The present invention relates to drying devices. More specifically, the present invention relates to self-contained, permanently-installed drying units that utilize a fan and a heater, are adapted to increase the efficiency of drying floors, and are segregated and/or separately controlled from the building's pre-existing HVAC system.
It often takes a substantial amount of time for sections of floor having a large surface area to dry after becoming wet, especially with sections of floor having a substantial amount of foot traffic. Fans or portable heaters can be temporarily set up to assist in drying the wet area of floor; however, they lack the ability to output enough heated air to substantially affect the rate at which the floor dries. To attempt to address these issues, the building's heat can be turned up and in some cases the rate of airflow of the building's HVAC system can be increased, but those attempted fixes affect the entire building or area of the building, which can make individuals in the building uncomfortable. Therefore, there is a need in the prior art for a self-contained air movement system that is segregated or separately controllable from the building's HVAC system and that comprises an outlet that is positionable adjacently to a floor surface when the system is installed within the building.
In view of the foregoing disadvantages inherent in the known types of air circulation or movement systems now present in the prior art, the present invention provides a segregated floor drying system that is separately controllable from the rest of the building's HVAC system, wherein the same can be utilized for providing convenience for the user when seeking to efficiently dry expanses of a wet floor without making the building or surrounding area of the building uncomfortable for occupants. The present system comprises an air duct having an inlet and an outlet, a fan, and a heater. The inlet is adapted to drawn air in either from the surrounding environment or is connectable to the building's existing air circulation ductwork. The present invention is adapted to serve as an air circulation and drying system that is separately controllable from a building's existing HVAC system. Furthermore, the outlet is designed so that it is positionable adjacently to a floor surface when the system is installed in a wall or to the exterior surface of a wall, thereby allowing the fan to blow air over the surface of the floor, increasing the efficiency with which the floor is dried. The present system further comprises a wireless transceiver for wirelessly controlling the functionality of the present system and various other activation mechanisms for separately controlling the fan and the heater without requiring direct user input.
Although the characteristic features of this invention will be particularly pointed out in the claims, the invention itself and manner in which it may be made and used may be better understood after a review of the following description, taken in connection with the accompanying drawings wherein like numeral annotations are provided throughout.
Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the drying system. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for drying wet floors utilizing a permanently-installed system that is installable into a building's existing duct work. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
The present invention is an air circulation and drying unit that is adapted to blow heated air across a floor and that is separately controllable from the building's pre-existing HVAC system. The present system can be installed such that it is completely segregated from the building's pre-existing HVAC system or it can be installed such that it draws air from the building's existing air circulation ductwork. In either case, the present system provides its own integrated heater and fan, thereby allowing the present floor drying system to be activated separately from the building's pre-existing HVAC system. This allows operators to increase the efficiency with which wet floors are dried by using heated air, without the need to increase the airflow rate and/or heat throughout the entire building.

The duct 11 is an elongated conduit having a continuous fluid passageway extending between an inlet 15 disposed at the upper end of the duct 11 and an outlet 12 disposed at the lower end of the duct 11. In an illustrative embodiment of the present invention, air is drawn in through the inlet 15 into the plenum housing 13 via a fan 16 disposed within the housing and then expelled by the fan 16 through the duct 11, out of the outlet 12. The plenum housing 13 further comprises a heater 18 disposed therein, which heats air as it is drawn into the plenum housing 13, prior to being expelled through the duct 11. In one embodiment of the present invention, the inlet 15 is positioned so that air is drawn into the present system from the surrounding environment, whereupon it is heated and then subsequently expelled. In another embodiment of the present invention, the building's existing air ductwork is connectable to the inlet 15 via any conventional means known in the prior art, allowing the present invention to draw air from the building's existing air circulation system.
The present invention further comprises a wireless transceiver 19 to which an electronic device, such as a cell phone, is connectable. The wireless transceiver 19 utilizes any wireless connection protocol known in the prior art, such as Bluetooth or WiFi. The wireless transceiver 19 allows users to control the present system without requiring direct, physical interaction with the system. The wireless transceiver 19 allows users to control a variety of functions associated with the operation of the system, such as, but not limited to, activating or deactivating the fan, activating or deactivating the heater, and setting the rate of rotation of the fan.
The present system is adapted to be modular and adaptable to a variety of different building configurations. The duct 11 is divided into a plurality of separable sections 20 secured together at the flanges 14 extending from the edges of the sections 20. The depicted embodiment of the present invention shows the duct 11 comprising two sections 20; however, any number of sections 20 can be secured together in order to alter the length of the duct 11 and allow the present invention to be customized for each particular building configuration.
The present invention further comprises one or more activation devices to provide additional functionality to the present system. The activation devices comprise any device, software, or hardware known in the prior art that is adapted to control the activation and deactivation of other devices, such as a heater or a fan, via the occurrence of a detectable variable. In an illustrative embodiment of the present invention, the activation devices comprise a motion sensor 17 disposed on the duct 11. In the depicted embodiment of the present invention, the motion sensor 17 is disposed adjacently to the outlet 12. The motion sensor 17 is in electrical communication with the heater 18, the fan 16, and other such components of the present system in order to control the activation and deactivation thereof. The motion sensor 17 is adapted to be programmable by a user. For example, the motion sensor 17 can be programmed to activate the heater 18 and the fan 16 when the motion sensor detects movement, i.e. foot traffic. Users can activate the motion sensor 17 on days having precipitation, thereby causing the system to automatically activate and initiate the drying of the floor any time foot traffic, which is likely bringing in water and making the floor slippery, is detected. This obviates the need for operators to manually activate and deactivate the system, thereby ensuring that the area of the floor towards which the present system is oriented remains dry at all times. In another illustrative embodiment of the present invention, the activation devices comprise a timer circuit.
The fan 16, heater 18, wireless transceiver 19, and other such components are in electrical communication with a power source (not shown). The power source comprises a rechargeable battery, an electrical cord connectable to a conventional wall electrical outlet, or any other such power source known in the prior art. The fan 16 comprises a centrifugal fan or any other such fan known in the prior art. The plenum housing 13 encloses all of the various components, segregating them from the surrounding environment and reducing the level of noise generated by the fan 16.
The present invention is alternatively mountable to either the interior surface of a wall or the exterior surface of a wall. When mounted to the interior surface of the wall, the present invention is substantially enclosed by the wall and hidden from view. When mounted to the exterior surface of a wall, the present invention is easier to access for repairs and modifications. An embodiment of the present invention further comprises a plurality of brackets 31 disposed along the front edge of the duct 11 for installing the present invention to the interior surface of a wall. Fasteners can be secured through the brackets 31 to mount the duct 11 to the interior surface of the wall. The brackets 31 are positioned along the front edge of the duct 11 so that the vent 12 is positioned such that extends through a complementary aperture in the wall and feeds into the room when the duct 11 is mounted to the interior surface of a wall.
An embodiment of the present invention further comprises a mounting plate 32 disposed on the rear surface of the plenum housing 13, which is adapted to engage with a receiving plate 34 that is attachable to the exterior surface of a wall by fasteners, adhesive, or any other means known in the prior art. In one embodiment of the present invention, the mounting plate 32 is removably attachable to the rear surface of the plenum housing by any means known in the prior art. In another embodiment of the present invention, the mounting plate 32 is integral to the plenum housing 13. The mounting plate 32 comprises a channel hook 33 extending therefrom and the receiving plate 34 comprises a receiver channel hook 35 extending therefrom. The channel hook 33 is adapted to removably engage with the receiver channel hook 35, suspending the duct 11 from the receiving plate 34 when the receiving plate 34 is mounted to a wall.
