Abstract

For commercial and residential use, a wall-mounted enclosed towel warmer has a bottom-hinged tilt-out front cover which includes an integral top panel. In the tilted-out cover position an internal towel holder also tilts outward to provide convenient top access for loading or removal of a towel. When the cover is pushed closed, a latch retains it in the closed position where the exterior presents a smooth flat profile having only a shallow protrusion of a few inches from an unaltered wall surface, providing a high degree of user safety, especially regarding children. In this closed position, the towel becomes intimately sandwiched between several thin profile electric heating elements located on both sides of the towel holder and on inner surfaces of the enclosure, arranged to warm the towel uniformly to avoid hot and cold regions which tend to occur with conventional open type towel-warming devices. A front control panel provides touch pads and illuminated message displays. Automatic shutoff is provided in the event the warmed towel is not removed within a preset time, approximately 15 minutes, after which a new warming cycle could be initiated.

Claims

1. A towel warming device comprising:

a main body having a substantially rectangular back panel adapted to mount vertically against a wall, a pair of vertical side panels integral with said back panel, and a horizontal bottom panel;

a cover having a substantially rectangular main portion and an integral perpendicular flange portion, said cover being adapted to cooperate with said main body to form a substantially orthogonal enclosure when said cover is disposed in a closed position relative to said main body such that said main portion of said cover is disposed vertically in engagement with said side panels so as to form a front panel of said enclosure, and said flange portion is disposed horizontally so as to form a top panel of said enclosure;

a flat rectangular towel holder member disposed between said side panels and pivotedly attached thereto in a lower region thereof, on a horizontal pivot axis, such that when said cover is disposed in said closed position, said towel holder is caused to become constrained in a substantially vertical position disposed such that a towel may be contained within said enclosure, supported upon said towel holder;

hinge means, disposed along a horizontal hinging axis, hingedly attaching said cover at a lower edge thereof to said bottom panel of said main body, whereby said cover is provided with freedom to move rotationally from said closed position outward from said wall to a tilted open position constrained by stopping means to a predetermined angle less than 45 degrees from vertical, tilting of said pivotally attached towel holder being constrained to about half said predetermined angle, thereby providing access to a towel supported upon said towel holder; and

heating means adapted to warm a thusly supported towel.

2. The towel warming device as defined in claim 1 wherein said heating means comprises one or more flat substantially rectangular electrical heating elements each disposed against and affixed in one or more surfaces selected from the following surfaces of said towel warmer;

an inward-facing surface of said main body back panel, a first and second side surface of said towel holder member, an inward-facing surface of said vertical main portion of said cover, and a downwardfacing surface of said flange portion of said cover.

3. The towel warming device as defined in claim 2 wherein said heating element comprises a flat etched-foil type resistive metallic heating source encapsulated centrally between a pair of thermally conductive electrically insulating sheets.

4. The towel warming device as defined in claim 3 further comprising

a control panel located on an outside surface of said main portion of said cover;

a plurality of touch-sensitive keypads in a user-entry temperature-selecting group located on said control panel and adapted to enable a user to select a controlled towel temperature and to initiate energizing of said heating means upon entering such selection in said temperature-selecting user-entry sensor group;

thermostatic temperature control means, located within said enclosure, adapted to regulate average energy input applied to said heating means so as to temperature-limit said towel to a maximum temperature as selected by said temperature-selecting user-entry sensor group.

5. The towel warming device as defined in claim 4 further comprising:

a cover latch, mounted inside said enclosure in an upper region of said main body, adapted to latchedly engage said cover and to thus retain said cover in said closed position wherever said cover is manually moved into said closed position, said latch being further adapted to user-controllably disengaged said cover and allow said cover to move from said closed position to an open position such as to provide access to said towel holder for placing a towel thereupon.

a user-actuated opening sensor located on said control panel and operatively connected to said cover latch device, adapted to cause said latch device to unlatch said cover and thus allow said cover to move from said closed position to said open position in response to user actuation of said opening sensor.

6. The towel warming device as defined in claim 5 further comprising an illuminated temperature selection indicator located on said control panel and adapted to prompt a user to enter a temperature selection by way of said temperature selection sensor group whenever said cover is moved from said open position to said latched closed position in preparation for warming a towel place upon said towel holder.

7. The towel warming device as defined in claim 6 further comprising an illuminated warming indicator, located on said control panel and adapted to provide user indication of energizing of said heating means in response to entering said temperature selection by way of said temperature selecting sensor group.

8. The towel warming device as defined in claim 7 further comprising an illuminated ready indicator, located on said control panel and adapted to provide user indication of said towel being ready for use, having been warmed up to a selected temperature in accordance with said temperature selection.

9. The towel warming device as defined in claim 4 further comprising shutoff means adapted to automatically discontinue energizing of said heating means (a) whenever said cover is unlatched and opened for warm towel removal, and (b) whenever a predetermined heating time interval has elapsed without said cover having been unlatched and opened for warm towel removal.

10. The towel warming device as defined in claim 4 wherein said temperature selecting sensor group comprises three touch pads, designated "WARM", "MEDIUM" and "HOT", and said thermostatic temperature control means is adapted to temperature-limit said towel to a first, second and third maximum temperature respectively in response to temperature selection by way of actuation of one of said touch pads, said first, second and third maximum temperatures being designated as 110, 130 and 160 degrees Fahrenheit respectively.

11. The towel warming device as defined in claim 1 further comprising a latch adapted to retain said cover in said closed position, and to commandably release said cover so as to allow said cover to tilt outward to said open position.

12. The towel warming device as defined in claim 11 wherein said latch comprises a spring-loaded plunger adapted to engage a striker opening in said cover when said cover is moved to said closed position, so as to retain said cover in said closed position, and wherein said latch further comprises an electric solenoid adapted to retract said plunger when said solenoid is energized, in a manner to unlatch said cover and thus allow said cover to tilt outward to said open position.

13. The towel warming device as defined in claim 12 further comprising a control panel located on an outside surface of said main portion of said cover, said control panel comprising a opening touch pad adapted to cause said solenoid to be energized in response to finger pressure sensed by said touch pad, thus enabling unlatching of said cover from said closed position.
