DETAILED DESCRIPTION OF THE INVENTION

(6) Now referring to the drawings, a modular manicure station is shown and generally illustrated in the figures. As can be seen at FIGS. 1 and 2, a modular manicure station 10 generally includes a base or pedestal 12, positioned beneath and supporting an upper work surface 14. The base or pedestal 12 may be formed in any manner known in the art and has the primary purpose of supporting the work surface 14. The base or pedestal 12 may be positioned centrally beneath the work surface 14 or offset to one side as is depicted in the drawing figures.

(7) It should be appreciated that while a manicure workstation is described, the teachings herein can apply to any workstation wherein VOC and other toxic fumes are generated such as for example soldering workstations, chemical workstations. Accordingly, the term workstation is meant to encompass any type workstation and is not meant to be limited to manicure or salon type environments.

(8) The base 12 may work in conjunction with an end panel 16 such that the base 12 is at one end of the manicure station 10 while an additional support end panel 16, leg or legs is provided at the opposing end of the manicure station 10, thereby supporting the work surface 14 therebetween. A space 18 is provided beneath the work surface 14 to allow a person seated at the manicure station 10 to position their knees therebeneath such that their hands will rest comfortably on the upper surface of the work surface 14 for the manicure procedure. The base or pedestal 12 may include compartments 20, shelves or drawers therein to allow storage of the technician's belongings, tools and supplies as well as providing space to display manicure products and other salon products that may be offered for sale.

(9) In a preferred embodiment, the modular manicure station 10 is provided with an upper work surface 14 that is configured to create a high efficiency debris and odor removal system. As will be described in further detail below, the upper work surface 14 includes an integrated air cleaning system that operates on air flowing in a flow path having an inlet 24 within the upper work surface 14. More preferably, the upper work surface 14 has a slot inlet 24 that surrounds the periphery of the work area 26 along all of its sides. Alternately the upper work surface may have a grated inlet 25 that forms the entire work area. Beneath the inlet slot 24 or grate 25 may be provided a damper or baffle 27 to control and/or balance the airflow volume and velocity at the inlet.

(10) Turning now to FIG. 3, the slot inlet 24 is positioned above a plenum 30 contained within the upper work surface 14. The plenum 30 forms the space beneath the work area 26 to collect all of the air that flows downwardly and inwardly from the slot inlet 24 or grate inlet 25. The plenum 30 is in fluid communication with a manifold 32 such that the plenum 30 channels airflow into the manifold 32 that is shown running along one side of the manicure station 10. Alternately, the manifold 32 may be positioned centrally under the upper work surface 14, or along a left or right end of the work surface 14 and still fall within the scope of the intended disclosure. An air duct 34 having an inlet end 34a and a discharge end 34b is connected to the manifold 32 where the inlet end 34a is in fluid communication with the plenum 30 and manifold 32 and leads laterally from the plenum 30 to a fan 36 or other suitable collection, filtration of exhaust device outside the work area. Still more preferably, the collected air is discharged to an exterior of the work space within which the manicure station is contained to prevent any accumulation of VOC on the interior of the enclosed space.

(11) A particle collector bag or filter 23 may be positioned in the airflow path. The collector may be in the slot inlets 24 at the work area 26. Further the, particle collector 23a may be positioned at any location suitable and easily serviceable for cleaning and the like. Similarly, the bag or filter may include filtration media that is intended to serve as a means from scrubbing the various evaporated solvent fumes and other airborne VOC from the airflow prior to the discharge of the air to the exterior of the work space.

(12) The flow path, illustrated at FIG. 3, wherein the air is drawn inwardly through the slot inlets through the plenum, into the manifold and out the air duct is contoured with relative cross-sectional areas to establish, in use, relatively high air flow velocity through the duct to produce a high rate of debris removal from the work surface and to establish relatively low air flow velocity through the particle collector bag and filter bed to produce high removal rate of particles and odors in these elements.

(13) As depicted at FIG. 4, the manifold at the end opposite the air duct may be plugged using a plug 40 to prevent air leakage. Similarly, the manifold plug 40 may be removed to allow the connection to another workstation such that a plurality of such workstations can be connected together in series to a single airflow fan 36 source. Such fan 36 source is shown as being positioned either in fluid communication with said duct adjacent said discharge end or within said base of said workstation. The various components of the present air ventilation system fit into a space positioned outside the work area in a hidden manner such that the overall work station remains neat and uncluttered and the system is sufficiently powerful that fumes and nail dust created at the working area where the nail procedure is being carried out on the customer are effectively removed and yet the present ventilation system is located in an area outside the work space so that it is quiet and does not disturb the surrounding area.

(14) In one embodiment, as the manicure station 10 exhausts a volume of air, code requires that make-up air be provided to the space to maintain air pressure balance in the space. In this arrangement a return air duct 135 for makeup air is run concentric with the exhaust duct 34 in a manner that facilitates heat transfer from the conditioned room air to the incoming make up air. There can be seen a return manifold 133 adjacent the exhaust manifold 32 such that they share a common side. Preferably this side is configured and arranged to facilitate heat transfer via a heat transfer plate 136 that allows energy to be captured from the conditioned air being exhausted and transferred to the incoming makeup air. One skilled in the art can appreciated that this process may be a heating or cooling of the incoming make up air as the environmental conditions require. This allows the make-up air to be brought into temperature equilibrium using the energy from the exhaust air as they exchange heat through the common duct walls or heat exchange plate. Alternately the heat exchange bay be done using a remote heat exchange unit 135. The make-up air is then discharged into the space via a make-up air diffuser 124 positioned on the make-up air manifold 133.

(15) It can therefore be seen that the present invention provides a robust cleaning and ventilation system in a manicure table, employing table geometry to create high efficiency in debris and odor removal while providing a conditioned make-up air return that completes the full ventilation process. It can be further seen that the present invention provides a robust cleaning and ventilation system in a manicure table, employing table geometry to create high efficiency in debris and odor removal that includes a modular implementation such that the necessary equipment is not a single custom bespoke installation and can be used universally. For these reasons, the instant invention is believed to represent a significant advancement in the art, which has substantial commercial merit.

(16) While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
