Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a non-tumble clothes dryer.

2. Description of the Related Art

Conventionally, the process of doing laundry involves washing the laundry in a washing machine followed by drying the laundry in a tumble clothes dryer. However, some clothing items, such as those designated as delicates, are not made to withstand the tumbling that occurs in the clothes dryer, and some loads of laundry are relatively small, having only a few clothing items, to warrant drying the load in the clothes dryer. Rather than drying these clothing items in the tumble clothes dryer, they can be laid flat to air dry, such as on a drying rack, or dried in a non-tumble clothes dryer. Non-tumble clothes dryers dry the clothing items while they are stationary (i.e., laid flat or hung) rather than while tumbling.

Known household non-tumble clothes dryers are integrated with the tumble clothes dryer or configured to be a pedestal with its own cabinet that supports the tumble clothes dryer in an elevated position above the ground. The known pedestal non-tumble clothes dryer relies on the air supply and heating system of the tumble clothes dryer for operation. As a result, the pedestal non-tumble clothes dryer cannot be utilized as a stand-alone appliance separate from the tumble clothes dryer and cannot be moved to another location, such as above the tumble clothes dryer or above or below the washing machine. Additionally, the width of the pedestal non-tumble clothes dryer is limited to the width of the laundry appliance, but many clothing items are larger than this width when laid flat.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Referring now to the figures, FIGS. 1-9 illustrate a non-tumble dryer 10 according to one embodiment of the invention comprising a cabinet 12 and a drawer 14 slidably mounted to the cabinet 12 between a closed position, as shown in FIG. 1, and an opened position, as shown in FIG. 2. When the drawer 14 is in the opened position, a user can load fabric items, such as clothes, shoes, hats, linens, and the like, into the drawer 14 so that when the drawer 14 is moved to the closed position, the fabric items can be dried in the non-tumble dryer 10.

Referring now to FIG. 3, the drawer 14 comprises an open-top housing 20 formed by a bottom wall 22 and a peripheral wall having a pair of side walls 24 joined by a front wall 26 and a rear wall 28. The housing 20 forms an open-top drying chamber 30 having an inlet defined by a plurality of inlet apertures 32 formed in the bottom wall 22. As best viewed in FIG. 4, the inlet apertures 32 in the illustrated embodiment are generally circular and are arranged in a plurality of horizontal rows extending from near the front wall 26 to about midway between the front wall 26 and the rear wall 28. The inlet apertures 32, however, can have any suitable shape, size, and arrangement and can comprise a single aperture or a plurality of apertures that collectively have a desired cross-sectional area for airflow into the drying chamber 30. The drying chamber 30 has an outlet 34 defined by the open top of the housing 20. In the illustrated embodiment, the open top of the housing 20 is collectively formed by the upper edges of the peripheral wall 24, 26, 28. The drawer 14 further comprises a conventional slide 38 mounted on an exterior surface of each of the side walls 24 for slidably mounting the drawer 14 to the cabinet 12.

Referring back to FIG. 3, a drawer front 40 mounted to the front wall 26 of the housing 20 provides an aesthetic appearance to the drawer 14 and supports a control panel 42 for selecting a desired drying cycle and otherwise controlling the operation of the non-tumble dryer 10. The drawer front 40 includes a handle 46 formed below the control panel 42. The user can grasp the handle 46 when moving the drawer 14 between the closed and opened positions. The control panel 42 and the handle 44 shown in the figures are provided for exemplary purposed only; it is within the scope of the invention to utilize other types of control panels and handles and to locate the control panel and handle elsewhere on the non-tumble dryer 10.

The drawer 14 further comprises at least one drying rack 50 supported by horizontally aligned rack supports 52 mounted to or integrally formed with interior surfaces of the drawer housing side walls 24. The drying rack 50 comprises a frame 54 that surrounds a panel 56 upon which the clothing items can rest. The panel 56 is air-permeable so that air can flow from the inlet apertures 32 and through the panel 56 to the outlet 34 of the drying chamber 30. For example, the panel 56 can be made of a mesh material or can be a rigid framework that forms a plurality of holes. The frame 54 includes a pair of grips 58 that a user can grasp for mounting the drying rack 50 on the rack supports 52 or removing the drying rack 50 from the rack supports 52 and the drying chamber 30. The drawer 50 can comprise any desired number of the drying racks 50 and has a corresponding number of sets of rack supports 52. Optionally, the location of the rack supports 52 on the side walls 24 or the front and rear walls 26, 28 can be adjustable so as to adjust the vertical position of the drying rack 50 in the drying chamber 30. Alternatively, the drawer 14 can comprise several sets of the rack supports 52 fixed to the side walls 24 to provide several vertical positions for the drying rack 50.

