AIR PURIFYING FLOOR DRYER

Abstract

The present invention provides a kit that may be added to existing floor dryers so that the dryers may purify the air it uses to dry floors while it dries the floors. The kit may be added to existing floor dryers or pre-installed on newly manufactured floor dryers. The kit includes an adapter that may be used to mount the kit to the intake of the dryer. It also includes an air filter that removes particulates from air drawn into the dryer. A UV light source is contained within the filter that also treats air drawn into the air dryer to kill microorganisms contained in the air before the air is blow out from the dryer to dry the floor.

DETAILED DESCRIPTION OF THE INVENTION

[0015] FIG. 4 provides an improvement to the whole room vertical floor dryer 40 illustrated in FIG. 3. More specifically, FIG. 4 illustrates the floor dryer 40 with an air purifying kit 55 installed thereto. The purifying kit 55, which is illustrated in exploded view in FIG. 5, generally includes each of an adapter 60 (see FIG. 5), filter 65, end cap 70, receptacle 75 provided on the end cap 70 (the end cap 70 and the receptacle 75 both at an upper portion 80 of the kit 55), and a UV light source 85 contained within the filter 65. The UV light source 85 is visible in each of FIGS. 4 and 5. The UV light 85 is visible in FIG. 4 because a section of the filter 65 has been removed for easier viewing.

[0016] The filter 65 provided in FIGS. 4 and 5 is preferably a HEPA filter that protrudes upwardly from the adapter 60 and thus the floor dryer 40. In some embodiments, the HEPA filter may be surrounded by a pre-filter (not illustrated). In operation, air that is drawn into the floor dryer 40 via the intake 45 first preferably passes through the filter 65 such that particulates are removed from the air.

[0017] Within the filter 65, the UV light source 85 may use known or foreseeable methods and systems to treat air that is drawn into the floor dryer 40 via the intake 45 and the filter 65 by illuminating the air with UV light. The UV light may kill microorganisms that are present in air that is drawn into the floor dryer 40.

[0018] When a cord such as cord 87 is plugged into a power source (not illustrated), power may be provided to the dryer 40 such that it can carry out its known and understood operation of drawing air through the intake 45 and expelling air through the blower (or in the case of FIGS. 1 and 2, through the intakes 5, 25 and from the blowers 10, 30, respectively). The end cap 70 may be located at the upper portion 80 of the filter 65, with the receptacle 75 located thereon. The receptacle 75 may include an electrical outlet (e.g., a three-pronged outlet) to which a cord, such as cord 90, may be coupled. When the cord 90 is plugged into a power source such as outlet 95 provided in the dryer 40, power may be provided to the UV light source 85 via the receptacle 75 such that it may provide power thereto. That way, the UV light may be illuminated within the filter 65 such that it can treat air that is drawn into the dryer 40 via the filter 65. In alternative embodiments, a single power source may be provided to operate the UV light and the dryer 40 (or dryer 1, 20) and its drying functions.

[0019] The adapter 60 is preferably attached to the floor dryer 40 at its intake 45. The adapter 60 may be mounted to the floor dryer 40, for example via screw holes 100 and screws 105 that are positioned to align with pre-existing holes (not illustrated in the dryer 40), though a number of ways are foreseeable. For example, it may be friction-fit to the intake 45. Alternatively, it may be snapped or otherwise releasably attached to the dryer 40. The adapter 60 may operate to attach the kit 55 to an existing floor dryer such as the dryer 40 with little effort or technical skill.

[0020] The adapter preferably includes a V-shaped support member 110 that extends upwardly from the adapter 60. The V-shaped member preferably includes an aperture 115 at an upper end 120 through which a fastener 125 may be received. The fastener 125 may also be received through an aperture 130 in the end cap 70 to secure the end cap 70 to the adapter 60. The filter 65 is preferably placed between the end cap 70 and the adapter 60. The filter 65 is further secured in place when the fastener 125 engages the end cap 70 to the adapter 60. Because the fastener 125 is easily disengageable to unsecure the adapter 60 and the end cap 70 from one another, it is easy for a user to replace the filter 65 at the end of its useful life. A user may do so by placing a new filter 65 between the adapter 60 and the end cap 70 before resecuring the adapter 60 and the end cap 70 to one another, thus securing the new filter 65 therebetween.

[0021] It should be noted that in alternative embodiments, the kit 55 may be provided as pre-installed on a dryer such as the dryer 1, 20, 40. It should also be noted that the kit 55 that is provided in FIG. 4 may be mountable to the floor dryer 20 the same way it can be mounted to the dryer 40, as described above. The kit 55 may also be attachable to the dryer 1 by installing it such that it covers the intake 5 that is horizontally-oriented rather than the vertically-oriented intakes 25, 45.

[0022] In operation, air drawn into the dryer 40 via the filter 65 first moves through the filter 65 such that particulates are substantially removed. Subsequently, the air passes by the UV light provided by the UV light source 85 contained within the filter 65 such that a substantial number of microorganisms within the air are killed. Air may then be expelled through the bottom of the dryer 40 via its blower (or in the embodiments of FIGS. 1 and 2, the blowers 10, 30 at the front of the dryers 1, 20, respectively). Similarly to a traditional air purifier, upwards of 99.97% of particles that are 0.3 microns or larger are captured by the HEPA filter. In addition, microorganisms may be killed by the UV light as they pass in close proximity to the light.

[0023] The above-described design allows existing floor dryers such as the dryers 1, 20, 40 to easily be converted to air sanitizers, purifiers, or disinfectors without having to purchase a dedicated machine. The kit 55 can be used with various models of dryers, including but not limited to, the dryers 1, 20, 40.

[0024] As is evident from the foregoing description, certain aspects of the present invention is not limited by the particular details of the examples illustrated herein, and it is therefore contemplated that other modifications, applications, variations, or equivalents thereof, will occur to those skilled in the art. Many such changes, modifications, variations and other uses and applications of the present constructions will, however, become apparent to those skilled in the art after considering the specification and the accompanying drawings. All such changes, modifications, variations and other uses in applications which do not depart from the spirit and scope of the present inventions are deemed to be covered by the inventions which are limited only by the claims which follow.
