2. Description of Related Art
Whirlpool bathtubs, spas, and hot tubs typically circulate water between a water intake and jets positioned beneath the water line of the whirlpool tub, spa or bath. Further, air is mixed with the water to increase the force on the body or skin of the user. Certain tub or spa designs have incorporated a unit to introduce a scent or aromatherapy into the bathing well when the air is mixed with the water before exiting the jets.

Various other designs for introducing aromatherapy in a tub or spa are known. In particular, U.S. Pat. Nos. 7,060,180; 6,723,233; and 6,405,387 to Barnes are generally directed to a jetted apparatus for tubs and spas. The apparatus comprises a structure for providing aromatherapy which may be combined with an ozone generator. The disclosed aromatherapy structure includes an enclosure in which an adapter is provided having a female threaded region extending into an interior of the enclosure and including a port adapted to receive a tube connecting the enclosure to an ozone generator. A cylindrical housing is open at both ends and has a male threaded region at one of its ends which is screwed into a female threaded region of an adapter. Ozone generated by the ozone generator flows through a disc shaped diffuser, which includes a porous material and serves to receive an aromatherapy compound or scented liquid in order to enrich ozone passing through the housing and the diffuser with an aromatherapy compound or scent vapor. Further, the enclosure includes a port which is connected with a tube to an air tube downstream of an air control valve to allow a fluid communication between the air tube and the enclosure.
U.S. Pat. No. 6,581,217 to Marcos is directed to a jetted bathtub in which a scent package is placed in a pipe section of the piping of the bathtub. As air flows through the pipe section, it passes through the scent package and picks up scent vapor from the scent package. Subsequently, the air scent mixture is blown out of an air outlet and directed to an area above the bathtub.
In one embodiment, an air control and aromatherapy module for a jetted tub is disclosed. The air control and aromatherapy module comprises an air control member having a body portion defining an intake opening, and a scent container defining a scent opening. The scent container is positioned adjacent to the air control member. The air control member defines a central passageway, and the scent opening of the scent container is in fluid communication with the central passageway. The air control and aromatherapy module may further comprise a housing having a body portion that at least partially encloses the air control member and the scent container with the housing further defining the central passageway. The scent container may comprise a body portion and an end portion defining a receiving space for an aromatherapy catalyst. The scent container may be positioned within the body portion of the air control member with the end portion of the scent container defining the scent opening. The air control member may further comprise a closed top positioned on an end of the body portion of the air control member.
Further, the body portion of the air control member may be cylindrical in shape having an inner threaded surface and an outer threaded surface, the body portion of the housing may be cylindrical in shape having an inner threaded surface, and the scent container may be cylindrical in shape having an outer threaded surface. The outer threaded surface of the scent container engages the inner threaded surface of the air control member, and the outer threaded surface of the air control member engages the inner threaded surface of the housing. The body portion of the housing may comprise an outer threaded portion with a housing nut engaged with the outer threaded portion of the housing. The housing may further comprise a flange extending from the body portion of the housing with the flange of the housing and the housing nut being configured to engage a tub deck.
In a further embodiment, an air control and aromatherapy module for a jetted tub comprising an air control member having a body portion defining an intake opening, a scent container defining a scent opening, and a housing having a body portion. The scent container is positioned within the body portion of the air control member. The air control member and the scent container are at least partially disposed within the body portion of the housing. The air control member and the housing define a central passageway and the scent opening of the scent container is in fluid communication with the central passageway.
In another embodiment, a method of providing aromatherapy to a jetted tub is disclosed. The method of providing aromatherapy to a jetted tub comprises the step of directing air through an intake opening of an air control member such that air enters the intake opening of the control member and passes through a scent container positioned within the air control member. The air control member and the scent container may be at least partially disposed within a housing. The method may further comprise the step of displacing the air control member relative to the housing to control a volume of the air directed through the intake opening of the air control member.

Although the air control member 30, the housing 50, scent container 65, and housing nut 85 are secured to each other using a corresponding thread engagement, the air control member 30, housing 50, scent container 65, and housing nut 85 may have any suitable fastening or securing arrangement. For example, the scent container 65 may have a friction fit engagement with the air control member 30. Moreover, although the scent container 65 is shown disposed with the air control member 30, the scent container 65 may be positioned differently relative to the air control member 30 such that the scent openings 74 are still in fluid communication with the central passageway 95 or air passing through the air control member 30. For example, the scent container 65 may be positioned on an end of the air control member 30 opposite the closed top 35.

During operation, the on/off control 106 selectively activates the whirlpool pump 108 to circulate water between the water inlet 104 and the jets 103 positioned within the bathing well 102 of the bathtub 100 via a common water line (not shown). The air control and aromatherapy module 25 is connected to the jets 103 via a common air line (not shown). The common air line may be secured to the housing 50 of the air control and aromatherapy module 25. The water line and the air line may be constructed from polyvinyl chloride (PVC), although other suitable materials for the lines may be used. Due to the water passing through the water lines, air is drawn within or directed to the intake opening 38 of the air control member 30 by venturi, principles through the air line and into the stream of water exiting the jets 103. In other words, a negative pressure is created by the water exiting the jets 103 to pull air through the intake opening 38 of the air control member 30, which passes through the central passageway 95, into the air line, and out the jets 103. The scent openings 74 of the scent container 65 are in fluid communication with the central passageway 95 such that the air entering the intake opening 38 passes through an aromatherapy catalyst in the scent container 65 and through the scent openings 74 for delivery to the jets 103. Accordingly, the air entering the intake opening 38 contacts the aromatherapy catalyst and carries the scent into the bathing well 102 when the air is mixed with the water in the jets 103. By selectively displacing the air control member 30 to change the amount that the intake opening 38 extends beyond the housing 50, as discussed above, the quantity of air passing through the intake opening 38 and through the scent container 65 and delivered to the jets 103 can be controlled as desired.
While certain embodiments of the air control and aromatherapy module were described in the foregoing detailed description, those skilled in the art may make modifications and alterations to these embodiments without departing from the scope and spirit of the invention. Accordingly, the foregoing description is intended to be illustrative rather than restrictive.