The cabinet 12 comprises spaced top and bottom walls 60, 62 joined by a pair of spaced side walls 64 that are integrally formed with the top wall 60. The top, bottom, and side walls 60, 62, 64 are joined along their rear edges by a rear wall 66 to define an interior 68 of the cabinet 12 accessible through an opening 70 formed by the front edges of the top, bottom, and side walls 60, 62, 64. A track 72 is mounted to an interior surface of each of the side walls 64. The tracks 72 mate with the slides 38 on the drawer 14 in a conventional fashion to slidably mount the drawer 14 to the cabinet 12. The interior 68 of the cabinet 12 is sized to receive the drying chamber 30 when the drawer 14 is slid into the closed position through the opening 70. The cabinet 12 is structurally reinforced by a generally rectangular rear cabinet frame 74 near the rear wall 66 and a generally rectangular front cabinet frame 76 adjacent the opening 70. The cabinet walls 60, 62, 64, 66 and the rear and front cabinet frames 74, 76 are secured together with mechanical fasteners. However, it is to be understood that the cabinet walls 60, 62, 64, 66 and the rear and front cabinet frames 74, 76 can be secured together in any suitable manner and with any suitable joining processes. The cabinet 12 can be supported by a plurality of feet 78 mounted to the bottom of the cabinet 12.

With continued reference to FIG. 3, the cabinet bottom wall 62 supports a heating system 80 comprising a heating element 82 mounted to a heating element support panel 84 and positioned below a heat transfer plate 86. The heating element 82 can be any suitable source of heat, such as a gas or electric heating element, and is shown in the illustrated embodiment as a serpentine electric heating element that extends across substantially the entire surface area of the heating element support panel 84, which has a surface area slightly smaller than that of the cabinet bottom wall 62. The heat transfer plate 86, which is made of a heat conductive material and has a size comparable to that of the heating element support panel 84, is positioned above and in close proximity to the heating element 82 so that heat generated by the heating element 82 conducts through the heat transfer plate 86. The heating system 80 further comprises a pair of air guides 88 mounted to an upper surface of the heat transfer plate 86. Each of the air guides 88 has a relatively tall rear portion 90 mounted near a rear edge of the heat transfer plate 86 and an elongated front portion 92 extending diagonally forward and outward from the rear portion 90 before terminating near a side edge of the heat transfer plate 86. Thus, the air guides 88 form a generally V-shaped air duct or channel 94 that extends from the rear edge of the heat transfer plate 86 to about midway between the rear and front edges of the heat transfer plate 86, as best viewed in FIG. 5.

Referring again to FIG. 3, the cabinet 12 houses an air supply system 100 comprising a blower 102 disposed within a housing 104 defining an air inlet 106 and an air outlet 108 for the blower 102. The air inlet 106 extends across an upper portion of the housing 104 to expose a portion of the blower 102, and the air outlet 108 is a generally rectangular opening extending along a front portion of the housing 104. The blower 102 and the housing 104 are supported by a blower bracket 110 mounted to the rear cabinet frame 74 and to the heat transfer plate 86 such that the air outlet 108 is positioned between the rear portions 90 of the air guides 88, as best viewed in FIG. 5. The blower 102 is powered by a blower motor 112 mounted to the housing 104.

The heating element 82 of the heating system 80 and the blower motor 112 of the air supply system 100 are operatively coupled to a relay 122, which is operably coupled to a controller 120. The controller 120 in the illustrated embodiment is mounted to the rear wall 66 of the cabinet 12, and the relay 122 is supported by a relay bracket 124 mounted to the rear cabinet frame 74. The controller 120 is operably coupled to the control panel 42 and controls operation of the heating element 82 and the blower motor 112. The cabinet 12 further houses a power supply 126 for providing power from an external power source to the various components of the non-tumble dryer 10, such as the heating element 82, the blower motor 112, and the controller 120.

