The present subject matter relates generally to dryer appliances and circulation of air for drying in compartments apart from the dryer drum.
Conventional dryer appliances are generally provided with a single chamber for drying articles. That chamber is typically defined by a rotating drum. This arrangement works well for articles such as clothing, sheets, towels, and other linens, where the rotation of the drum generates turnover of the articles, iteratively exposing different portions of the articles to air circulating through the drum.
However, it is undesirable to dry certain articles within a rotating drum. For example, articles with hard or semi-hard surfaces, such as shoes or boots, generate significant noise if introduced into a conventional dryer appliance as the soles of the shoes strike the surface of the tub when they are tossed by the rotating drum. On some occasions, such hard-surfaced articles may even damage elements of the drying appliance.
Additionally, such conventional dryers may be inappropriate vessels for drying articles intended to maintain a particular shape, for example, due to the deformation of the articles from tumbling in the drum or from being crushed by other articles in a particular load. Hats and caps provide an example of such articles. Although this concern may be alleviated with the use of rigid frames that protect the shaped article from deformation, the frames themselves become problematic due to the hard surfaces, again generating undesirable noise and potentially damaging the dryer appliance.
Accordingly, a dryer appliance with a secondary drying chamber that remains stationary during a drying cycle is desirable.

Dryer appliance 10 includes a cabinet 12. Within cabinet 12 is a drum or container 14 (
Turning back to
The controller may be positioned in a variety of locations throughout dryer appliance 10. For example, the controller may be located at, adjacent to, or integral to cabinet control panel 58 in cabinet 12. In such an embodiment, input/output (“I/O”) signals may be routed between controller and various operational components of dryer appliance 10. As an example, the various operational components of dryer appliance 10 may be in communication with controller via one or more signal lines or shared communication buses.
Cabinet 12 may be divided into a lower portion 46 and an upper portion 47. Although lower portion 46 and upper portion 47 of cabinet 12 are depicted in the embodiments of
A first drawer 44 is removably mounted to cabinet 12 at lower portion 46 of cabinet 12. First drawer 44 is adjustable (e.g., slidable) between a closed position (
Referring to
A user of dryer appliance 10 may remove the filter assembly 100 from the first drawer 44 when the first drawer 44 is in the open position. With the filter assembly 100 removed from the first drawer 44, the user may clean or replace the filter assembly 100 and remove lint from within the first drawer 44. The user may adjust the first drawer 44 to return the filter assembly 100 to a suitable position for collecting lint during operation of dryer appliance 10. A poka-yoke arrangement between filter assembly 100 and first drawer 44 may assist with insuring that filter assembly 100 is properly or suitably positioned within first drawer 44 to capture lint during operation of dryer appliance 10.
Various embodiments of the filter assembly 100 include a filter element formed of any suitable filter material, including fiberglass, polyester, or cotton, or combinations thereof, suspended in a frame 106 (
Embodiments of the appliance 10 provided herein may allow for air filters generally used for residential or commercial heating, ventilation, or air conditioning (HVAC) systems to be used at the appliance 10. The drawer 44 may be sized to correspond to one or more standard air filter sizes for HVAC systems.
A second drawer 162 is also removably mounted to cabinet 12 at lower portion 46 of cabinet 12. In the embodiment of
Like, first drawer 44, second drawer 162 is adjustable (e.g., slidable) between a closed position (
A user of dryer appliance 10 may insert or remove item for drying, such as shoes, boots, hats, and the like, from the second drawer 162 when the second drawer 162 is in the open position. Second drawer 162 may be entirely empty in certain embodiments. In other embodiments, shelves, hooks, posts, and/or other such elements may be present to accommodate placement and spacing of the articles for drying.
As previously explained, drum 14 is rotatably mounted within upper portion 47 of cabinet 12. A rear wall of drum 14 may be rotatably supported within cabinet 12 by a suitable fixed bearing. A drum motor (not pictured) rotates the drum 14 about a horizontal axis. For example, the drum motor may be coupled to drum 14 via a pulley and belt system or the drum motor may be directly coupled to drum 14 and directly drive drum 14. Drum 14 further includes a drum air inlet 154 and a drum air outlet 156. Drum air inlet 154 is in fluid communication with air intake opening 150 and is attached to an end of first air duct 160.
Drum 14 is configured to receive heated air that has been heated by a heater assembly 164, e.g., in order to dry damp articles disposed within chamber 16 of drum 14. During operation of dryer appliance 10, drum 14 rotates and first fan 168 circulates air through first air duct 160 and chamber 16 of drum 14. In particular, ambient air enters or passes by heater assembly 164 in a conventional manner due to first fan 168 urging such ambient air into or by heater assembly 164. Ambient air is heated by heater assembly 164 and continues as heated air through first air duct 160. First fan 168 then circulates such heated air through drum air inlet 154 and into drum 14. The heated air passed through drum 14 and exits through drum air outlet 156.
Drum air outlet 156 is attached to an upstream end of a second air duct 166. Second air duct 166 is a duct in the preferred embodiment, but one of ordinary skill in the art will recognize that second air duct 166 could, in alternative embodiments, take the form of one or more of a tube, pipe, conduit, or any other known manner for guiding air from one point to another.
First drawer 44 is situated directly below a downstream end of second air duct 166. In the embodiments of
First drawer 44 further includes a first drawer air outlet 158 on rear wall 244 of drawer 44. As previously explained, first drawer 44 further includes filter assembly 100. Filter assembly 100 is situated upstream of first drawer air outlet 158. After heated air that has passed through drum 14 is introduced to first drawer 44, it travels toward first drawer air outlet 158 and through filter assembly 100, which traps lint and removes lint particles from the lint and moisture laden air. The lint may generally be captured at an upstream side of the filter assembly 100.
As a result of the reduction in air pressure resulting of passage of air from air intake opening 150 to first drawer air outlet 158, and through filter assembly 100 in particular, dryer appliance 10 may further include a second fan 170 in the lower portion 46 of cabinet 12, as shown in the embodiment of
Although the present disclosure is described in the context of the physical arrangement of the embodiment of
Referring now to the top view shown in
After travelling through second drawer 162, air may exit dryer appliance 10 through air exhaust opening 152 (i.e., second drawer 162 is in fluid communication with air exhaust opening 152. Air exhaust opening 152 may be situated on surface 151 of cabinet 12. As shown in the embodiments of
Air exhaust opening 152 may also be offset from first drawer air outlet 158 in one or more of the lateral and vertical directions. This placement may vary depending upon the physical relationship between first drawer 44 and second drawer 162 (e.g., side-by-side or vertically stacked). Offsetting air exhaust opening 152 from first drawer air outlet 158 discourage air passing out of first drawer 44 from exiting through air exhaust opening 152 without first circulating through second drawer 162. The arrangement further generates air turbulence, which aids in circulating air through second drawer 162 and drying the articles therein.
