As shown in Fig. 13, cal rod heat generator 37' is disposed or sandwiched between layers to improve the heat transfer between the heater and heating chamber 35'. First end 38' and second end 39' are in fluid communication with pump 31 and reservoir 9 to provide for a path of circulation of the fluid into and out of reservoir 9. »
- Heater 30 preferably has a heating chamber 35" and a printed resistive wire 34", which transfers the heat to the fluid that flows through heating chamber 35".
- First end 38" and second end 39" are in fluid communication with pump 31 and reservoir 9 to provide for a path of circulation of the fluid into and out of reservoir 9.
- the present invention provides a method of heating fluid in a foot spa through an in-line heater 30.
- Heater 30 transfers heat to the fluid when the fluid is outside of housing 5.
- Heater 30 also transfers heat to the fluid as it flows through the heater assembly.
- Heater 30 is not required to transfer heat through housing 5 and can provide for more efficient heating of the fluid at higher temperatures and rates without the risk of damaging housing 5. While the embodiments shown use in-line heater 30 in conjunction with heating wire 34, the present invention also contemplates the use of the heater assembly by itself.
- fluid deposited in the foot spa is optionally circulated by the fluid transport assembly in the housing.
- the pump preferably draws fluid deposited in the reservoir into the pump through an inlet and expels fluid into the reservoir via a "jetting" action through fluid jets (one shown in Fig. 1 , any number may be included).
- the fluid jets can have multiple outlets that may be selectively positioned in a vertical and/or axial orientation by the user and directed in a desired direction.
- the pump used by the foot spa may have any number or variety of pumps suitably sized and rated for application in the foot spa of the present invention.
- the reservoir is heated by a heater assembly and a heating wire.
- the heating wire is in thermal contact with the undersurface of the bottom wall, which allows heat transfer from the heating wire through the bottom wall of the housing to heat fluid in the reservoir.
- the heating wire is disposed in a serpentine-like shape, or other wave-like shape, along the undersurface of the bottom wall to increase the contact area and improve the heat transfer between the heating wire and the housing.
- the heating wire is preferably disposed between flanges formed along undersurface of the bottom wall. More preferably, heating wire is heat staked or otherwise adhered to undersurface of the bottom wall between flanges.
- the heating wire transfers energy or heat through the housing, which may limit the amount of energy or heat that can be transferred based upon the temperature tolerance of the housing. Therefore, an in-line heater assembly is preferably included to provide in-line heat or energy to the fluid as it is circulated or pumped into and out of reservoir.
- In-line heater assembly has a heating chamber integrally formed with an extrusion adjacent to, and preferably parallel with, the heating chamber.
- the extrusion has a heater disposed therein.
- the area of contact between heating chamber and extrusion is made of a material with high heat transfer properties to increase the efficiency of the heat transfer from the heater to the fluid flowing through heating chamber.
- the heating chamber and the extrusion are made from aluminum.
- the heater is a cal rod heater.
- the cal rod heater typically is able to provide about 300 watts of energy, as compared to the heating wire type heater that is limited to about 60 watts due to the lower temperature tolerance of the housing.
- foot spa 1 preferably can have an aeration system with a fluid circulation network having the pump discussed above, and one or more venturi mixers, all preferably retained substantially in the housing.
- foot spa 1 can have one or more air conduits 45 that are in fluid communication with a source of air 46 flow, such as an air pump.
- One or more air conduits 45 are connected to air exhausts 47, which are in fluid communication with reservoir 9.

- one button can be used to control on/off (i.e., activation/deactivation) of foot spa 1 and another button can be used to control the activation/deactivation of the fluid jets, heater, and/or aerating system.
- Roller actuator 50 may be operated to control the operation of the foot spa 1 among a number of operational modes. For example, a user may selectively rotate roller actuator 50 to cycle between (1 ) a fluid jet and heated mode, (2) a fluid jet and air bubble mode, and (3) a heated, fluid jet, and air bubble mode. It should be appreciated, however, that the particular functions invoked in each of the exemplary modes (1)-(3) may be varied in number and combination of features, including varying the number of modes.
- control switches 22 are covered by an at least partially elastic, pliable material that is preferably soft to the touch.