The cabinet 12 can be configured as a pedestal to support a laundry appliance 16 in an elevated position, as illustrated in FIG. 6. For example, the cabinet top wall 60 can include supports or brackets designed to mate with the bottom of the laundry appliance 16 and/or can form a recess sized to receive the bottom of the laundry appliance 16. According to the illustrated embodiment, the cabinet top wall 60 is configured to support the laundry appliance 16 in the elevated position as a result of being sized according to the laundry appliance 16. As shown in FIG. 6, the top wall 60 has a width W1 that is approximately equal to a width W2 of the laundry appliance 16 and a depth D1 that is about equal to or greater than a depth D2 of the laundry appliance 16. As a result of this geometry, the laundry appliance 16 can stably rest upon the non-tumble dryer 10. However, because the non-tumble dryer 10 is a stand-alone unit that does not rely upon the laundry appliance 16 for a source of air and/or heat, the non-tumble dryer 10 can be positioned in a location other than below the laundry appliance 16. For example, the non-tumble dryer 10 can be set upon the laundry appliance 16, positioned adjacent to the laundry appliance 16, located in another position relative to the laundry appliance 16, or used in any location without the laundry appliance 16.

An exemplary description of the assembly of the non-tumble dryer 10 follows. The following description is provided for illustrative purposes only and is not intended to limit the invention in any manner. The assembly process can proceed in any suitable chronology and is not limited to the sequence explained below.

To assemble the non-tumble dryer 10, the drawer 14 is assembled separately from the cabinet 12. The drawer 14 is assembled by mounting the front and rear walls 26, 28 to the bottom wall 22 and the side walls 24 to form the drawer housing 20. The drawer front 40 with the control panel 42 is mounted to the front wall 26 of the drawer housing 20, and the slides 38 are attached to the side walls 24. The rack supports 52 are mounted to the drawer housing 20 so that the drying rack 50 can be removably mounted in the drying chamber 30.

The cabinet 12 is assembled by mounting the tracks 72 to the cabinet side walls 64 and mounting the rear and front cabinet frames 74, 76 to the cabinet top wall 60 and side walls 64. The heating system 80 is mounted to the cabinet bottom wall 62, and the bottom wall 62 is attached to the assembly of the cabinet top and side walls 60, 64 and the rear and front cabinet frames 74, 76. The blower bracket 110 is coupled to the rear cabinet frame 74 and the heat transfer plate 86, and the blower housing 104 with the blower 102 and the blower motor 112 mounted thereto is connected to the blower bracket 110. The relay 122 and the relay bracket 124 are mounted to the rear cabinet frame 74, and the power supply 126 is positioned within the cabinet 12. The cabinet rear wall 66 with the controller 120 attached thereto is mounted to the rear end of the cabinet 12, and the feet 78 are mounted to the bottom of the cabinet 12.

After the drawer 14 and the cabinet 12 are individually assembled, the slides 38 on the drawer 14 are coupled with the tracks 72 on the cabinet 12 to slidably mount the drawer 14 to the cabinet 12.

An exemplary description of the operation of the non-tumble dryer 10 follows. The following description is provided for illustrative purposes only and is not intended to limit the invention in any manner. The operation process can proceed in any suitable chronology and is not limited to the sequence explained below.

To operate the non-tumble dryer 10, a user grasps the handle 44 on the drawer front 40 and slides the drawer 14 from the closed position of FIG. 1 to the opened position of FIG. 2. When the drawer 14 is in the opened position, the user can access the drying chamber 30 and can position items to be dried in the drying chamber 30, such as by setting the items on the drawer bottom wall 22 or on the one or more drying racks 50. If desired, the user can adjust the positions of the drying racks 50 relative to the bottom wall 22 and, when the drawer 14 contains more than one of the drying racks 50, relative to each other. After the items to be dried are positioned in the drying chamber 30, the user slides the drawer 14 into the cabinet 12 through the opening 70 to the closed position of FIG. 1. When the drawer 14 is in the closed position, the drying chamber 30 is fully received in the interior 68 of the cabinet 12, and the drawer front 40 closes the opening 70 and thereby the cabinet interior 68, as illustrated in FIG. 7. The user selects the desired drying cycle through the control panel 42, which communicates the selected drying cycle to the controller 120.

