Abstract

Dryer appliances are provided herein including a cabinet having a lower panel and a drum rotatably mounted within the cabinet. The drum defines a chamber for receipt of articles for drying. A drawer is removably mounted to the cabinet and includes a front wall, a rear wall, and sidewalls extended between the front wall and the rear wall. The drawer forms a lint collection bin. A filter assembly is removably positionable within the lint collection bin. The filter assembly abuts the lower panel of the cabinet when the drawer is in a closed position.

First claim

What is claimed is:

1. A dryer appliance, comprising:
a cabinet comprising a lower panel;
a drawer removably mounted to the cabinet, the drawer comprising a front wall, a rear wall, and sidewalls extended between the front wall and the rear wall, the drawer forming a lint collection bin, the lower panel extending along a horizontal direction from the front wall to the rear wall of the drawer when in a closed position;
a filter assembly removably positionable within the lint collection bin, the filter assembly abutting the lower panel of the cabinet when the drawer is in the closed position, wherein the drawer comprises a track at which the filter assembly is removably positionable; and
a spring extending between the filter assembly and the drawer, wherein the spring is configured to force the filter assembly toward a flow of air entering the lint collection bin.

2. The dryer appliance of claim 1 , wherein the track extends at an angle between approximately 45 degrees and up to approximately 90 degrees.

3. The dryer appliance of claim 1 , wherein the track extends at an angle, wherein an upper portion of the filter assembly is more proximate to the front wall of the drawer than a lower portion of the filter assembly when positioned in the drawer.

4. The dryer appliance of claim 1 , wherein the track is positioned at one or more sidewalls of the drawer.

5. The dryer appliance of claim 1 , wherein the track is configured for the filter assembly comprising a vertical direction between approximately 12 inches and approximately 15 inches.

6. The dryer appliance of claim 1 , wherein the track is configured for the filter assembly comprising a lateral direction between approximately 19 inches and approximately 25 inches.

7. The dryer appliance of claim 1 , wherein the filter assembly is press fit or interference fit with the lower panel of the cabinet when in the drawer is in the closed position, wherein the track and the press fit or interference fit with the lower panel promote airflow through a filter of the filter assembly and mitigate flow around the filter.

8. The dryer appliance of claim 1 , wherein the spring extends from the rear wall of the drawer to the filter assembly.

9. The dryer appliance of claim 1 , wherein the spring extends from the front wall of the drawer to the filter assembly.

10. The dryer appliance of claim 1 , the cabinet comprising a rail extending along a horizontal direction, wherein the drawer is slidable along the rail, and wherein the filter assembly positioned at the lint collection bin formed at the drawer is slidable along the horizontal direction along which the rail extends.

11. A dryer appliance, comprising:
a cabinet comprising a rail extending along a horizontal direction and a lower panel;
a drawer slidable along the rail at the cabinet, the drawer comprising a front wall, a rear wall, and sidewalls extended between the front wall and the rear wall, the drawer forming a lint collection bin, the lower panel extending along a horizontal direction from the front wall to the rear wall of the drawer when in a closed position;
a filter assembly removably positionable within the lint collection bin, the filter assembly abutting the lower panel of the cabinet when the drawer is in the closed position;
a spring extending between the filter assembly and the drawer, wherein the spring is configured to force the filter assembly toward a flow of air entering the lint collection bin; and
a control panel mounted on the cabinet, the control panel in communication with a controller and a position sensor positioned at the rail, the position sensor in operative communication with the control panel to receive a signal from the position sensor indicative of whether the drawer is in an open position or the closed position.

12. The dryer appliance of claim 11 , the position sensor comprising a lock configured to secure the drawer to a bottom portion of the cabinet.

13. The dryer appliance of claim 11 , the drawer comprising a track at which the filter assembly is removably positionable.

14. The dryer appliance of claim 13 , wherein the track extends at an angle between approximately 45 degrees and up to approximately 90 degrees, and wherein an upper portion of the filter assembly is more proximate to the front wall of the drawer than a lower portion of the filter assembly when positioned in the drawer.

15. The dryer appliance of claim 14 , wherein the track is positioned at one or more sidewalls of the drawer.

16. The dryer appliance of claim 11 , wherein the rear wall forms a vent opening through which a flow of air exhausts from the lint collection bin.

17. The dryer appliance of claim 1 , wherein the rear wall forms a vent opening through which a flow of air exhausts from the lint collection bin.

18. The dryer appliance of claim 10 , comprising:
a control panel mounted on the cabinet, the control panel in communication with a controller and a position sensor positioned at the rail, the position sensor in operative communication with the control panel, the control panel configured to receive a signal from the position sensor indicative of whether the drawer is in an open position or the closed position.

19. The dryer appliance of claim 18 , the position sensor comprising a lock configured to secure the drawer to a bottom portion of the cabinet.
