Description
Background of the Invention
This invention relates to an apparatus for heating towelettes.
Moist, heated cloth towelettes are well-known, especially in Eastern cultures, for providing a refreshing way of cleaning up, such as after a meal, especially a meal with finger foods. Also, in this country, certain transportation services provide heated moist towelettes as a quick way to freshen up after a long journey.
While providing moist, heated towelettes (small towels) in commercial environments is well-known, the availability of such towelettes, which typically measure about 6 inches by 6 inches, for household applications appears to be non-existent.
Objects and Summary of the Invention
Accordingly, it is an object of the present invention to provide a heating device for warming towelettes.
It is another object of the invention to provide a towelette heating device suitable for use in the home.
It is yet another object of the invention to provide a towelette heating device for heating towelettes of cloth or other materials in a controlled fashion.
These and further objects of the invention will become more apparent upon consideration of the following commentary taken in conjunction with the appended drawings.
Briefly, a towelette heating device comprises:
(a) top, bottom and side walls forming a housing;
(b) a compartment within the housing and cover means on the top of the housing to permit access to the compartment, the cover being hingedly attached at one end to the housing;
(c) a heating element cooperatively retained within the compartment;
(d) heat-insulative means for supporting at least one towelette immediately above the heating element;
(e) means for substantially uniformly directing heat from the heating element onto the towelette, the means cooperatively retained in the compartment between the heating element and the support means; and
(f) circuit means adapted to supply power to the heating element and to be connected to a power source.
Thw towelette heating device of the invention controllably heats towelettes to a suitable temperature and is suitably employed in the home or office.

FIG. 2 is a rear elevational view of the towelette heating device of the invention; and
FIG. 3 is a cross-sectional view of the towelette heating device of the invention, taken along the line 3-3 of FIG. 1.
Detailed Description of the Preferred Embodiments
Referring now to the drawing wherein like numerals of reference designate like elements throughout, a towelette heating device of the invention is generally depicted at 10.
The towelette heating device comprises a housing 12 having a top 14, a bottom 16, front 18, rear 20 and sides 22, 24. The elements of the housing 12 define an interior compartment 26. The top 14 comprises cover means 28 to permit access to the compartment 26.
In particular, the interior compartment 26 is defined by inner walls 18', 20', 22', 24', partially in lower housing portion 12a and partially in upper housing portion 12b. The upper and lower housing portions are secured together by means such as bolts 13, blind threaded into housing 12.
The cover means 28, which is conveniently of a material that is at least partially transparent, such as a smoked plastic, is attached to the housing 12 by hinge means 30 (advantageously, there are two such hinge means 30), which permit the cover 28 to be rotated 90 degrees about the hinge means 30 to a free-standing upright position, as depicted in phantom in FIG. 3. Downwardly depending tab 32, in the center of the hinge means 30, prevents further backward movement of the cover 28 and helps support the cover in its upright position.
Access to lift the cover means 28 is provided by a depression 33, formed in the forward portion of the upper housing 12b. The cover 28 extends sufficiently beyond inner wall 18' to permit the fingers to securely lift the cover 28.
The cover 28 is provided with two downwardly depending sides 28a and 28b, which rest on indentations (not shown) provided in lower housing portion 12a. The cover 28 makes sufficient mating contact with the housing 12 to prevent excessive escape of heat.
Feet 34 (there are four such, one in each corner of bottom 16), comprise a non-marring material and provide support of the housing 12 on a surface (not shown).
A heating element 36 is supported within the compartment 26. The heating element preferably comprises a conventonal rubber heating pad, which comprises heater wires embedded in a silicone rubber matrix. Such a product is commercially available.
Support means 38, lying at least over the heating element 36, provides support for at least one towelette 40, which is to be heated or warmed in accordance with the teachings of this invention. Such towelettes are typically of terry cloth material and are 6 inches square (unfolded), although other absorbent materials and sizes may be employed. The support means 38 comprises a porous material that is a poor conductor of heat. A preferred example of such a heat-insulative material is a fiber glass mesh screen.
Heat directing means 42 substantially uniformly direct heat from the heating element 36 onto the towelettes 40. The heating directing means, which preferably comprises a metal plate, such as aluminum, is positioned in the compartment 26 between the heating element 36 and the support means 38. Thus, it will be appreciated that the support means 38 serves to prevent direct contact of the towelette 40 with the source of heat 42, and thereby reduce the possibility of over-heating of the towelette 40.
Power is supplied to the heating element 36 by means of AC power, provided through cord 44, which runs between wall plug 46 and the heating element 36. In particular, a switch means 48, conveniently a rocker switch, is used to turn the power on and off. The heating element 36 is preferably controlled by a thermostat 50, which prevents over-heating of the towelettes. Most preferably, a thermostat set to operate between about 110.degree. F. and 180.degree. F. is employed, specifically between about 140.degree. F. and 160.degree. F. A bracket 52 is used to hold AC cord 44 and to optionally permit retraction thereof into the casing 12 when not in use.
Operation of the device of the invention is as follows. The cover 28 is lifted up to its upright position. At least one towelette 40, moistened if desired, is placed in the compartment 26, on support means 38. The wall plug 46 is plugged into a suitable receptacle (if not already in place), and the switch means 48 is turned on. The cover 28, if not already lowered upon placement of the towelettes 40 into the compartment 26, is lowered.
After heating for a period of time (typically within minutes), the towelette 40 is removed from the device 10 and used for its intended purpose.
Thus, a towelette heating device for warming towelettes and the like has been disclosed. Many changes and modifications will readily occur to those of skill in the art, and all such changes and modifications will readily occur to those of skill in the art, and all such changes and modifications are intended to fall within the scope of the invention, as defined by the appended claims. Examples of such modifications include providing a timer to turn the device on and/or off at preselected times.