The controller 120 controls the operation of the heating element 82 and the blower motor 112 via the relay 122 to execute the selected drying cycle. As shown by solid line arrows in FIG. 7, when the blower motor 112 operates, the blower 102 rotates to draw air in though the air inlet 106 and exhaust air through the air outlet 108 into the air channel 94 formed by the air guides 88 on the heat transfer plate 86. The air flows forward through the air channel 94 and across the heat transfer plate 86, which conducts the heat from the heating element 82 to the air to heat the air, as indicated by dashed line arrows in FIG. 7. The heated air then turns upward and flows through the inlet apertures 32 in the drawer bottom wall 22 to enter the drying chamber 30. The heated air flows upward through the drying chamber 30 from the inlet apertures 32 to the outlet 34 and thereby dries the items to be dried in the drying chamber 30. If the drying rack 50 is in the drying chamber 30, the heated air flows through the drying rack 50 as it flows from the inlet apertures 32 to the outlet 34. After the air exits the drying chamber 30 through the outlet 34, the air is drawn rearward and into the blower 102 through the air inlet 106 to re-circulate the air in the manner just described. Thus, the non-tumble dryer 10 forms a closed air circulation path for drying the items held within the drying chamber 30.

When the selected drying cycle is complete, the user grasps the handle 44 on the drawer front 40 and slides the drawer 14 from the closed position of FIGS. 1 and 7 to the opened position of FIG. 2 to unload the items to be dried from the drawer 14. The user can leave the drying rack(s) 50 supported by the rack supports 52 when not in use, or the drying rack(s) 50 can be stored elsewhere. For example, the drying rack(s) 50 can be set on the bottom wall 22 of the drawer 14 or removed from the drawer 14 and placed in a separate location, such as between the conventional washing machine and dryer. Alternatively, the non-tumble dryer 10 can be adapted to store the drying rack(s) 50 in a recess or cavity, such as a cavity formed in the cabinet 12 above or below the drawer 14.

The non-tumble dryer 10 has been described above and shown in the figures as configured to function as a pedestal for the laundry appliance 16 and as having the width W1 about equal to the width W2 of the laundry appliance 16. However, it is within the scope of the invention for the non-tumble dryer 10 to function as a pedestal for more than one laundry appliance 16 or for the width W1 to be greater than the width W2. For example, the non-tumble dryer 10 can function as a pedestal for two of the laundry appliances 16 in a horizontal arrangement, as shown in FIGS. 8 and 9. In these examples, the width W1 is about equal to the sum of the widths W2 of the laundry appliances 16. In the example of FIG. 8, the drying rack 50 is sized to accommodate the width of the drawer 14, while the drying racks 50 in the example of FIG. 9 are sized similarly to the drying rack 50 shown in FIGS. 2 and 3 but are separated by a spacer 128. As stated previously, the non-tumble dryer 10 can be positioned above the laundry appliances 16 or in another suitable location.

FIGS. 10-17 illustrate a non-tumble dryer 150 according to another embodiment of the invention comprising a cabinet 152 and a drawer 154 slidably mounted to the cabinet 152 between a closed position, as shown in FIG. 10, and an opened position, as depicted in FIG. 12. When the drawer 154 is in the opened position, a user can load fabric items, such as clothes, shoes, hats, linens, and the like, onto the drawer 154 so that when the drawer 154 is moved to the closed position, the fabric items can be dried in the non-tumble dryer 150.