- the elastic cover preferably seals the mechanical and/or electrical components of control switches 22 from moisture and other environmental concerns such as dust and dirt. This aspect of the present invention is provided for prolonging the operational life and operation of foot spa 1.
- roller actuator 50 is covered in an soft elastic material, similar to that enveloping control switches 22.
- This aspect of the present invention also provides enhanced operational control of foot spa 1.
- the control switches 22 and roller actuator 50 may be manipulated (i.e., pushed and turned, respectively) by a user's foot. Accordingly, a user need not bend over to control the operational features of foot spa 1.
- all of the functions of foot spa 1 may be easily and conveniently accessed and controlled with a user's foot.
- remote control 48 such as that shown in Fig. 18.
- Remote control 48 has an internal power source (preferably batteries) and associated electronic circuitry for wirelessly transmitting a control signal to a receiver 49 located in or on-board foot spa 1.
- Remote control 48 enhances operation of foot spa 1 since the controls necessary to activate, control, and deactivate the various operational functions of the foot spa, are accessed and conveniently packaged in the remote control unit. Thus, one using foot spa 1 can control the various operations of the foot spa without impeding the relaxing context induced by operation of the foot spa.
- Wireless communication between remote control 48 and foot spa 1 may be accomplished using infrared, radio frequency (RF), sonic, or any other wireless communication format using any applicable protocol.
- Control panel 21 preferably has the controls for controlling the various features of foot spa 1 of the present invention.
- remote control 48 preferably has the controls for controlling the various features of foot spa 1 either directly or indirectly via the controls of control panel 21.
- function controls located on remote control 48, and thus controlling associated functions of foot spa 1 include, for example, an on/off control 52, vibration control 53, bubble control 54, fluid-jet control 55, and program control 56.
- on/off control 52 is sequentially depressed to activate/deactivate operation of foot spa 1.
- Vibration control 53 is sequentially depressed to activate/deactivate the vibratory mechanism of foot spa 1.
- Bubble control 54 is sequentially depressed to activate/deactivate the aerated bubbling function of foot spa 1.
- Fluid-jet control 55 is sequentially depressed to activate/deactivate the fluid "jetting" function of foot spa 1.
- program control 56 may be sequentially depressed in order to activate/deactivate an automated, programmed sequence of foot spa functions (e.g., vibration, bubble, and fluid-jet).
- the program may be predetermined (i.e., factory default) or selectively programmed by a user. In either event, the program may be associated with a time component that determines the length of time the program operates.
- remote control 48 may be adapted to reside in a remote control unit receptacle 50 disposed on or in foot spa 1.
- Remote control 48 can be selectively disassembled for facilitating access to, for example, batteries located therein and for replacement of the same.
- remote control 48 is assembled in a fluid tight fashion to make the remote control resistant to the penetration of fluid.
- remote control 48 preferably floats when disposed in fluid.
- Fig. 20 depicts foot bed inserts 57 that cooperate with foot spa 1 to provide a cushioned massage.
- Foot bed inserts 57 are preferably constructed of a rubberized material that is resistant to tearing and bacterial growth.
- foot bed inserts 57 can have holes that align with air outlet holes located in the bottom wall of the housing. In this manner, air expelled from the air outlet holes will not be blocked by foot bed inserts 57.
- cover 23 can have an array of massage fingers 58 as shown in Fig. 1.
- Massage fingers 58 may be used to massage the bottom and/or sides of the user's feet.
- a loofah 60 can be disposed on cover 23 over the array of massage fingers 58.
- Loofah 60 preferably has a sponge made of fibrous skeleton of the fruit of a loofah (i.e., gourd).
- loofah 60 is preferably made of an organic material, loofah 60 may be at least partially constructed of synthetic material.
- foot spa 1 can have an electrical cord 61 that is preferably stowed in an inner chamber of housing 5. That is, cord 61 may be retracted into housing 5 for storage in between uses of foot spa 1.
- Cord 61 is preferably wound around a reel (not shown) that is geared to manually operated reel 90 located on an exterior bottom surface of housing 5.
- a handle portion of reel 90 is foldable. In this manner, handle 92 may be folded flat during use and storage of foot spa 1 and unfolded for grasping when reeling cord 61 into housing 5.
- function controls discussed above are exemplary of the foot spa of the present invention and do not preclude the inclusion, exclusion, and combination of other foot spa function controls.
