface.
4. The tumble dryer according to claim 1 wherein the tray is removable in a horizontal direction.
5. The tumble dryer according to claim 1 wherein the heat exchanger is configured for attachment with the tray.
6. The tumble dryer according to claim 5 , wherein the heat exchanger and the tray can be attached with a securing device with the securing device lying outside an area of the tray which influences the process-air stream.
7. The tumble dryer according to claim 1 wherein the tray is covered by a flap.
8. The tumble dryer of claim 7 , wherein the removable tray is removable through the flap.
9. The tumble dryer of claim 1 , wherein the tray is located at a lowest point in the process air stream from the first duct to the heat exchanger.
10. The tumble dryer of claim 1 , wherein the tray comprises:
a body section that diverts the process air stream flowing in the second direction from the first duct to the first direction and into the heat exchanger, and
a grating through which the process air stream flows in the first direction, the grating coupling the body section to the heat exchanger.
11. The laundry dryer of claim 10 , wherein the tray comprises:
a grip coupled to the body section on a side facing away from the grating.
12. The laundry dryer of claim 11 , wherein the tray comprises:
a seal between the grip and the body section.
13. A laundry dryer comprising:
a housing;
a drying space within in the housing;
a first duct that is in fluid communication with the drying space and through which a process air stream from the drying space flows in a vertically falling direction;
a lint filter arranged on the first duct and through which the process air stream flows in the vertically falling direction;
a heat exchanger arranged downstream of the first duct and through which the process air stream flows in a horizontal direction; and
a removable tray arranged between the first duct and the heat exchanger and in fluid communication with the first duct and the heat exchanger,
wherein the removable tray diverts the process air stream flowing in the vertically falling direction from the first duct to the horizontal direction and into the heat exchanger.
14. The laundry dryer of claim 13 , wherein the tray is located at a lowest point in the process air stream from the drying space to the heat exchanger.
15. The laundry dryer of claim 13 , wherein the tray includes a grating.
16. The laundry dryer of claim 15 , wherein the grating of the tray is coupled to the heat exchanger.
17. The laundry dryer of claim 13 , wherein the tray comprises:
a body section that diverts the process air stream flowing in the vertically falling direction from the first duct to the horizontal direction and into the heat exchanger, and
a grating through which the process air stream flows in the horizontal direction, the grating coupling the body section to the heat exchanger.
18. The laundry dryer of claim 17 , wherein the tray comprises:
a grip coupled to the body section on a side facing away from the grating.
19. The laundry dryer of claim 18 , wherein the tray comprises:
a seal between the grip and the body section.
20. The laundry dryer of claim 13 , wherein the removable tray is coupled removably to the heat exchanger such that the tray is removable from the heat exchanger in the horizontal direction.
21. The laundry dryer of claim 13 , comprising:
a securing device that secures the tray to the heat exchanger,
wherein the securing device is disposed outside of the process air stream.
22. The laundry dryer of claim 13 , wherein the housing comprises:
a flap through which the removable tray is removable from the housing.
23. The laundry dryer of claim 13 , wherein the housing comprises:
a flap through which the removable tray and the heat exchanger are removable from the housing.