Referring now to FIG. 12, the drawer 154 comprises an upper drying rack 156 mounted to a lower drying rack 158, which is mounted to a drawer front 160. As shown in FIG. 13, each of the upper and lower drying racks 156 comprises a lower support 162 having a generally rectangular frame 164 that surrounds a plurality of interconnected ribs 166. The frame 164 is sized to receive an air-permeable panel 168, such as a mesh panel, and an upper support 170 comprising a frame 172 and plurality of horizontal ribs 174. Thus, the air-permeable panel 168 is sandwiched between the lower and upper supports 162, 170. The upper and lower drying racks 156, 158 are connected to one another at their rear ends by a pair of drying rack couplers 176. Each drying rack coupler 176 comprises a generally rectangular body 178 mounted to and extending upward from the lower drying rack 158, as best viewed in FIG. 14. The upper end of the body 178 is hingedly mounted to a bracket 180 mounted to the upper drying rack 156. The bracket 180 can pivot relative to the body 178 so that the upper drying rack 156 can pivot relative to the lower drying rack 158. The upper drying rack 156 is movable between a generally horizontal position shown in solid lines in FIG. 14 and a pivoted position shown in phantom in FIG. 14 so that the lower drying rack 158 can be accessed to position items to be dried on the lower drying rack 158. In FIG. 14, the air-permeable panel 168 of the upper drying rack 156 is not shown in phantom in the pivoted position for visible clarity of the figure. The drawer front 160 can include detents (not shown) on its rear side to support the upper drying rack 156 in the horizontal position. As in the previous embodiment, the drawer front 160 includes a handle 182 graspable by a user for moving the drawer 154 between the closed and opened positions. The drawer 154 further comprises a conventional slide 184 mounted to each side of the lower drying rack 158 for slidably mounting the drawer 154 to the cabinet 152.

Referring back to FIG. 12, the cabinet 152 comprises a top wall 190 integrally formed with depending left and right side walls 192, 193, and the rear edges of the top wall 190 and the side walls 192, 193 are joined by a rear wall 194, while the lower edges of the side walls 192, 193 and the rear wall 194 are joined by a bottom wall 196 substantially parallel with the top wall 190. Together, the cabinet walls 190, 192, 194, 196 define an interior 198 of the cabinet 152 accessible through an opening 200 formed by the front edges of the top, side, and bottom walls 190, 192, 193, 196.

The cabinet 152 further comprises a set of drying chamber walls comprising a drying chamber left side wall 202, a drying chamber right side wall 204, and a drying chamber rear wall 206. The drying chamber walls 202, 204, 206 extend vertically between the cabinet top and bottom walls 190, 196 such that air cannot pass above or below the drying chamber walls 202, 204, 206. Referring additionally to FIG. 15, the drying chamber left side wall 202 is parallel to and spaced from the cabinet left side wall 192 to form an inlet chamber 208 therebetween. The inlet chamber 208 is closed at the opening 200 by a control panel 210 mounted to the cabinet 12. Similarly, the drying chamber right side wall 204 is parallel to and spaced from the cabinet right side wall 193 to form an outlet chamber 212 therebetween. The drying chamber rear wall 206 is parallel to and spaced from the cabinet rear wall 194 to form a circulation duct 214 therebetween. The circulation duct 214 is closed at its left and right sides by the drying chamber left and right side walls 202, 204, respectively. Together, the drying chamber walls 202, 204, 206 and the cabinet top and bottom walls 190, 196 form a drying chamber 216 accessible through the opening 200.

Referring back to FIG. 12 and additionally to FIG. 16, an inlet to the drying chamber 216 is defined by a plurality of drying chamber inlet apertures 218 formed in a horizontal row near an upper end of the drying chamber left side wall 202. The drying chamber inlet apertures 218 fluidly couple the inlet chamber 208 with the drying chamber 216. Similarly, an outlet from the drying chamber 216 is defined by a plurality of drying chamber outlet apertures 220 formed in a horizontal row near a lower end of the drying chamber right side wall 204. The drying chamber outlet apertures 220 fluidly couple the drying chamber 218 with the outlet chamber 212. Furthermore, both the drying chamber left and right side walls 202, 204 have a plurality of apertures arranged in a vertical row near a rear end of the respective drying chamber side wall 202, 204 and function as an inlet and as an outlet for the circulation duct 214. The apertures in the drying chamber right side wall 204 function as circulation duct inlets 222 that fluidly couple the outlet chamber 212 with the circulation duct 214. Similarly, the apertures in the drying chamber left side wall 202 function as circulation duct outlets 224 that fluidly couple the circulation duct 214 with the inlet chamber 208.

A track 226 is mounted to an interior surface of each of the drying chamber side walls 202, 204. The tracks 226 mate with the slides 184 on the drawer 154 in a conventional fashion to slidably mount the drawer 154 to the cabinet 152. The drawer 154 slides into and out of the drying chamber 216 through the opening 200. The drying chamber 216 is sized to receive the upper and lower drying racks 156, 158 when the drawer 154 is slid into the closed position through the opening 200.

Referring to FIGS. 12 and 17, the cabinet 152 houses an air supply system 230 and a heating system 232 located in the inlet chamber 208 and operatively coupled to a controller (not shown). The air supply system 230 comprises a blower 234 disposed in a housing 236 defining an air inlet 238 and an air outlet 240 for the blower 234. The air inlet 238 extends across a lower portion of the housing 236 to expose a portion of the blower 234, and the air outlet 240 is a generally rectangular opening extending along a portion of the housing 236 that faces the drying chamber inlet apertures 218. The blower 234 is driven by a blower motor 242 mounted to the housing 236.

The heating system 232 comprises a heating element 250 that can be any suitable source of heat, such as a gas or electric heating element, and is shown in the illustrated embodiment as an electrical heating element supported by a conductive body 252. The conductive body 252 and the heating element 250 are disposed adjacent to the blower air outlet 240 and within an open face duct 254 having an opening 256 sized to receive the blower air outlet 240. The duct 254 is mounted to the drying chamber left side wall 202 such that the drying chamber left side wall 202 closes the open face of the duct 254. The duct 254 is sized to cover the drying chamber inlet apertures 218 so that air that flows from the blower air outlet 240 into the duct 254 is heated by the heating element 250 and leaves the duct 254 by flowing into the drying chamber 216 through the drying chamber inlet apertures 218.

Referring now to FIG. 18, the cabinet 152 is sized to overlie a pair of the laundry appliances 10 arranged in a horizontal side-by-side configuration. In the illustrated embodiment, the cabinet 152 has a width W3 substantially equal to a combined width W4 of the laundry appliances 16. As a result, the cabinet 152 completely overlies the pair of the laundry appliances 16 with the sides of the non-tumble dryer 150 and the laundry appliances 16 forming substantially continuous surfaces. The cabinet 152 can also be sized to partially overlie the laundry appliances 16 (i.e., the width W3 is less than the width W4) or to more than completely overlie the laundry appliances 16 (i.e., the width W3 is greater than the width W4). For example, the cabinet 152 can be sized to completely overlie only one of the laundry appliances 16. Furthermore, because the non-tumble dryer 150 is a stand-alone unit that does not rely upon the laundry appliances 16 for a source of air and/or heat, the non-tumble dryer 150 can be positioned in a location other than above the laundry appliances 16. For example, the non-tumble dryer 150 can function as a pedestal and support the laundry appliance(s) 16 in an elevated position. When the non-tumble dryer 150 is used as a pedestal, the cabinet top wall 190 is configured to support the laundry appliance(s) 150 in an elevated position as described above with respect to the non-tumble dryer 10. Further, the non-tumble dryer 150 can be positioned adjacent to the laundry appliance(s) 16, located in another position relative to the laundry appliance(s) 16, or used in any location without the laundry appliance(s) 16.

An exemplary description of the assembly of the non-tumble dryer 150 follows. The following description is provided for illustrative purposes only and is not intended to limit the invention in any manner. The assembly process can proceed in any suitable chronology and is not limited to the sequence explained below.

To assemble the non-tumble dryer 150, the drawer 154 is assembled separately from the cabinet 152. The drawer 154 is assembled by assembling the upper and lower drying racks 156,158 and coupling the upper and lower drying racks 156, 158 via the drying rack couplers 176. The lower drying rack 158 is mounted to the drawer front 160, and the slides 184 are attached to the sides of the lower drying rack 158.

The cabinet 152 is assembled by mounting the drying chamber walls 202, 204, 206 to the cabinet bottom wall 196. The air supply system 230, the heating system 232, and the duct 254 are mounted in the inlet chamber 208, and the tracks 226 are attached to the inside surfaces of the drying chamber side walls 202, 204. The cabinet top wall 190 and side walls 192, 193 are mounted to the cabinet bottom wall 196, and the rear wall 194 is coupled to the cabinet top, side, and bottom walls 190, 192, 193, 196. The control panel 210 is attached to the front of the cabinet 152 to close the inlet chamber 208.

After the drawer 154 and the cabinet 152 are individually assembled, the slides 184 on the drawer 154 are coupled with the tracks 226 on the cabinet 152 to slidably mount the drawer 154 to the cabinet 152.

An exemplary description of the operation of the non-tumble dryer 150 follows. The following description is provided for illustrative purposes only and is not intended to limit the invention in any manner. The operation process can proceed in any suitable chronology and is not limited to the sequence explained below.

To operate the non-tumble dryer 150, a user grasps the handle 182 on the drawer front 160 and slides the drawer 154 from the closed position of FIG. 10 to the opened position of FIG. 11. When the drawer 154 is in the opened position, the user can access the upper and lower drying racks 156, 158 to load items to be dried on the drawer 154. To access the lower drying rack 158, the user pivots the upper drying rack 156 upward to the position shown in phantom in FIG. 14. After the user places the items to be dried on the lower drying rack 158, the user pivots the upper drying rack 156 to the generally horizontal position so that the user can place items to be dried on the upper drying rack 156. After the items to be dried are positioned on the upper and lower drying racks 156, 158, the user slides the drawer 154 into the cabinet 152 through the opening 200 to the closed position of FIG. 12. When the drawer 154 is in the closed position, the drying chamber 216 fully receives the upper and lower drying racks 156, 158, with the upper drying rack 156 located vertically below the drying chamber inlet apertures 218 and the lower drying rack 158 located vertically above the drying chamber outlet apertures 220. Additionally, the drawer front 160 closes the opening 200 and thereby the drying chamber 216, as illustrated in FIG. 15. The user selects the desired drying cycle through the control panel 210, which communicates the selected drying cycle to the controller.

The controller controls the operation of the heating element 250 and the blower motor 242 to execute the selected drying cycle. As shown by arrows in FIGS. 15 and 17, when the blower motor 242 operates, the blower 234 rotates to draw air from the inlet chamber 208 though the blower air inlet 238 and exhaust air through the blower air outlet 240. The exhausted air flows into the duct 254 through the conductive body 252 whereby the heating element 250 heats the air. The duct 254 directs the heated air through the drying chamber inlet apertures 218 into the drying chamber 216. The heated air flows downward through the drying chamber 216 from the drying chamber inlet apertures 218 to the drying chamber outlet apertures 220 and thereby dries the items to be dried in the drying chamber 216. The heated air flows through the upper and lower drying racks 156, 158 as it flows from the drying chamber inlet apertures 218 to the drying chamber outlet apertures 220. The air exits the drying chamber outlet apertures 220 and enters the outlet chamber 212. Air from the outlet chamber 212 enters the circulation duct 214 through the circulation duct inlets 222 and flows through the circulation duct 214 before exiting into the inlet chamber 208 through the circulation duct outlets 224. After the air exits the circulation duct 214, the air is drawn into the blower 234 through the blower air inlet 238 to re-circulate the air in the manner just described. Thus, the non-tumble dryer 150 forms a closed air circulation path for drying the items held within the drying chamber 216.

When the selected drying cycle is complete, the user grasps the handle 182 on the drawer front 160 and slides the drawer 154 from the closed position of FIGS. 10 and 15 to the opened position of FIG. 11 to unload the items to be dried from the drawer 154.

The non-tumble dryer 150 has been described above and shown in the figures as comprising two of the drying racks, the upper drying rack 156 and the lower drying rack 158; however, it is within the scope of the invention for the non-tumble dryer 150 to comprise one of the drying racks or more than two of the drying racks. When the non-tumble dryer 150 comprises more than two of the drying racks, the drying racks positioned above a lowermost drying rack are preferably configured to move, such as by pivoting, so that the user can access the individual drying racks to place items to be dried on the drying racks. Moving the drying racks can also include completely removing the drying racks from the drawer 154. Further, the drawer 154 can comprise a support other than the illustrated drying rack for supporting the items to be dried.

Furthermore, the circulation duct 214 is shown as extending laterally behind the drawer 154, but it is within the scope of the invention for the circulation duct 214 to be located elsewhere in the non-tumble dryer 150. For example, the circulation duct 214 can extend above or below the drawer 154 or in front of the drawer 154.

The non-tumble dryers 10, 150 according to the invention can be modified while remaining within the scope of the invention. For example, the heating systems 80, 232 of the non-tumble dryers 10, 150 can be omitted such that the air supply systems 100, 230 blow non-heated air through the respective drying chambers 30, 216. When the heating system 80, 232 is included, the non-tumble dryers 10, 150 can comprise a temperature sensor to facilitate control of the heating element 82, 250 to control the temperature of the air in the drying chamber 30, 216. Additionally, each of the non-tumble dryers 10, 150 forms a closed air circulation path, but the non-tumble dryers 10, 150 can be modified so that the air that exits the drying chamber 30, 216 exits the cabinet 12, 152 rather than being re-circulated. It also follows that the cabinet 12, 152 can include a fresh air inlet so that the blower 102, 234 takes in fresh air rather than or in addition to re-circulated air. Furthermore, the blower 102, 234 can be configured to draw air through the air circulation paths in a reverse direction rather than the direction described above and shown in the figures by arrows. It is also within the scope of the invention for the drawers 14, 154 to be mounted to the cabinet 12, 152 for types of movement other than sliding movement. For example, the drawers 14, 154 can be pivotally mounted to the cabinet 12, 152. Additionally, the drawers 14, 154 can comprise other supports rather than the drying racks 50, 156, 158 to support items to be dried in the drawers 14, 154. For example, the drawers 14, 154 can comprise a rack specifically adapted to support shoes in a desired position for drying, such as an inclined position. Further, the non-tumble dryers 10, 150 can include an air distributor mechanism to provide jets of air against the rack and to equalize air flow distribution over the rack. An exemplary air distributor mechanism is disclosed in U.S. Pat. No. 6,860,032, which is incorporated herein by reference in its entirety.

The non-tumble dryers 10, 150 have been described as being stacked with the laundry appliance 16. Examples of the laundry appliance 16 include, but are not limited to, a washing machine, a dryer, a combination washing machine and dryer, or a non-aqueous non-aqueous washing apparatus. An exemplary non-aqueous washing apparatus is disclosed in U.S. Patent Application Publication No. 2005/0155393, which is incorporated herein by reference in its entirety. The non-tumble dryers 10, 150 can also be arranged relative to a module of a modular laundry system, such as disclosed in our Ser. No. 11/323,125, filed concurrently herewith, and titled “Modular Laundry System with Horizontal Modules,” our Ser. No. 11/322,715, filed concurrently herewith, and titled “Modular Laundry System with Horizontal Module Spanning Two Laundry Appliances,” our Ser.

No. 11/322,944, filed concurrently herewith, and titled “Sink Station with Cover,” which are incorporated herein by reference in their entirety.

The non-tumble dryers 10, 150 can also be used in conjunction with a work surface, examples of which are disclosed in the above-incorporated modular laundry system applications as well as in our Ser. No. 11/323,220, filed concurrently herewith, and titled “Modular Laundry System with Work Surface,” our Ser. No. 11/322,773, filed concurrently herewith, and titled “Modular Laundry System with Segmented Work Surface,” our Ser. No. 11/322,741, filed concurrently herewith, and titled “Modular Laundry System with Work Surface Having a Functional Insert,” our Ser. No. 11/322,740, filed concurrently herewith, and titled “Modular Laundry System with Work Surface Having a Functional Element,” and our Ser. No. 11/323,658, filed concurrently herewith, and titled “Modular Laundry System with Shelf Module,” which are incorporated herein by reference in their entirety.

The non-tumble dryers 10, 150 can optionally include a hanging element, such as the retractable hanging elements disclosed in the above-incorporated modular laundry system, laundry module, and work surfaces applications as well as in our Ser. No. 11/322,503, filed concurrently herewith, and titled “Retractable Hanging Element,” which is incorporated herein by reference in its entirety.

The non-tumble dryers 10, 150 according to the invention provide several advantages. The non-tumble dryers 10, 150 can optionally be utilized as a pedestal but can function independently of the laundry appliance(s) 16 and, therefore, be positioned in any desirable location relative to the laundry appliance(s) 16, such as on top of the laundry appliance(s) 16. Additionally, when the non-tumble dryer 10, 150 is utilized as a pedestal, the non-tumble dryer 10, 150 can execute a desired drying cycle while a conventional dryer supported by the non-tumble dryer 10, 150 executes a different drying cycle; the non-tumble dryers 10, 150 and the conventional dryer are not required to execute the same drying cycle when operated at the same time. The non-tumble dryer 10, 150 can be relatively wide so that clothing items that are relatively long, such as pants, can be completely laid flat on the drying rack 50, 156, 158 to dry.

While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation, and the scope of the appended claims should be construed as broadly as the prior art will permit.
